Hey guys, 1st post, sorry if this has been posted before, but didn't see what I am looking for. I just bought my wife a 2003 LS430, and both of the low beam lights are like candles. I asked the Lexus dealer and they said that each light has it's own computer/ballast, but it is very abnormal for both lights to be dim because the computer/ballast is bad. I can't afford to take it to Lexus and pay them a grand just to fix the problem. Any ideas?
