Your car's tail lights play an important role in signaling the presence of your vehicle to other motorists. It is important that you regularly check the functioning of these lights to avoid potential problems. They can fail for several reasons, including cracked lenses, broken wiring, and faulty bulb filaments. Regular checks will help you detect a problem early and make the appropriate repairs. Changing tail light bulbs is an easy, quick and inexpensive procedure.
Historically, tail lights have used incandescent bulbs with reflectors. These reflectors used pillow-type optics, which create multiple images from a single light source. This led to deep, non-uniform tail light designs. Fortunately, technological advancements have resulted in LED tail lights that are uniform and less obtrusive.
Tail lights are essential automotive parts. They emit a red light parallel to the rear of the vehicle, alerting other road users to your vehicle's position and speed. If your tail lights go out, you must repair them as soon as possible to avoid causing an accident. They are an important safety feature that should never be overlooked.
Your car's brake and tail lights are separate, but sometimes they share the same bulb. While this is common, there are some vehicles with separate bulbs for each circuit. If you're unsure, ask an assistant to press the brake pedal, and they'll be able to tell you if your brakes and tail lights share the same bulb.
