Dim Car Lights? This May Be the Problem...

As bright of a city as LA is, we still have to rely on our car lights at night. Whenever our headlights start to look dim or even flicker in the slightest, it could dangerously weaken our visibility of the road ahead of us. Various problems can cause your vehicle's lights to shift. The three most common areas where the problem can usually be traced are your battery, alternator, and ground wires.



The first electrical component you should consider inspecting is the battery. Your battery could be old and need a replacement. An old or defective battery could be the cause of your dimming lights. The best way to test your battery is to have a professional do it. At West Coast Tire & Service, we have all the proper equipment and tools to test your battery for you.



The second most common explanation of faint lights in your vehicle is a weak alternator. A damaged alternator will only cause the lights to dim or flicker when the car is on. This is because the alternator charges the battery, and if it stops charging while driving, the battery will drain.

When our team tests the battery, we can check your alternator too. 



If the battery or the alternator isn't the source of the problem, then it must be in the ground wires. The ground wires, as the name suggests, serve to keep your vehicle grounded. If you have an older model vehicle, then the ground wires might come loose. If that is the case, then it could cause the lights to flicker. The blinking usually occurs when you hit a bump. If you suspect that you have faulty ground wires, then just simply inspect them. All you might have to do is tighten them. However, you could also have damaged ground wires. Over time, parts of the lining on the wire might wear off, and that could cause the lights to dim or flicker. You will have to get an auto professional with electrical experience to replace the faulty cables.
