That's awesome. Thank you everyone for the info and the testing. I will perform this mod once I get my resistors from digikey and my switchbacks next week. This is way cleaner than the those damn load resistor in the trunk and hood.

You guys are AMAZING!!!! I have wanted LED's in the front and back so bad but there was no way I was going to do a rig job and use load resistors that get hot as shit. Finally the right way to do it, and its easier than doing load resistors!! sweeet!

Mafyoso,
What would be the best LED's to get? What LED's are you running in the rear and where did you get them? Thw switchbacks looks nice but I think I just want a standard amber LED in the front. Looking for recommendations because I want to purchase today asap.

Thanks,
James

Hey James here is what I'm running in the Rear:
http://cgi.ebay.com/ebaymotors/ws/eB...#ht_4337wt_848

These are the switchbacks I'm running in the Front:
http://cgi.ebay.com/ebaymotors/ws/eB...ht_1895wt_1165

I Got them from eBay because 1. They were Cheaper and 2. The Ebay Stores were from USA. I was in a hurry to get them quick so I ordered Friday and received everything on a Monday/Tuesday. I needed the Rear ones ASAP since the tails I ordered had the OEM Rear Turns which were halogen white, I didn't want to get a ticket. In the state of Florida they need to either be red or amber colored in the rear of your car. I was really surprised with the shipping from eBay especially the switchbacks which got here pretty quick from Cali and my rears which were in GA got here a day later. IDK how that happened since i am a state away from GA... The switchbacks are nice, I like the fact that they match my 8000k HID Low/High Beams at the same time match my front Side marker and Turning Signal on my Mirrors when I am turning. The rears are Red LEDs which I love. I was thinking about going Amber with them as well but the Red matches my brake lights and rear side markers well. I like them a lot but think the switch backs could be a little brighter. Maybe next set ill try some form V-LEDs.com to see if they are a little brighter. I tried to match the specs from V-LEDs to the ones on eBay as much as possible and those are the links I came up with. All in ALL the LEDs look 1000x better than the Halogen bulbs.

^^^ Alright thanks for the info. I decided to just get standard amber for the front since im not changing any other bulbs. Only headlight mod I have is ZKW clear lenses with OEM bulbs. After some searching it looks like these are what im going to get:

Front:

Yeah Please do Post Pics and Video, I'm interested in those Rears you purchased with 54 Lights, Mines have 48. I may go that route if they look brighter.

Alright I will definately take pics and HD vids when I get them in. I just ordered them today from Vleds and im trying to track down some resistors locally otherwise I will order those online too. My buddy said he found a .05 ohm high wattage resistor. I wonder if that would work...any ideas?

Should work cause two .12ohm resistors make .06 from what I understood from earlier post. So Yeah 2 x .12 should = 1 x .06 and 1 x .05 should work fine.

I do like those switchbacks. Does v-led make a comparable switchback light. Would rather order all at one place.

And what will resistors do to factory lights if soldered before getting lights or if in a pinch had to resort back to oem.

VLEds Does sell Switchbacks here are a few links to one of them

You need 1157 bulbs. Im not sure what would happen if you have the resistors installed without LED Lights. My Guess would have to be that the Halogen bulbs wouldn't be bright at all since the resistors aren't generating enough power for them. But im not sure about that.

The resistors have no influence on the lights themselves or their output. You can reinstall your halogens no problem there will be no difference except when you have a bulb out its not going to tell you by hyper flashing.

FYI resistors don't generate power they actually do the opposite they resist The resistor is only used to define the current "sense" point and relay this message to the micro controller which will decided to hyper flash or not. By lowering the sense point you are essentially telling the micro controller that the lower current draws from the LEDs are acceptable and hyper flashing is not necessary. Halogen bulbs are going to be way above the current sense point which just means they will never be able to activate hyper flashing.

Just to give you guys a heads up my local Fry's Electronics (Chicago area) stock .12ohm resistors. I know its just as easy to order from online, but if its something you want right away it is possible to find them locally. Radio Shack does not carry these, but I will be stopping by Fry's today or tomorrow to pick a couple up. My LED's are also in town and should arrive today or tomorrow via USPS. I am doing front and rear LED's on a 08 Type S. I purchased V-LED's 54 SMT's so I will for sure post pics and vids when im done.

