Front headlights do not work-brights work...replaced bulbs...not working again only three weeks later -2004 hyundai elantra

Alot of times with the elantra the low beam bulbs blow alot (this bulb is H7) alot of times its do to the bulb being a cheep china jobby a good brand ive found in my elantra is GE or heliolite you could also try a good HID kit for your lows

as for the highs this is the imfamus H1 bulb it hs a tendenct if breaking free from its metel base and going out of focus of your high beam reflector (try GE or heliolite bulbs there usualy pretty good)

i installed hid lights high and low on my car and i never had this problem since

i hope this helps (also make shour your bulbs are seated good and the connectors ar also seatd properly this will insure that you know there connected good)

and good luck

Use some decent bulbs and not them made in china cheap things
