Hid bulb won't lock into place why?

[PTGsDaytona500GTP]

My passenger hid bulb goes in and locked when I turn it BUT for some reason my driver side will not it slightly grabs but isn't secure enough to lock! What would cause this? Could it be the bulb? Or maybe the housing on the headlight itself? Please help bc I don't want to buy a new hid kit and find out that doesn't fix it :/

Umm.. some bulbs have a little rubber "O" that goes around the base of the bulb where it locks in. It provides a much tighter fit and lock. Check to see if your driver side has it. Look at them next to each other. Try moving the passenger one to your driver side and see if it's tight or not. If the passenger side bulb is still loose on the drivers side, then I'd say it's a housing problem...

Hope this helps!!
