I recently put in some hyperwhite bulbs from Modified Motorsports, and now my headlights have stoped working completely. they worked for about 4 days, then shut right off and wont turn on. the bright light dummy light is on in my dash when i turn the lights on but they wont work at all. anyone know what happened or how to fix my headlights. i checked the fuses. they are fine.

Did you change your headlight fluid when you changed the bulbs? You need to put some of the red stuff in since you got aftermarket lights now.

headlight fluid??? what... wheres that go. ive never heard of it

Are the lights still good at all? Try to put your old ones back in and see if they work.

i threw them out this time... i had this problem before, i changed to some aftermarket and they stopped working, i changed back to stock and they were fine... this time i got some good bulbs from modified motorsports thinking theyd be ok, so i threw away the stock bulbs, but im still having the same problem.

I have a feeling that you need a new headlight switch you have to watch out the higher wattage and higher heat bulbs can destroy your headlight harness and switch. go to a junk yard and see if you can find another switch. you might have to upgrade the harness for the car. I got a relay harness kit for my car so it doesnt kill my switch.
