Why is the car's high beam not working?

[StCalvin]

High beams emit parallel light at their focal point, which is more concentrated and brighter, allowing illumination of distant and high objects. The reasons for a car's high beam not working include: lighting circuit failure, burnt high beam circuit, blown high beam fuse, damaged high beam switch, or disconnected/poorly connected wires. Specific causes are as follows: 1. Lighting circuit failure: Poor or loose connections, or improperly seated connectors may cause this issue. 2. Burnt high beam circuit: Using bulbs with mismatched power ratings may lead to this fault. 3. Blown high beam fuse: Check if the fuse is blown and replace it if necessary. 4. Damaged high beam switch: If the circuit is intact, the switch may be faulty and needs replacement. 5. Disconnected or poorly connected wires: Remove rust from connectors or replace the wires.
