I have an after market HID kit installed. The right bulb comes on everytime, but my left one takes a lot of coaxing to get to come on. I've seen the left one come on for a moment and then turn off. Eventually, after turning the lights on and off about 10 times, I can get it to turn on. The right bulb lights each and every time. It's been doing this since I installed the kit over a month ago. Would this be a problem with the left side or is this type of thing normal? Thanks.
