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.

Blown fuse

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.

  • Top Tips in Maintaining the Good Condition of Your BMW 525i Fog Lights

    You may not pay much attention to your BMW 525i fog lights under good weather, but they're actually your only source of hope under foggy conditions. These lights cut through clouds of fog, sheets of rain, and heavy snow to provide you with maximum visibility that will allow you to pass through the mist safely. Without these lights, the risk of getting into a serious road accident increases. Dirt, moisture, and other damaging elements may affect the fog lights' performance and cause them to malfunction over time. To prevent fog light problems, you need to perform regular maintenance and routine inspections. Keeping your fog lights in tiptop shape will not only ensure your safety on the road, but it will also cut you back unnecessary replacement expenses. Fog light maintenance does not require the help of a professional auto detailer or mechanic. Here are a few things you can do to preserve the good condition of your fog lights:


    Clean your fog lights regularly.


    As with all auto accessories, cleaning your fog lights is a must if you want to achieve optimum visibility. Fog lights naturally become hazy or faded over time, and this process of oxidation causes their brightness to diminish significantly. When left disregarded, they may even become a safety hazard. You can restore the condition of your fog lights by simply cleaning and polishing it regularly. Denatured alcohol and a simple home solution like toothpaste can help remove the haze from your fog lights. For hard-to-remove dirt and debris, scraping them off with a plastic flat-edged knife will do the trick. Standard car wax, which can be bought in most auto supply stores, can help bring back the shine of your fog lights.


    Use the right bulbs.


    Your fog lights won't work properly if you're using the wrong type of bulbs. This can lead to total fog light failure that may require you to replace the entire assembly. To achieve optimum performance, make sure you use bulbs that are compatible with your fog lights. This will largely depend on the type of fog lights you have, so consult your vehicle manufacturer first before purchasing a replacement.
