My right tail light went out with headlights on. dash show a light showing tail lights. I bought 7440 and 7443 at autozone. when i installed new bulb. nothing. this also happened a year ago when i changed mini lights on my gear shift. when I bought them from lexus dealer they lit right up. Has this happened to anyone else? I have 2000 ES 300. any thoughts on this. Thank you very much for any info.

 

Try swapping the left working bulb with the right broken bulb, you may have a wiring issue.
