I drive a 2000 cavy coupe. I wanted to change my front turn signals to blue so I removed my OEM bulbs and put in blue xenon bulbs. i turned on my lights and both bulbs work. I tried my left turn signal and it did not work (the turn arrow on my dash blinked really fast). my right one did work. I switched the bulbs around and my left one worked but my right one did not. I assumed this was the bulbs problem so I was planning on returning them. I reinstalled the OEM bulbs and started driving and noticed my CD player going a little crazy. I tried my left turn signal and it did not work. my right one did though. i don't know what the heck is going on.
