What are the reasons for car high beams not working?
1 Answers
There are several reasons why car high beams may suddenly stop working: 1. Circuit failure: Poor or loose connections, or connectors not properly seated. The wiring needs to be inspected to ensure complete circuit continuity. 2. Incorrect bulb wattage: If the replacement bulb has inconsistent power specifications, it won't function properly. Replace with a bulb of matching wattage. 3. Reflector (headlight) aging/cracking: Prolonged usage can cause failure or insufficient brightness. This requires headlight replacement. 4. Deformed reflector mesh: Internal quality issues causing reflector deformation necessitate headlight replacement. 5. Incorrect beam alignment: Refer to the vehicle's user manual for beam adjustment procedures to correct this. 6. Poor headlight sealing: Long-term use or quality issues may cause seal failure, allowing water, debris, or dust ingress that obstructs the beam. Requires disassembly and cleaning; if ineffective, replace the headlight.
