What to Do When Car High Beams Don't Work?

Solutions for car high beams not working: First, check the fuse box to see if any fuses are blown. Then, inspect for any faults between the car light switch and the dimmer switch. If issues are found, proceed to a nearby repair shop for further inspection and repair. When using a screwdriver to connect the dimmer switch's live wire to the high and low beam terminals respectively, if the lights turn on, it indicates a fault with the dimmer switch. If the high beams don't work, check whether the high beam indicator light is on. If it is, the fault lies between the terminal block and the headlight; if not, the issue is between the terminal block and the dimmer switch. If only one headlight works while the other doesn't, it may be due to a burnt-out filament, an open circuit in the wiring, or poor grounding causing weak headlight brightness.
I've encountered the issue of high beams not working several times recently. As someone who has driven for many years, the first step is to check if the bulb is burned out, which is the most common cause. Bulbs tend to age and the filament can break after prolonged use. Next, check the fuse located in the fuse box in the engine compartment. Find the one labeled for the high beams, and if it's blown, replace it with a spare fuse. Last time, after replacing the fuse in my car, the high beams still didn't work, and I discovered that the relay contacts were corroded, so I had to take it to a repair shop. If you encounter this problem while driving at night, never force the high beams to work. Instead, switch to low beams or use fog lights for assistance, and pull over to the side of the road for safety. Regularly cleaning the lamp covers and checking the wiring can effectively prevent such failures. After all, lighting is crucial for driving safety and should never be neglected.
