Could be bad bulbs (double filamented) or bad dimmer switch
yes my brother has done it on several Chevy vehicles with that style head lights
Check fuses, common circuit
bad fuse or relay switch
May have to be turned off manually Auto sensor bad
When you have your head lights turned on (the switch turned to the right all the way), pull that same switch out towards you
Bulbs burned out? Headlight switch bad? Relay?
yes, if truck has day running lights, the low beams are on at all times, when head lights are turned on by the switch, the voltage is increased on low beams to a full 12 volts on low beam, when switched to high beam, all four are on.
Break lights come on when you step on the break, they do not come on when the head lights are turned on.
High and low beams have differant filaments. You have to replace the bulbs.
it is most likely that it is a relay if both your tail lights and your dash lights are not turning on when your head lights are on, because your head lights run off of their own fuse it is most likely that it is a relay if both your tail lights and your dash lights are not turning on when your head lights are on, because your head lights run off of their own fuse
Brake lights should NOT be effected by the headlights. Brake light function is completely independent of the headlights. Assuming you are not refering to the tail lights, or marker lights, which are supposed to come when the head lights are turned on. Not having brake lights when the head lights are on is a big safety problem and should be corrected.
High-beam lights are your sencondary head lights in any veicle. They can usually be turned on with the same botton you use to turn your head lights on. High beam lights are use to see farther and wider in dark areas.
