Hi, I own a Lexus es 350 from 2007 and have just replaced the lights manually myself. The only issue seems to be that once you turn the lights on there is this constant sound that comes from both lights. The sound is very obvious, I was wondering what could be the reason for this?

Thanks

What kind of sound is it. Are we talking a constant buzz or a hum or does it sound like something arching . Is it both lights and is it the HID or halogen lights . Now is it low beam or high beam or both. Just need a little more information.

Thanks for the reply. This is what it sounds like:

Thanks, the sound does not go away though.

And it won't go away until the lights go off. It is a power transformer and operates every time the bulb does
