With the longer days of summer, many people may not think about their headlights and brake lights. However, make sure you keep an eye on them as they can burn out or stop working without you noticing. It’s still important that you have working headlights and brake lights so that you can be seen on those unexpected rainy days or for late-night driving.
So what causes your headlights to not work or seem extra dim? There could be several reasons, including:
- Burned out bulbs: If only one headlight is not working, the problem is typically a burned out bulb. Have it replaced as soon as possible and then if it still doesn’t work, you will want your mechanic to check the wiring or fuses.
- High beam doesn’t work: If the bulb isn’t the problem, it could be faulty wiring in the switch or relay.
- Electrical System: If the lights dim only when the engine is idling and the brightness changes with the RPM, the problem may have to do with the electrical system. This could involve a problem with a bad alternator or a loose belt. If the alternator is fine, the accessories may be drawing too much power, such as aftermarket components (like a custom sound system with a powerful amplifier). In this case, a more powerful alternator may take care of the problem.
- Lights seem dim all the time: The problem could be foggy lenses or worn out bulbs. Over time, bulbs can lose their brightness so you may want to invest in a new set of bulbs. Dirty, foggy, or oxidized lenses block the light. Dirt is easy to clean. Foggy lenses are an indication that water is getting into the headlight assembly. It may need to be replaced. Lenses that have oxidized can be reconditioned. This involves removing the oxidation and then applying a protective coating.
In older model vehicles, the average person could replace burned out headlights or brake lights themselves. But with the design of today’s vehicles, the lights are much harder to access. Unless you have the right equipment, it is much smarter to go straight to your mechanic whohas the right tools and diagnostic equipment to inspect the headlight system, check the fuses, switches and relays, and then either repair or replace as needed.
