I spoke to Mark@Adirondack and he cleared everything up. I was trying to use a "regular" bulb in the H4 and it obviously didn't fit. I knew I needed H4 bulbs but I thought the regular one would fit for now just not light things up correctly.
So I ordered the other H4 and two 55/100 bulbs. I figure since I drive around in the city so much I don't need the 80/100s and everyone says that the 55/100s are very good when relayed.
Ordered a new grill as well. So I will a nice bright new lighting system soon. thanx all, Larry 91 GTI 16V At 10:13 AM 5/10/2001 -0400, Chuck Simpson wrote:
I'm a little confused on your situation. I think that in order to use the H4 headlight *and* H4 bulb, you will have to buy an adapter (9003 or 9004 i think) from the local autoparts store and replace your standard bulb adapter. I don't think you can use a USDOT bulb in your H4 headlight... it just doesn't fit. The H4 bulb will plug right into the new adapter you bought from the autoparts store. They don't usually sell *H4* adapters, since they don't really sell them around here, as far as I know. I could be wrong on that assumption. If you want to dramatically improve your lighting, then listen to what John Cadwell had to say about relays. I couldn't agree more with him! I bought two new H4 headlights, 80w/100w H4 bulbs, 55w/60w bulbs, two bosch relays, and a spool of 10awg wire. Wired everything up, and I was in complete awe when I saw how much better my headlights were! When one of my 80/100 bulbs blew, I replaced it with a 55/60w bulb. To tell you the truth, with those two bulbs side by side, I could *barely* tell a difference between the light output. Since then, my other 80/100w bulb blew, and I'm running two 55/60w's... and the road in front of me is almost like complete daylight. :) I wouldn't bother buying a brighter bulb, just because of the fact that the difference is almost negligible. Besides, the 80/100 bulbs didn't last but maybe a month. I was sort of pissed about that. Anyways... check out: http://lighting.mbz.org/tech/how_to/relays/ There is a good write up on why you should use relays, and a nice diagram on how to wire everything up. Now, all I have to do is figure out how to improve my foglights. -Chuck Simpson '92 GTI 16V (http://www.a2ipb.com/~csimpson/GTI)
