i just bought silvania cool blue bulbs. I got H7 for low beam and 9005 for high beam, when i went to put the H7 bulbs in, THEY DON'T FIT THE PLUG. The silvania bulbs have a smaller connection than my plug. and the bulbs that my dealership has been putting in are stanley, not silvania.

 

Theres a little adaptor on the end of the stock bulbs, It looks like its supposed to be part of the bulb, but it really isnt, just give it a good yank and the adaptor will come off of the bulb so you can now install your new bulbs into the adaptor. That was a really bad sentence...basically, two pieces, separate and use adaptor lol

 

thanx
