Im new to this site and was hoping someone might have an answer to my question...I have a 2005 RX330 that I absolutely love and bought used. The only complaint I have is that one of my tail lights constantly goes out. But, it is not the bulb. I have replaced it several times, and it still happens. I eventually found out that if I give a very slight tap to the tail light (rear passenger side, located on the actual hatch, so the inner tail light), the the light will come back on and my warning light on my dash will go away. But, it eventually happens again. My thought is it must be a wiring issue, but a mechanic I took it too could not permanently fix it. Has this happened to anyone else? Does anyone have any suggestions?
