Questions that narrow it down
General checks. Answering them does not confirm the failed part on this vehicle.
Worth checking first
- A bulb, fuse, or connector can be the whole job.
- Do not treat a charging complaint as a headlight-housing failure.
Safety
When not to keep driving
- Do not drive at night without working headlights. If brake lights are out, other drivers cannot see you stop — get them working before the next trip.
