LED blinkers

ok, ive talked about these before, but BEBBER came and saved the day by estimating the correct setup needed to make them work. so, i now have RED LED blinkers in my inspire tails. no use taking pics, cuz it just don't work that way. you just have to see it in reality. just think, the only cars that have LED blinkers are the Cady DTS, Caterra, BMW z8. mercades uses them for stop lights. oh and the bus has a bunch of them, hehe.

the point was that you have splice in (Bebber please correct me) a resistor that can handle 12 ohms and at least 15 watts. this will slow the fast blinking phenomenon down. so, the LEDs are also 100% pure clear so the tail light is pure clear and then pure RED in a LED instant. the only problem is that in direct sunlight, the LED is only a RED dot blinking.

ok, im done...:o

wait, they were 10 bucks each, fit directly into the stock slot (99-01). k bye.

So this slows down the blickers but does it also slow down the hazards? I ask this because the hazards work fine with the LED bulbs, its only when you activate the turn signal that it hyperflashes.

I found a place that sells LED blinker bulbs in ANY color and each bulb has 24 LEDs . I've been dying to get them but they cost $180.

I am going to try and build something myself in the next month. 180 is a rip off but I guess they have research costs.

Yeah I know. Only blue or superwhite cost $80 per bulb. Any other color is $40. Really sucks. I hope I dont break and buy them. I'm pretty sure they emit 3 candela which is ALOT for a LED and considering theres 24 of them thats bright as hell. They have a 15 degree viewing angle which is also pretty good for a LED. This is the same place Nate got all his LEDs for his interior lights.

BTW, let me know if you do make something good.

resistor calculations

I haven't seen the led bulbs in person (yet) so I don't know what their current draw or wattage rating is. I estimated that the LED bulb is between 2-8 Watts, compared to a stock incandescent bulb of 21W. This means that to draw the same amount of total current with the LED bulb instead of the stock bulb, you need from 7.59-11.0 ohms of resistance to be placed in parallel with the LED light bulb. You use the resistor to connect the two wires going to the bulb socket together. It's always safer to go higher, so I recommend a 12 ohm resistor that's has a max wattage rating of at least 12W. Heat dissappation was a concern cause we don't want hot resistors melting wires or stuff in the trunk but Bobatimez says that they stay cool to the touch, surprisingly.

Bobatimez, you used a 16 ohm resistor with max wattage of 20W? yes?

FYI: depending on how Acura did the flasher circuit, the blinkers may possibly blink faster with a higher resistance and slower with a lower resistance.

Hmm, I'm still not sure how I solder the resistor in place. It goes on which wire? The power or ground? Since I plan on using these for my blinkers which only blink, they do not stay on, should I worry about the resistor producing too much heat? How much heat can it make if it blinks for a minute?

Heres a pic of the LED bulb I've been looking at.

Heres a comparison pic. The 24 LED bulb is on the right. I want them!

operation successful. blinks like stock alone and with hazards. very nice, no heat prob. to convert the front blinkers too, would i need to wire in more resistors?

only issue, in direct sunlight, the blinker appears to be a red dot. potentially problematic, but imo visible enough for LA traffic. i gotta say, my car is lookin so friggin HI TEC and for 25 bucks...

You connect the resistor across the two wires in each signal lamp socket. I recommend soldering bigger wire, like 18 awg, to both ends of the resistor and using a wire tap to connect the resistor ends to the lamp socket wires. So you don't need to cut any wires, just tap into them.

Yeah, if you change the front blinker to LED too, you will have to use a resistor with lower resistance to keep the bulbs blinking normally.

LED bulbs in the front housing might look funny, so give it a try first to see if you like it. Light dispersion could be a big issue here.

I'm up for that man...let's build em together...I was thinking about doing that actually. Let me know...go find me on AIM as Austin519, or shoot me an email at Austin519@aol.com, and we'll do this

bebber:
You just wiring a resistor in parallel? So the switcher circuit (blinker) is in the bulb then? Hmmm...

And about that red dot problem...NightHawkBlack, when we build them we need to build them with some serious superBright LEDs...use all the wattage in there, and give them maybe a 50-60 degree dispersion...or we could go all out...and if say we have four rings of light...we give the outside ring a 90 degree dispersion, the next ring in a 60 degree, then next ring in a 30 degree, and the innermost ring a 15 degree dispersion or so...bebber what do you think?

Thats why this company designed the LED this way.

I CLEARED THE CORNERS ON MY HEADLIGHTS, WHILE DOING THAT I ADDED HYPERWHITES TO THE CORNERS AND A YELLOW LED FOR THE TURN SIGNAL. AT NIGHT IT LOOKS GREAT BUT IN DAY LIGHT IT REALLY SUCKS. I ALSO ADDED THE BLUE ULTRA-BRITE TO THE CORNER AND HIGH BEAM. ( THIS BLINKS WHEN THE ALARM ARMS, LOOKS VERY GOOD. ONLY $15.00).
