I have a 90 CRX (DX) & at night when I turn on the lights there so dim even when the brightness is all the way up , & every once in a while all the lights will suddenly start getting real bright but when I slow down the lights all get dim again but as the RPMs go up it gets brighter , but most of the time it just stays dim .. can someone help me out ? im tired of barely being able to see the road & the gauge at night .. thanks !!

 

Its your battery! It has such a low charge that when you are driving and ur rpms go up, the lights go to where they are supposed to be at. When the rpms drop, the brightness drops with it. Go to your local Kragen, or auto zone or parts store and see about gettin ur battery tested. Chances are you just need to re-charge it...but, you may need to replace it if the charge has been that low for a while. Also, have them check your alternator to make sure it is charging your battery the way it is supposed while your driving. Hope that helps...have a good one.

 

deff. sounds like your alternator as the rpm's increase the belt spins faster and gives battery more charge? either or check both, that should fix your problem, and if not...your brightness control is broken somehow
