LED or Brighter Headlight Replacement
#16
Thanks for all of the good input! I don't mind spending the money for replacement units but if I do they would need to be LED. For me I don't see a reason to buy new HID units. I guess I'll try new high & low bulbs and see what improvements that makes. I've yet to see a LED converter kit and I don't know if I'd go that route - would need to see what the kit entails.

OP: If I were you I'd try two different things.
1) Recondition/restore the headlights, assuming they're getting to look like they do in this video:
2) Assuming the HID bulbs themselves are getting tired you can always replace the bulbs by themselves.

I would *not* replace the bulb with anything in a cooler color temperature such as 5000K or 6000K. Stick with the stock 4300K. The other options look more blue-ish but they're not any brighter and the resulting illumination will have a poorer Color Rendering Index (CRI), making overall visibility less.
I would also *not* attempt an LED retrofit. This would be way more work than it's worth and LEDs aren't any brighter. They also have thermal dissipation issues - most of the LED bulbs have large heat sinks and/or cooling fans mounted on the back of them so they probably won't fit inside the stock headlight assembly anyway. The only time you see people with these bulbs is when they're running them in a stock reflector housing on a lifted Silverado or Tundra and they blind the crap out of oncoming drivers.

BTW, in reference to the Sylvania Headlight Restoration Kit I linked to above, here's how well it worked on my other car (2004 Toyota 4Runner). It didn't make them perfect but it got really close. The plastic gets yellow and cloudy like this because the factory clear coat wears off and exposes it to UV from the sun. The Sylvania kit comes with a new clear coat that you paint on to keep it protected.

Then in order to protect the plastic lens of these upgraded lights from yellowing, general debris and dust pitting the surface, or from a rock thrown from the road, I installed a clear Lamin-X headlight protection kit that I bought from Suncoast - comes with the pre-cut material to do both the large oval headlights and the for lights, which are LED versions on my car. I don't have a close-up of just the headlight, but here's one that shows the overall clarity of the front lights with the lamin-x on them.

I went with the D1S - PHILIPS X-TREME VISION 4800K 85415XVC1 HID +50% BULBS. They are supposed to change into the 5000k+ range after x amount of usage and they put out much more light than the OEM bulbs. Good call to stay away from the generic stuff; the price differential is dramatic. Ordered from hidconcept.com in Morton Grove, IL and they were very helpful.

Well I have the new bulbs but I won't have my car back until Thanksgiving.

Good for you!
I went to their engine building class earlier this year and they're great guys - so knowledgeable and willing to share it.
I'm only a couple hours from them in SC. If you'll be flying down to drive it home, maybe we can meet up.

One thing to consider is that HID bulbs change as they age. The color temperature changes and the intensity drops. It's a gradual change, but you should be able to tell the difference between a new bulb and a 10-year old bulb. Changing the HID bulbs might be a good, inexpensive first step.
Secondly, it's important not to confuse color temperature and intensity. A bulb in the white or blue part of the spectrum might look very nice and bright compared to a stock HID bulb, but the lighting performance might be worse. The human eye doesn't do well with blue light.

Very glad I saw this. I had no idea that Xenon bulbs changed as they age but in fact I took my 997.2 for its first night ride last night and the light output looks almost halogen-like. It's bright and useful but looks pretty yellow. From the front of the car they do look like Xenon bulbs but not the light output. Pelican Parts has Bosch bulbs which look decent but I can't see a temp rating on them. Anyone have a good reco for replacement? I might be inclined to go slightly cooler but not all the way to bluish 6000K -- yuck.
Also curious about the lower half of the fixture - it contains a little incandescent "flasher" bulb. Anyone tried something like a silver star replacement there?
