  1. one headlight doesn’t work. this is usually caused by a burned out bulb. if it still doesn’t work after replacing it, suspect a wiring or fuse problem.
  2. both headlights don’t work. bulbs usually don’t burn out together, but it’s still important to rule that out by checking for power. most total headlight failures are caused by a bad component like a fuse, relay, or module. wiring problems can also cause both headlights to stop working.
  3. the high beams and/or the low beams don’t work. most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
  4. headlights seem dim. if your headlights always seem dim, the problem could be foggy lenses or worn out bulbs. if your headlights seem to dim during specific circumstances, there may be a charging system issue.
  5. other headlight problems. caused by some combination of bad bulbs, wiring or relay problems, and bad switches.

in the past, many vehicle owners were able to replace burned out headlights or brake lights themselves. but with the design of today’s vehicles, headlights and brake lights are much harder to access. if you don’t own the right tools and diagnostic equipment, it is much smarter to go straight to your mechanic who understands how to inspect the headlight system, check the fuses, and take a look at the switch and relays.
