BMW 525i Fog Lights
Fighting the Fog: Troubleshooting Your BMW 525i Fog Lights
Driving through clouds of fog or sheets of rain is suicidal if you're not armed with properly working BMW 525i fog lights. Bad weather and difficult driving conditions can give you poor and limited visibility on the road that can greatly jeopardize your safety. To avoid accidents on the road, your fog lights should always be in good working condition. However, their location at the front end of your vehicle makes them highly susceptible to damage. Harsh outside elements, as well as faulty wiring and burned-out bulbs, may cause your fog lights to malfunction over time. When this happens, you'll be left at the mercy of your headlights. Brace yourself for a possible accident or road mishap, though, because headlights are practically useless in foggy weather given the kind of beams they project. So if you're noticing problems with your BMW 525i fog lights, do some troubleshooting right away to spare them from total damage. Here are a few tips to help you out:
Faulty switch and burned-out bulb
If you're experiencing difficulty activating your fog lights, the problem may lie in the switch and bulb. When these two components malfunction, your fog lights will cease to work properly. In most cases, the fog light may not even turn on and function at all no matter how many times you activate the switch. A voltage tester or a voltmeter can help you determine whether the switch and the bulb are both receiving electricity. The voltmeter will show a reading if they're both working fine. No reading means the switch and the bulb are faulty, so you need to do the necessary replacements. Also, check on the bulb's filaments for possible breakage. A bulb with broken filaments should be replaced right away.
This is also one of the main causes of fog light failure. In most cases, all you need to do is to replace the blown fuse to restore power to your fog lights. But before replacing the fuse, you must first test it using a voltmeter. Like with the switch and bulb, zero reading means the fuse has gone out. Get a replacement right away to prevent fog light problems in the future.
