No low beam headlights, but high beams work.

Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. High beam headlights don't work or low beams don't work. The cause: A burned out bulb, or a problem with the high beam switch or relay.Dec 1, 2019

Bulbs usually don't burn out together, but it's still important to rule that out by checking for power. Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. High beam headlights don't work or low beams don't work.

I have seen both low beam bulbs burn out at the same time.
Its possible the relays have burnt out for the low beams.

It could be driving lights mode instead of low beam. Check connections.

I would check for the groundwire continuity

High current draw and bad connection at the relay, fuse box or loose ground.

1. I own a Protege and once the low beam bulb burns on one headlight the car electronics quickly cook the bulb on the other headlight as well. it is a poor design by the mfr. Pull both bulbs to make sure the low beam is not cooked.

HEADLIGHTS NOT WORKING

It can be faulty headlight switch or issue with its wiring. Or its faulty head light fuse.

These will help.

Thanks.

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.

I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

High and low beams use different bulbs. Both of my low beams blow out at the same time. Replace the low beam bulbs.
