Question Wiring from H3 to 9006 <foglights>

Im trying to convert my fogs from H3's to 9006's bulbs, but I noticed something, the H3 bulb has only one single cable going to it, while a 9006 has a double cable. Im assuming that the h3's is the live and the ground is in the housing or something, I need to know if this is right,... also need to know if the wattage going through the foglight circuit/cables is the same/higher/lower than what I would need to run 9006 bulbs. Thanks a lot!!

The H3 bulb only has one wire for power. The metal disc basing is the ground return. The H3 socket will have another ground wire to plug into to complete the circuit.

9006 to 9005 conversion is easy, just cut tabs inside the plug and around the socket until it fits.

so all I would need for the 9006/5 <doesnt matter, as long as its not the h3> is to run a lead wire to it and use the H3's power without having to worry about wattage on the wires? if so, cool

i got lost in what you just said but here is what i think, they single wire that goes to the H3 is the positive on the 9005/6 bulb and what do i use as a negative??? the housing??

I guess you could do that, but on my case Im making a new housing for the back of the foglight so I would have to run a lead <neg> wire from a good ground for the neg and use the existing one for the pos

If you're just going to tap power from the 9006 socket, the H3 does have a postive and negative wire. The BULB itself doesn't not have a ground wire, it uses the basing as a ground. However, the H3 socket does have a ground return wire. So if you're going to tap power to the H3 use the two wires provided.

That will be a tough mod considering the size and geometry of your 9006-projector. I would rather spend the $200 on a pair of Hella Micro DE foglights. They'll be brighter and more functional foglights than those projectors. The money you get back from selling that McCulloch kit will more than cover them too. Better off spending less time and money and getting better results, than figuring out a way to recycle your projectors. If you're getting the retrofit done by Illusion Lighting, he's going to destroy your stock projector to use the aiming screws. Just a heads-up.

Will the new IS300 or GS300 fogilights fit in your bumper? I'd opt for the GS4x0 or IS300 foglights because that yellow-amber light matches the bluish HID beautifully. First try transplanting the yellow glass tube into your foglights and see how you like it. I'm going to buy yellow H3s because opening up my foglights was HELL. The Micro DE comes in halogen and HID. The halogen is $140 at TireRack and the HID version is $780. Here's a link:

i really want to stay away from H3 bulbs. i don't see how H3 bulbs can do what the describe it to do. H3 in my opionion are'nt the greatest bulbs used for automobile lighting. i dunno what to do yet. still deciding thanks rich.

Check wattages, the H3 is considerably less I believe. You can run the 9005/6 alot safer if you run it thru a relay (standard Bosch style). Relay ~5$ from the fog light section of your local automotive parts store.

H3 still has 2 wires (they are just very small). The bulb uses the housing as the ground and the center post is the + side. Use and Ohm meter to test the wires, cut off the connector and use the +/- factory wires to trip the relay, and run the relay to a fused lead to the battery or acc switch. If you have HID's - wire the relay to the + side of that.

Even if you do fit the H3 bulb in there. I don't think you will be happy with results. The lighting such as the lens and reflector were intended for a H3 bulb which is different. So, the photometrics were made differently. You will either suffer side effects such as hot spots on the ground as an example.

My guess is that Lexus that do have H3 bulbs are meant for fog so, the beam will be dispersed in wide spectrum so, even if you do make them brighter. It will be not that noticeable or miniscule. Outside though, people may notice but again. It may cause glare which, fog lights are not suppose to do. That is because you are using a different bulb that it was never intended for. If you do it with a different bulb that was never intended for that use. It is anybody's guess.

The bulb from H3 is 55 watts just like the 9006 even though the amount of Lumens may or may not be more than a H3 bulb. Go to a automotive lamp forum like, Philips automotive lighting forum. They can explain probably better than I can. A few suggestions would to put a supplementary fog light system , a H3 Xenon bulb but, with the same stock wattage, and/or a bigger gage wiring to the H3 bulbs.
