Re: Headlight Advice

Halogens and adding a relay to the low and high beams make a nice difference.

Power runs through the switch which after years can lower the voltage to the lights. Where if you use it to turn on a relay. You get a solid 14V to the lights. As most alternators run at 14V when the engine is on.
