Dim Lights At Idle

I read a post somewhere that you can eliminate dim lights at idle by installing relays to the headlights. For some reason the old Chrysler cars had wiring issues and the lights would dim at idle even on cars equipped with alternators. For example, the voltage at the battery and also the battery post on the back of the alternator may be in the 12-14 volt range but the voltage at the headlights would be less. This was because of the alternator, wiring, connections, headlight switch, dimmer, etc. The lights would brighten to normal as engine speed increased.

I installed 2 fused relays (1 for low beam and 1 for high beam) and now the headlights get their power directly from the battery. The voltage now travels a much shorter distance and passes directly from the relays to the headlights. Nothing else to interfere or draw current flow. It works beautifully with my factory headlights and can't wait until I get a pair of Sylvania Silverstars to really brighten things up.
