My wife has had her 2000 RX 300 about a year now and she is very satisfied with it. One strange thing I've noticed about it is that when the engine/electrical system is cold [ from a cold-start ] the lights seem to have a " FLICKER " . Just about all of them; headlights, interior lights, etc. It's hardly noticable until I mention it to someone else. My neighbor has a 2000 RX 300 also and it does the same thing. Is this this just a peculiarity with Toyota and Lexus?

 

We have a 99 and all of the lights flicker on it also. Charging system checks out perfectly and is has new Interstate battery but no change. Let me know if you find out if it is normal or something wrong. Could it be a short??
