Just replaced a burned out HID. When I put the new bulb in I turn lights on and blow a fuse. I rechecked install and all seems ok. Any ideas? I am trying to avoid a trip to my lexus dealer to check it out. Thank you very much.

Did you disconnect the battery when you replaced the bulb? If not, that could be your problem. Replace the fuse and see if it'll work.

Thanks. I didnt disconnect the battery. However, I tried two different bulbs and three fuses - will disconnecting the battery really make a difference? I have a lot of work on my GS just never replaced an HID.

disconnecting the battery will prevent damage to the electronic components during removal and reinstallation.

If you've tried 2 different bulbs and replaced the fuse 3 different times and they're still blowing, you have a wiring and/or ballast issue.

Is it possible that I have installed the bulb incorrectly and somehow cause a short? I had some problems with the wire clip? Anyway just asking if there are any problems like that. thank you.

Your car doesn't stock with HID.
I had the same issue with my fog light change to HID. when I left my HID on when turned on my car, it always blown a fuse.
One option is to change from 15 amp to 20 amp fuse. It solved the problem, but for a long run, people afraid it will cause some other problems.
Other option is put in a relay, I dont know the concept for this... if you find out something, let me know.
