Driving with your tail lights off at night is not only dangerous, but also illegal in most states. It can reduce your visibility to other drivers, increase your risk of getting rear-ended, and result in a hefty fine or even a ticket. But how can you avoid this common mistake, especially if your car has a light sensor that automatically turns on your headlights when it gets dark?
The answer is simple: check your dash lights. Your dash lights are the indicators on your dashboard that show you the status of various functions and systems in your car, such as your speedometer, fuel gauge, engine temperature, and warning lights. They are also connected to your tail lights, so if your dash lights are on, your tail lights are on too.
But what if your dash lights are flickering, dim, or not working at all? This could mean that your tail lights are also malfunctioning, and you may not even notice it until someone alerts you or you get pulled over by the police. There are several possible causes for this problem, such as a loose or corroded battery connection, a faulty alternator, a bad fuse, a damaged wiring harness, or a defective light sensor. Here are some tips on how to diagnose and fix these issues:
– The dashboard lights in your vehicle flicker, which could be a sign that the battery is not supplying adequate power to the electrical system.This could be due to a weak or dying battery, a loose or corroded battery terminal, or a faulty alternator that is not charging the battery properly. To check your battery, you can use a voltmeter to measure the voltage across the terminals. If your battery is low, you may need to replace it or jump-start it with another car. To check your alternator, you can start your car and measure the voltage across the battery terminals again. If your alternator is bad, you may need to replace it or have it repaired by a mechanic. To check your battery terminals, you can inspect them for any signs of corrosion, dirt, or looseness. If you find any, you can clean them with a wire brush and tighten them with a wrench. You can also apply some dielectric grease to prevent future corrosion.
– The lights on your dashboard appear dim. it may suggest a blown fuse or a damaged wiring harness. A fuse is a small protective device that prevents electrical system overload by interrupting the circuit when the current surpasses a specific threshold. A wiring harness is a bundle of wires that connects your electrical components to your power source. To check your fuse, you can locate the fuse box under your dashboard or in your engine compartment, and look for the fuse that controls your dash lights and tail lights. You can use a fuse puller or a pair of pliers to remove the fuse and inspect it for any signs of melting, burning, or cracking. If the fuse is blown, you can replace it with a new one of the same amperage. To check your wiring harness, you can follow the wires from your fuse box to your dash lights and tail lights, and look for any signs of fraying, cutting, or melting. If the wiring harness is damaged, you may need to repair it or replace it with a new one.
– If your dash lights are not working at all, it could indicate a defective light sensor. A light sensor detects ambient light levels and automatically turns on headlights and tail lights when it gets dark.To check your light sensor, you can locate it on your dashboard or near your windshield, and cover it with your hand or a piece of cloth. If your headlights and tail lights do not turn on, your light sensor may be faulty. You can also try to adjust the sensitivity of your light sensor by using a knob or a button on your dashboard. If your light sensor is defective, you may need to replace it or have it repaired by a mechanic.
To avoid driving with your tail lights off at night, you should always check your dash lights before you start your car, and make sure they are on and working properly. You should also check your tail lights periodically, especially if you notice any changes in your dash lights or your light sensor. If you find any problems with your battery, alternator, fuse, wiring harness, or light sensor, you should fix them as soon as possible or take your car to a professional for service. By following these tips, you can ensure your safety and avoid getting into trouble on the road.
