What is a turn signal bulb?
Some of the most important automotive lighting components are your turn signal bulbs—also known as indicators or blinkers—which tell other drivers when you are turning or switching lanes. Many cars also use these bulbs as hazard lights.
Turn signal bulbs are housed inside lens assemblies that protect the bulbs and focus their light outwards. These can be found in each of the four corners of your car. It is necessary to remove the housing assemblies to access the bulbs and replace them.
Keep in mind: It’s illegal to drive without working turn signal lights in most states.
When should I replace the turn signal bulb on my car?
Here are a few signs that it’s time to replace your reverse light bulb:
Turn signals are not activating: If your turn signals do not all flash when you activate them, one or more of them may be burnt out.
Warning light: Many modern cars have warning lights on the dashboard that indicate one of your lights has gone out. Reference your car manual to learn what the warning might look like.
Dim turn signal lighting: If your turn signals are dimly lit when activated, your bulb may be in need of a replacement.
Rapid flashing: Turn signals sometimes flash at a higher volume if they are dying. If you notice rapid flashing from one or more of your turn signals, you should have them inspected and replaced sooner rather than later.
How often should a turn signal bulb be replaced?
Like most car lights, turn signal bulbs typically last 4,000 hours or five years. If you use LED turn signal lights, your reverse light bulbs could last up to 12 years.
Pro tip: Routinely inspect your turn signals to ensure the bulbs are working. Commonly, drivers don’t realize that their turn signals are burned out since these lights are active when the driver is behind the wheel and operating their vehicle. Get a friend to stand in front and behind your car when you activate your turn signals to verify they are operating correctly.
Can I replace my turn signal bulbs myself?
Yes, you can replace your turn signal bulbs yourself, although car experts recommend that you take your vehicle to a certified mechanic for light replacements or repairs.
Your car light bulbs are prone to damage if handled or installed incorrectly, so a DIY installation could result in a shorter lifespan for your turn signal bulbs.
To be on the safe side, get a certified mechanic to replace your turn signals if they are not working.
