BMW 740i Fog Light: Typical Problems and What to Do When They Arise
Your BMW 740i is equipped with fog lights to help you see better whenever the weather is too foggy or misty. However, even though these lights are designed to last for a long time, they eventually get damaged because of various factors. Once this happens, they will cause problems that can seriously compromise your safety. Listed below are some of the problems that you may encounter with your 740i fog lights.
Glaring fog lights
If other drivers are frequently honking at you especially if they are driving towards you, then you'd better make sure that your fog lights are aimed properly. Sometimes, due to driving over potholes and minor collisions, these lights come out of alignment. If this is the case, you must aim the lights with the help of a tape measure and a marker. However, before doing this, make sure that your BMW 740i has at least half a tank of gas and is carrying its usual weight.
Flickering fog lights
Due to constant use, the fog lights of your 740i may eventually get damaged. One surefire sign that this is about to happen is when the lights are flickering all the time. To solve this problem, you need to use a voltmeter to check whether the root of the problem is the switch or the wiring. Once you diagnosed the problem, replace the faulty part immediately to avoid causing more damage to the fog lights.
Dim fog lights
Your BMW 740i fog lights will become too dim sooner or later because of every day use. Once this happens, you won't be able to see well if the weather is too harsh, so your safety will be compromised. As a solution, you should replace the fog light bulbs immediately. Fortunately, this is relatively easy and can be done at home especially if you have replacement bulbs on hand. Just make sure that bulbs you have match with your vehicle's make and model.
Hazy fog lights
Another problem that you may encounter with your fog lights is having hazy lenses due to dirt. Luckily, solving this problem is easy, and you don't have to spend a lot to do so. Just prepare denatured alcohol, a putty knife, and car wax. However, be careful when using the alcohol because it can damage your vehicle's paint job.
