Sorry if this is in the wrong forum, but I don't think this is a lighting issue, I think it's a mechanical one. On my 06 Honda Civic EX 2-dr - I replaced my battery about 2 wks ago. Car sat for about 5 days, then yesterday I started it up and noticed that the headlights and interior dome light would "pulsate". I never noticed this before. It seems to go away after about 20 mins of driving. It also happened this morning. What do you guys think? Weak battery? one rectifier gone on the alternator? Thanks!
