Looks like LED replacements are now made for my 4x6 inch truck head lights.
Must be fairly new, tried searching for such an item about a year ago and could only find the larger 5x8 inch truck lights.
Says they have low beam and high beam. The ones I am finding for sale say they are made of 15 LEDs, 3watts each, 3200L high beam and 1500L low beam. Looks like they draw 3 amps on high beam and around 1.5 amps in low beam.
I will order a pair and test them to see if there is any possibility they can be used as a low beam. That way if not, I can install them into the high beam sockets and use them as high beams only.

Mine is a '96 Accord.
The beauty of a projector retrofit is that the light output, beam pattern, and cutoff are the same no matter what car you fit them in because the whole projector is swapped. The lights themselves don't care what car they're on. It's more work baking apart your headlights and epoxying the new projector, but should be worth it. I've had 18w drop-in bulbs in my halogen projectors for a year and a half now and have gotten tired of the poor light output, especially highway driving at night.

I thought I had, but apparently not. It's now on a list.

It wasn't good, just better.

Thanks all, for your input.

I ordered the kit.
I'll post back once it's installed, with photos of the beam pattern.

My primary aim here is to reduce amps draw on my alternator-deleted, battery-supported electrical system. At 3.2 amps vs. 8.x amps for halogens (totals for two bulbs), this will very nearly triple my available run time for headlights.

After a careful reading and rereading of the specs I expect a good improvement in brightness also. These are supposedly 2000 lumens per "bulb", vs 1000 for standard halogens. Improvement will be easy to verify or disprove, once it's installed.

I am adding this to the LED wiki.

As promised, here's a photo of the lighting from the LED "bulb" vs a standard halogen.

Bear in mind, this car takes two separate bulbs for high and low beams. Four bulbs all together. My point is, because the low beam bulb shown here is dedicated for low only, it's easier to deal with the optics when trying to get the beam pattern right. I would not expect nearly as good a beam pattern in an LED "bulb" that provides both high and low beam.

Each of these "bulbs" is rated 20W and 2500 lumens. That's' vs. 55W and 1000 lumens for standard halogens. The added brightness is due to the fact that LEDs are a much more efficient producer of light than halogens.

Looks like the pattern is pretty good.

looks REAL promising. pics of the road, distant signs?
the original housing was used, correct?
one more, is the braided heat-sink aluminum or stainless?

XenonDepot says the heat sink is tinned copper.
Yes, I used the original Accord headlight reflector housings. I polished them a couple months ago so the lenses are reasonably clear.

No other photos quite yet. I've been using Photobucket but it doesn't want to play nicely with my iPhone, even when using their updated app. So dealing with photos has become a PITA, sorry to say.
