It depends on what type of headlight you have. What auto do you have?
Because the lights are so bright
That is normal. The dash dims so at night you are not distracted by a bright light in your face
Duct tape
rewire them.
according to Florida handsbook, you must dim your bright headlights within 300 feet of the vehicle ahead.
It is safe to use the bright [highbeam] headlights when there is no oncoming traffic/drivers who could be blinded by the bright light. Also, it is unsafe to use highbeams when there is fog or smoke which would reflect the light back to you, thus reducing the distance which you can see.
Headlights have two filaments, one for dim, one for bright. From your description it appears that one of the high beam filaments is burned out. Replace the bulb.
What are the headlights doing? Is the bulb burned out? Are the lights not coming on at all? Are they misaligned?
Low-beam headlights that are not property adjusted can make them as bright as high-bead headlights. They also can cause you to not see the full road ahead.
