I've been having an issue with drivers side headlight working intermittently. Sometimes when I start the truck it will work sometimes it wont and if I cycle the headlight switch it may start working. The truck is a 15 GMC Sierra 2500HD Denali. 

Thanks for any help.

After market HID's with the factory projectors. They have been working perfectly for over 5 years. I swapped the HID components from one side to the other and the intermittent failure stayed with the driver side light so I don't think its an HID issue. Thanks for the reply.
