Low Beam Headlights don't work anymore

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

ok when push the lever forward the high beams don't stay on ? then that lever should be replaced cause that's ur dimmer switch to switch between high/low beam lights if the lever is bad can surge you headlight and blow the headlights, have you check headlight bulbs its rare but it has happened that both blow at the same time

The problem will be due to a malfunctioning headlight dimmer switch and a dimmer switch connector. Also check the high beam connector.

Obviously you have a connector which has come partially apart somewhere between the Headlights and the Headlight Switch. Most modern vehicles have several connectors between the Headlight Switch and the Headlights, Start at the Firewall Connector and work forward toward the Headlights making sure all connectors are securely mated. Another remote possibility is that you have fractured the "Low Beam Filaments" in BOTH Headlights. You don't mention how hard you hit the Speed Bump but if it caused the car to "Bottom Out" the front suspension it was a hard enough impact to fracture the filaments. You can use a 12 Volt Test Light at the Sockets for the Headlight Bulbs and see if you are getting 12 Volt power there. If you are in Low Beam position you have fractured the filaments. Check with High Beam too.

I'm not sure exactly what your problem is. When you "click" your lights to low beam, your high beams should not work. But if your low beams work when you "click" them on, but your high beams don't work when you "click" them on, you either have a blown fuse, bad relay or high beam elements burned out on both lamps. (Not so unusual) Possibly a bad "dimmer" stalk switch or bad wiring, too, but a little less likely.

check the bulbs first and also the fuses theres a fuse for each side and for low and high beams, start there, good luck.

change the switch

just replace the dimmer switch under the column its wore out on the low beam side

The vehicle should not have to be running for head lights to burn.If high beams work,then the low beam head lights could be burned out,even though they light up with high beams.The dimmer switch,can be the problem if the head lights only work on high beam.

Push the lever forward to turn on high beams, if they do not work when you do this. You need a new high/low beam switch.