Need some input its not working perfectly for me. Im using vleds front and rear LED's so I assumed I needed to use either two .12's in parallel or one .06. My local Fry's had the .12's so I used those and soldered them in parallell. I put everything back together and only the front LED's work. They flash at normal rate and neither of the rear turns work at all. However if I put the standard bulb back in it works just fine. Here are pictures I took can someone please help me out here. I also took a picture of the resistors I bought from Fry's so you can tell me if these are the correct ones.

Any help is greatly appreciated.

Thanks,
James

humm Well first can you confirm the LEDs are functional? Hook them up to a known working 12v source? Wouldn't surprise me to hear they were DOA.

After that I would first try one .12 in the flasher and see if that works for you. Can you post the specs on the VLEDS? Looking for power draw watts or mAh.

I have a feeling this is LED related though.

The two rear red LED's work just fine I tried them prior to messing with the turn signal relay. Also, I just noticed that even though the front LED's flash correctly they do not go on when I put the parking lights on. Yeah this is odd that the standard bulb works, but the LED doesn't. You would think since the circuit out back at the bulb holder is getting 12v it should light up.
So after all this I re-examined my resistor install and it's perfect as far as I can tell. I then removed one of the resistors and that didn't make a difference. So as it stands the rear turn signals only work with a standard halogen bulb, the front LED's work and flash correctly, but will not go on with parking lights.
As for the specs on my LED's see one of my posts above I put a link in for the exact ones I ordered.
I'm at work now so can't mess with it anymore, but I'm definitely looking for some ideas.

Thanks,
James

Humm the only think I can think of is check your fuses. If you put all your halogens back with the modified relay everything works fine?

Can't be the fuses if all the lights technically work. What I'm first going to do is put the original shunt resistor back in and see if all the LED's function. Obviously they should hyper flash but I would like to atleast know they work correctly otherwise both front and back.

Well I messed with it a little more tonight and no luck. Ahh well not a big deal I'm not going to mess with it anymore because the last thing I wanna do is screw up my electrical system.

So I'm just going to sell my new Vleds that I received the other day. I have front amber 54 smt's and rear red 54 smt's. They looked amazing when I tested them out. I paid $65 shipped and will let them go for $50 shipped. I will even throw in a couple .12 ohm resistors. Email me at [email protected] or call/text at 847-769-7307 if interested. I accept paypal (same as my email above). I ship same day I receive payment.

Thanks,
James

did you test it with the original shunt resistor back in and for the rears, have you tried flipping it around? it wont work if you dont have the polarity correct.

Well what did you try ? If you have halogen bulbs in the rear does everything work normally with the 2 x .12 ohm resistors? Did you go back to the shunt and get hyper flashing with the LEDs? I'm sorry I dont have LEDs in my brake lights but we have one confirmed user here and it sounds like it has to do with the LEDs or their connection to the socket. Not to mention the turn signal circuit is tied together Left to Right not front to back which.

Resistors are non polar orientation makes no difference.

Well right now it's back to 100% stock. Standard bulbs and normal shunt resistor. When I noticed interior lights randomly flickering I got nervous and said I'm done screwing with it. It also seemed that the front turn signal connectors got extremely hot. The good thing is nothing appears to be messed up everything works perfectly back to normal. I still want LED's but now I'm kind of worried about messing with that stuff after seeing center instrument lights flickering with my turn signals.
I did not try rotating the LED's 180 degrees I didn't think polarity of those mattered.

humm it sounds like you have a short or bridged a connection somewhere if your getting interference between your turn signals and running lights. Did you ever take a picture of the back of the turn signal relay after you soldered it? There is really no plausible reason swapping the resistors could directly cause any of those problems unless something was bridged or connected wrong on the relay circuit board. I wouldn't give up so easily there has to be an explanation to your symptoms.

