Well, assuming that you are talking about headlights, the low beams are the dimmest settings for the drive headlights, while high beams are the brightest setting.
Your headlights turn off when you turn the high beams on because you have a defective switch. You need to have a mechanic replace the high beams switch. It is a simple replacement.
one or more headlights don't work but others do.none of the headlights will work.high beams work but low beams don't and vice versa.lights flicker and sometimes go dim.
You can't adjust high beams and low beams separately. All you can do is loosen the head light and adjust the tilt, then tighten it.
Answer: on the turning signal switch turn the handle forward for headlights. high beams pull in to flash. push out for high beams to stay on.
The switch is broken. You need to replace it.
