change your bulbs and see if that's it.
bad light switch.
Only high beams work on my 93 Nissan maxima. Had new headlight put in but still doesn't work. What may this be? Thanks you so much
Your high beams work but your low beams do not because the switch is broken that switches between high and low beams. Electrical switches wear out.
Possibly a defective high beam switch, or associated relay.
Bulbs burnt out (they are double filamented low beam may be burned out) Bad dimmer switch? Bad headlight switch? Bad low-beam relay?
If low beams do not work and the high beams of a Mitsubishi Eclipse do, it is probably due to a corroded connector. Simply clean the connector and add some petroleum jelly to the terminals.
Take your car in to have it checked. Turn signals should work without high beams.
First check the bulbs, if the bulbs are good I would suspect the high/low beam switch is bad.
Because there are two different bulbs for the hi-beams and lo-beams
As a guess both low beams are burnt out The daytime running and high beams are the same light filament. Or the fuse or the relay for the low beams.
check the bulb low bean burns out before high beams
