Why does the car's high beam not seem bright enough?
2 Answers
Here are the reasons why the car's high beam may not be bright enough and the corresponding solutions: 1. Circuit malfunction: This issue may be caused by poor or loose wiring connections, or connectors not being properly seated; it requires inspection and repair at a 4S shop. 2. Bulb wattage issue: Using bulbs with inconsistent wattage during replacement may lead to this problem; simply replace them with bulbs of slightly higher appropriate wattage. 3. Reflector deformation or looseness: Deformation, looseness, detachment of the reflector inside the headlight, or quality issues causing poor light concentration or dispersion may also result in insufficient brightness or lack of focus; this requires inspection and repair at a 4S shop.
I used to frequently encounter situations where the high beams didn't seem bright enough, mostly due to aging bulbs. After prolonged use, the bulb filaments weaken, and the light naturally dims. Additionally, if the headlight covers are dirty or fogged up, the light can't penetrate properly, which becomes especially noticeable when driving on highways at night. Last time, after I cleaned the headlight covers, the brightness improved significantly. Moreover, if the battery voltage is low or the alternator output is unstable, it can also affect the light performance. I recommend checking the battery health and switching to high-quality LED bulbs for better brightness and energy efficiency. Environmental factors like rain or fog can also make high beams appear dimmer. It's best to have a technician inspect the headlight system during maintenance to ensure driving safety.
