JC Whitney 7" Headlamp Conversion?$45.99
This diagram might be easier to read:
BTW: Those JC Whitney H-4's with the clear lenses are VERY annoying to on-coming traffic. The flat lense Hella's or Bosch units are fluted, which means the beam is concentrated to aim forward and away from on-coming traffic. Those JC jobs are like powerful fog lamps... NOT a good idea.
I just bought a set of used Bosch H-4 headlights from a Porsche 928 on e-Bay. I paid $26 with shipping.
They even have the neat parking light in the base of the lamp....
That little bit of corrosion on the back will never be seen, or affect, the lamp's performance. I have a set of these in my Dart and the difference is amazing.... and wiring in the relays took me all of 45 minutes. The relays I bought at Radio Shack for a few dollars each. Just make sure you buy a 30 AMP relay for each circut to prevent them from melting.
