I was thinking of doing this to my car as well. Just curious to know if you had do any special wiring for them to go in. Would love to see some pics with them turned on. Where did you get them from?

What brand of lens did you go with?
I am trying to find the best quality one, that can handle a 100/80 bulb (but I think they all max out at 60).

Not sure of the brand, they have japanese writing all over the box. I paid $40 for the set from a friend who ordered them for his Talon, but they were the wrong size.
They sell them at ProCarParts.com I believe for $23+shipping (they charged $15 for shipping).
The bulbs have the same plug pattern as the stock bulbs so no re-wiring was required. bulbs are either 55 or 60/100.
There is also a second bulb in the housing, a small blue one which I didn't wire up, gives the lens a blue glow when the lights are off.
I need to aim my headlights since they are way off. I'll get some pics of them lit up again, the ones I took were too blurry since I wasn't able to get an angle and hold the camera still, may just use a tripod like I should.

here is a pic of the lights on,

I was going to wire up those small lights to a small relay and then to a switch.

Bristol, whats the scoop on your harness construction. iv heard for them to actually work correct a upgraded harness is needed as our stock harness dosent provide the correct ampreage .

I originally just changed the way the wires sit in the connector housing cause the ground and power are different on the H4 bulbs vs. sealed beam. I then read that the increased load wrecks havoc on the stock switch and also read that adding relays prevent damage to the switch and add up to 15% more power making them brighter. I just put in a harness with new connectors...heavier wire and 2 bosch relays....in my cas its made a noticable differance....especially with the high beams on. Im talking to my buddy who helped me about making a kit with the harness completed with the relays...so itll be a very minmal install effort...and might sell a few on ebay if we can get them assembled for a good price.

i wanted to buy those, i think they look sweet but with the camaros you need 4 and only getting two looks very out of place since they give the headlamps a VERY different look. can you hook up the brights as well like the low beams??

mine are glass. I dont have that silly little blue LED light bulb in the bottom of mine either. i will have to check and see what brand they are.
How do you hook up the brights for the camaro with only 2 prongs do you buy new connectors? I actually like the blue led lights also they look cool at cruise in's with the car sitting there and a bunch of blue lights lit up but my car is blue also.

On mine, the outer lights do everything. The inners have bulbs in them, but the connectors are not hooked up. I am working on a harness that will let the inners work too, but I have many more important projects right now..... 2 of them to be exact.
i did em a while ago on my camaro
here is the DS all h4's, projectors on the outside and euro's on the inside... there now swapped to projectors on the inside and euros on the outside... im very happy with the euros but disapointed in the projectors as they are not real focal projectors... but when teamed with a high wattage bulb they emit an insane amount of light not realy focused. all the stuff was purchased from matrix racing. and i made the harness myself... overall excellent lighting over the stock setup
