Here you can see the difference.

for the TL is D2R, but D2S should work too. I replaced them because mines were flickering (dying) they had almost 6 years 122k miles, I lef them on most of the time.

 

I Would say to mess with this lighting system is someone looking for a world of trouble. I agree they might look better and provide better visability, But there is no one I would trust to take those lights off and do that, Only an Acura tech, maybe. But as for the fog lights, i think an upgrade on those would be nice.

 

what's the colour temp of the RL bulbs?

 

Upgrading? It would be downgrading the superb lights the RL now has. Some people think the blue look of the 7000K and 8000K bulbs is so cool . . . I don't, but, the light output is much less than the original 4100-4300K bulbs that come from the factory. Even Halogens have better output that those bulbs!

 

I beleive it is 4300k.

 

how do you figure that yeah I'm sure halogens do for sure

 

I made the mistake of installing 7000K bulbs on my NSX. The bulbs projected much less light than the original halogens. Now I have the 4300K and the difference is like night (7000K) - and day (4300K)

 

7000K would be nice but 8000 is too blue. On the flip side, I hate bulbs that have a low colour temp (ie most indoor bulbs) as they are too warm and screw up colours of everything.

daylight is around 6500K so...

 

maybe in your situation, who knows what you did or what kind of bulbs you bought. Better luck next time. Did you buy does cheap bulbs (blue tint glass) that claim 7000k to replaced the halogen bulbs? of course they don't work. We are talking about real HID xenon bulbs that go about $100+ a set.

 

yeah many people get the 6500k, but I personally don't think the 8000k are too blue. When I bought them I had a feeling there were going to be too blue, but after the installation they are just perfect. Now 10000k and 12000k those are blue and purple.

 

It had nothing to do with luck . I installed real and top quality Phillips HID bulbs with real HID ballasts, nothing less than the best for my NSX (a touch more than $100 for the set ) - no blue tint. If all you care about is looks, then forget what I said and by all means buy the 7K or 8K bulbs. If you care about light performance, then I suggest you go with the 4300K bulb that all the engineers from Mercedes, BMW, Audi, Acura, etc. have chosen for their cars.

 

sorry, but phillips does NOT make 8000K hid bulbs.

the stock temperature rating for hid's is 4300K. meaning all cars that come with HID from the factory are 4300K. these provide the most lumens (light output). the higher you go, the more lumens you lose. with 8000k you WILL lose SOME light output, but it is still a hell of a lot better than halogen bulbs.

also, if you install HID's in a headlight casing that was originally made for halogen bulbs, the light will be dispersed unevenly and scattered. that may explain why you had such crappy output in the NSX.

here is a shot of my 8000K's:

 

Maybe I'm missing something, but what is the POINT of putting in a 7000k HID setup? Obviously it's not the light output, stock bulbs are much better, and it looks like you're using the cheapo halogen bulbs with blue covers on them. Why would anyone *want* to cheapen the look of their vehicle with blue bulbs? What's the benefit, what am I missing? And wouldn't their service life possibly be shorter as well?

personal preference. personally, the difference from 4300k to 8000k looks the same to me... in terms of light output. they are 100% real HID bulbs... no blue coating. service life is the same.

 

You are right. My 4300k were blue, but after a few minutes they turn while/yellow. I didn't upgrade to change the color, my stock ones were 6 years old, so I replaced them with the same exact bulb specs, but displays light at a different temperature. I like them a lot, because during the day they still look blue. I think they are brighter, but I'm asuming that they are the same.
