does someone know why my xenon HID light bulb wont fit into my scion tc..... when l bought the kit.. it say its for scion07... but when l use it... everything work .. however when l try to twist in the light bulb to lock it.. it wont lock... l had to use tape and tape it up so it wont pop back out.... so ghetto....does anyone have similar problem?

thats aftermarket for u..

Technically, HID kits are illegal for road use, since the headlamp capsules were not rated by the NHTSA for HID bulbs. The reflectors are setup differently, and you could blind oncoming drivers.

But since nobody takes that advice. Be careful of where the openings for the bulb are, it will only fit in one way, otherwise it wo not sit straight into the opening.
