Re: RE: Re: 12 or 24 volt M37 Actually they're close enough that a single resistor will do the job as it has for me many times in the past. You have to remeber typical voltages vary greatly in a vehicle. Headlights as well as many automotive elements that are primarilly resistive are very...

Re: 12 or 24 volt M37's Just now caught your question. Yes a resistor in each ground leg of the headlights. Typical headlights have three posts or connectors, one being the dims or low beam, and the second for the high beams or brights. They share the ground or return leg or post internally...

Re: Series or Parallel, To Be or Not To Be That and some wire and connectors. Disconnect the ground wire from the harness at inside fender well from one of the headlights, connect your wire to the ground wire from this headlight and run it over to the other headlight. Disconnect both the high...

Holy Toledo! Wait a minute. A much more important issue is who is the hood ornament on that truck????????? OOOH MY GOD, and where can I get one?

Series or Parallel, To Be or Not To Be No, unfortuneately you can't. you can on single element bulbs but because the headlight has two elements that go to one ground internally there is no way run two wires to one headlight and then run those two separate wires over to the other headlight and...

Ground Legs Yes, one in each of the ground legs on the headlamps. Normal headlamps have three wires or connectors. One is a ground or common for the low and high beam elements. For other bulbs that may use the body or housing for ground to the frame you would have to use a resistor for each...

12 or 24 volt M37's What a subject. First, lets discuss hooking up a 12 "Load" to just one of the two batteries that make up a 24 volt system. Bad Idea. When you use just one of the batteries which are in series, you drain one more than the other. The 24 charging system (which actually runs...