PS your right about the resistors they are non polar

As for the polarity I was speaking of the actual LED's. I think someone above mentioned maybe the rear turn signal LED's need to be put in a certain way. I didnt think thats the case but I should have tried turning them around just for grins.

I also was thinking, could have I bought the wrong front LED's? Since they did not turn on as normal parking lights maybe they were not the right bulbs and the reason there were some issues? The ones I bought say 1157.

As for the circuit board as far as I could see my solder job was flawless. I ensured no solder got onto any other part of the board. To me it looked perfectly fine and my solder job literally looked identical to the original solder job from the factory on the shunt resistor.

Roger555 & Mafyoso:

Thank you my Acurazine brethren. Solder the two 12ohm resistor on to the turn signal relay per your pix and it fixed the hyper flashing. Next up is to get the headlight mods and install the switchbacks.

This is an awesome forum. If you guys get a chance, check out the update on the mods to my TL:

Ok this is really weird. So now I'm messing with the rear LED's and it turns out they only work when installed a certain way so I guess the LED bulbs polarity needs to be right. What's also weird is that now I get no hyper flash with rear LED's installed and the resistor is 100% stock with the shunt resistor. Wtf.

I want to double check, exactly what rear And front LED's should have I bought for my 08 TL? The original rear bulb says 7440 I think it was and I know the front is a two filament bulb or parking light and turn.

Thanks,
James

When you tested this did you have the halogens in the front still? That is weird that they would flash normal because I'm pretty sure the front & rear halogens both draw 21W. The LEDs you bought must draw enough current to keep its above the hyperflash sense point with the stock resistor. Does the circuit hyperflash if the try the signal without anything in the rear?

Dammit I really wish I would have known about this earlier this year when I used resistors for my rear LEDs. This is so much cleaner than having to mount the resistors and tap wires, etc.

I want to double check, exactly what rear And front LED's should have I bought for my 08 TL? The original rear bulb says 7440 I think it was and I know the front is a two filament bulb or parking light and turn.

Thanks,
James
Damn ur setup is going crazy... The rear LEDs should be Single filament for turning signals only and the fronts LEDs are Double filament for the Parking lights and Turning signal. When i put in my rear LEDs with Halogen fronts they hyper-flashed right away with the turning signal but flashed normal with the Hazards lights. Im guessing thats normal? Check to see if ur using ur hazards or turning signal check u test them out again. GL

Yeah I dont know whatsup. I ended up messing with them again last night and tried all sorts of configurations. I put in just the rear LED's and as weird as it may sound there was no hyperflashing and that was with regular bulbs in front and shunt resistor. So I get home and re-install the front LED's however this time they turn on as they should with parking lights. After that though the turn signals didnt work at all. So I once again tried the resistors and thats where stuff got goofy again. Some interior lights started flickering when I put the turn signals on and sometimes they didnt even work at all. Im done screwing with it because the last thing I want to do is mess up my electrical system. Im going to see if I can just return the LED's unless someone here wants them.
I dont see why it would be different but who knows maybe since I have a real late built 08 there is some change we dont know about. All normal bulbs are back in and the turn signal relay was put back to stock and its working perfectly.

Thanks for all the help anyway guys im glad its working for most of you.

Will this same principle apply to the 4G TL? Please advise.

I Think the Same principle will apply Ive heard some honda Freaks do this for there hyperflashing issue. Try it and see if it works. Its a simple mod and I dont think it will hurt anything since ur lowing the resistance of the relay

I will take a look at the relay and keep you guys posted. I hope it is not like the '08 TL where it was a PITA to take out.

Ordered 10 resistors in from Digikey so hopefully I'll get this done this weekend if I get done installing the new garage flooring (G-Floor Parking Pad). This will allow me to take out my load resistors that I installed above the tail lights.

If anyone else in KC is wanting to do this mod, I have extra resistors!

as usual my car likes to make things difficult. i'm stuck on step one ;removing the relay. do you pinch the silver thing and pull or just pull? because i've tried both and it's not budging at all. even tried using vice grips and ended up cracking the silver casing. i hate my car
