I just installed some 9007 Silverstar bulbs and like them alot but now no low beams!!! I have the setup that allows my low beams to stay on with the high beams and two relays behind each headlight for 12V. which worked fine before. Now when I turn headlights on they are really bright and when I hit the high beams the indicator comes on but no change in the lights. Does anyone have advice??? I have not tried the old bulbs back in the headlights. (They were 9004's) Thanks!!!!!!!!!

I think the wiring for the two bulbs is actually different (9004's and 9007's). There was a PDF file with the terminal wiring on here somewhere.

Thanks for the help. I wish I would have seen that before I purchased the 9007 but oh well!!!!! I will just change the wiring tomorrow! I was feeling bad for those people in front of me at night!!

After reading the above... Should I keep the 9007 and change the wiring or swap back to the 9004? I know it says it is unsafe to swap them... but the dealerships will say it is the aftermarket radio that caused the paint to chip on that 2006!!!

I'm not an expert but I do know that the focal point of the housing dictates where the filament of the bulb should be located. If the 9007's filament is not in the same spot as the 9004's then you will get LESS focused light and probably see less too.

That explains alot!!! First of all the 9007 did not seem to fit. But after a little adult language , removal of the headlight housings , and a little force the new bulbs fit just nicely!!!! The new bulb's pattern also seemed to be uneven where as the 9004's did not. Well thats that... going tomorrow to get 9004's. At least this was only a $40 mistake

So, on the sport lights what is called from the factory? I used the 9007 and 9004.
