First, be sure the high beam bulbs and fuses are good. From there I would suspect the high/low beam switch is bad or out of adjustment. Really need the year, make and model to add further possibilities.
Could be a fuse fault, switch fault, or wiring fault.
Make sure the bulbs are okay, then check the dimmer switch.
It is probably the dimmer switch. The contacts in the switch will get pushed back and when you switch to dims they will not touch. Had the same problem on my 91 Nissan.
On my 2006 you pull out on the end of the turn signal, they will not come on if your brights are on, only works with dims.
You need to replace the bulb in your lights. The dim lights and bright lights have different bulbs.
if your dims work, but brights don't then it's probably your high beam switch.
Check to see if the foglight switch is on. Brights (high-beams) are automatically disengaged when fog lights are being used.
what about the brights?
Same reason morons can reproduce without a permit.
could be headlight fuse or headlight switch.
