How to Install a Turn Signal Light Bulb

Using your turn signal prevents the risk that you might cause an accident. It alerts those traveling in front and behind you that you intend to turn. Most cars and trucks today alert you automatically when your turn signal burns out. Every time that you turn on your signal, you’ll hear a rapid clicking sound that lets you know you need a new bulb. While you might think that you need to consult an expert or spend hours on your hands and knees to replace that bulb, installing a new turn signal bulb is usually pretty easy.

Front Turn Signal

Before changing your bulb, make sure you know which one burned out. You can have someone stand in front of and behind your car to look at which one no longer works. If you need a new front light, pop your hood. Look for the head light assembly, which should have a small screw or socket on the front of it. You can usually move the screw or socket to the left to gain access the light. Find the turn signal light, which should be the smallest one inside the assembly. Unscrew the old light and screw in the new bulb.

Back Turn Signal

You can usually access your back turn signal through your trunk. As with the front of the vehicle, this is likely part of the assembly surrounding the tail light. If you have an older car, you can remove the cover over the tail light. Use a screwdriver to unscrew any screws holding it in place. Some older models have a light tail light cover that you can pop off with a little pressure. After replacing your bulb, have a friend or family member check while you use the turn signal to ensure it’s working again.

Finding the Right Bulb

If you aren’t sure what size or type bulb you need, check the owner’s manual of your car. Many newer and older models use a simple bulb in the turn signal, and the 3157 LED bulb is a modern version of that bulb. Using an LED bulb extends the life of your turn signal and ensures that it’s bright enough for others to see it on dim and dark nights. Buy one bulb for your car, or buy extras that you can keep on hand for future use today.
