Headlights

busted knuckles said

I was driving my dart tonight, I had the revs up fairly high and my headlights got quite abit brighter. I have never noticed this before. What could the cause be? I tried to mimic this in park, with the rpm up, but did not do it. Thanks for any replies.

I don't know what year your car is but I have a 67 Barracuda and it had the old style alternator and voltage regulator. I had the same problem with my car and decided to do something about it. I changed the entire charging system to a 75 charging system. The alternator is putting out 80 amps opposed to the old 35 amps now. My headlights stay at a constant brightness at whatever RPM of the motor and of course a lot brighter now. I also bypassed the amp gauge under the dash and upgraded my wiring to larger wire. Check this out and perform these tech articles and you will have a healthy charging system and nice bright headlights.
