Headlights and Relays

[mrein3]

Another important thing in my opinion to think about when doing headlight relays is the headlight switch you'll be saving.

Back in my shop days I replaced alot of headlight switches. All that lost voltage has to go somewhere. Where it goes is it is turned into heat which eventually destroys your headlight switch.

I use 10 gauge wire for everything between the battery and the lights. For the circuit to turn on the relay I use the stock wiring. All you're doing is converting your existing headlight switch into a relay controller.

Back in about 1985 when I installed halogen sealed beams in my '71 Monte I thought man! Look at all that light. When you get your relays installed and use those same halogens you'll wonder why people waste their money on Hellas and other aftermarket lights.

And roll your own harness.
1. It is cheaper.
2. You'll be forced to understand how the wiring works. Which is nice because then you'll know how to trouble shoot it if something breaks.
