I have a 2002 Kia Spectra ls, why does the headlight bulbs keep blowing? My husband checked the ground, said it was ok. He replaced only the low beam bulbs, to see if the problem was with the high beams, but the low beams started going dim to bright. Still blew the bulbs. He straight wired directly to the low beams, but still blew the bulbs. Help..... Thanks

short circuit on the hot wire going to bulbs, also check headlamp switch and relay for short to ground.

Normally one would check in the following order.
1. bulbs
2. fuses
3. flashers
etc. So check the bulbs first... if they look burned out then replace them. Then see about the flasher if that bulbs look ok.

Good luck to you

The lights should be able to handle well over 16 volts before blowing. How often do they go out? What brand of bulb a you using. Do your headlights bounce when you drive down the road. Is the connector for the headlights in good shape with no burnt pins. Are you touching the glass of the bulb with your fingers when you install it?

ground wire broke...
try grounding the fixture with a wire or something... see if that helps.

Was the old headlamp working? if it was not then make sure that the connector from the car is clean from rust and check the wires to make sure that they are not worn out.Thank you for visiting fixya!

thinkn you got a bad ground wire somewhere or some wiring may have rubbed thru causing a short

in the engine compt there is 3 fuses. Head fuse 25th. Head hi fuse 15th. Head low fuse 15th. If these are well he verifies the cables black that are negative

hi,

you can try to see if the kias headlight wiring and assmeblies will take it. it may blow a fuse. first leave the stock headlight on for ten minutes to see how hot the composite headlight assembly gets. replace one on the passenger side with the hotter bulb and observe how hot the wires and composite headlamp assembly is getting. it it gets to hot to handle then I wouldnt do it. if its okay then replace them both, feel the main headlight wires to make sure theyre not to hot either. leave them on with the replacements for another 10 minutes, the stock fuse would blow in that time. You may have to go up 5 amps on the headlight fuses but absolutely no more. have you seen the other type of headlights HID's?
you might want to try that option as well, and I think those are are designed to replace stock installations better. use your discretion and be careful. the last thing you want is headlights using their own candlepower! lol,

HEAD LIGHT SWITCH WIRES IS SHORTING TO GROUND. OR SWITCH FAULTY.A BAD DIMMER SWITCH WILL CAUSE PROBLEMS.

If you don't have a meter or test light to confirm power, I'd try a new bulb & spray clean socket with electrical cleaner.
