Not yet, but there is a little gerbil tunnel in the foam that the mechanic used to access passenger bulb. He is skinny and little. If that bulb goes out, I will let him do it during my annual visit there.... I can't even get my hand in there due to the foam.

Wonder if there is a solvent that will eat that foam? I know heat will but that can be a little risky. Maybe one of those wheels you use in a die grinder with the 1/2" long little green fingers would take it out without hurting other stuff.

I saw it on the Internet. It MUST be true...

Depending on the type of foam plain gasoline will break most foam down

Chessie, those H4/LED bulbs that you posted the links for look like a superior design to me. The key thing being the locating of the emitters as closely to the position of the original filaments as possible. Due to the 3 dimensional nature of the filament, the 2 dimensional emitters, and the larger size it'd be impossible to get the same crisp characteristics and the pattern is going to be a little fuzzy around the edges but the light will mostly go in the right place. How the brightness compares is largely a function of the emitter size and it may never reach the intensity of a 120 or 150 watt Halogen but that's at the high end anyway. Aside from that, the configuration is actually pretty good and the price is fairly reasonable.

here is an example led bulb for hella 4x6 lamps that take this h4 type bulb.

they come with h4 halogen bulbs which are 12 volt. check for h4 led bulbs rated for 12 to 30 volt from a led bulb outfit. many are available through Amazon, along with hella headlamps. you can peruse the hella site also. their lamps are sized in metric but convert to inches. 164x103mm
I went back to review these links. I like the prices. LOL
So i have the old school round lights with no swappable lights. I'm thinking of getting one that has replaceable lights and made for halogen so the beam focus hopefully works alright. It does not have to be precise like some here getting into the tech and optic topics. I just need light so i can drive at night.
Going to wonder around the local pik-and-pull for headlights.

just buy round hellas and pull filament unit and install led. if you are 24 volts, buy the led bulbs rated for 12 to 30 volts. as far as output, i use 12k per pair for fogs bulbs and high beam bulbs. they work great here at night, as we have a lot of deer, infact just missed one about 2 feet in car other night. bulbs saved the hit. they sell led bulbs up to 20k per pair, but i wont go for that bright; too expensive and suspect shorter life.
some of the leds are rotatable to adjust your pattern. many high output bulbs have finned a heat sink on them to keep bulb cool. mine have a little cooling fan. i thought pretty hokey, but have had them for 3 years now and fans still working. haven't had a bulb burn out yet either. have them on 3 different vehicles. use a color temp of 6 to 6500 k to get pretty pure white. higher k, and color starts shifting to blue lower shifts to yellower light. think of flourescent tubes in warm white, cool white, daylight to give you an idea of what im referring to.
you have to experience 12k/ pair fog light bulbs, adjusted so as not to blind oncoming drivers. youll love them.

I just spent 2 1/2 hours with a Mother's headlight buff kit. Amazing results. I have mostly used Maguire's products, but this was rated better and since my Father in Law swears by Mother's, I gave it a try. My wife hates Mother's because when she was about 10, she and her 3 sisters were each given a wheel on his 4106 to buff. Hand rubbed Mothers.....  She still has bad dreams about it

Anyhow, it cleared the lens and I can see my bulbs again. Test drive tomorrow evening when there are few people on the road.
Thanks for all the help and ideas but since my passenger headlight would have been such a nightmare to pull, and for how little I plan to run after dark, I'll see how this worked.
