One of the most important lights on your car is your turn signal bulb, which tells other drivers when you are turning or switching lanes. Many cars also use these bulbs as hazard lights. If you see that your bulb has gone out, it is important to replace it to ensure the safety of yourself and others on the road.
A burnt-out turn signal bulb is a common occurrence in cars. Replacing this bulb is an easy DIY fix, and usually costs under $10 to replace along with 15-20 minutes of your time.
Car insurance broker app Jerry is here to tell you everything about changing your turn signal bulb.
The exact cost varies between different Mercedes-benz models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

What is a turn signal bulb replacement?

Just as you need to change a light bulb in your house when it stops working, you’ll need to replace your automotive lights when they go dark.
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.

How to replace a turn signal bulb

Here’s how a mechanic will replace a turn signal bulb:
  • Test the turn signal lights to verify which bulb is out
  • Open the trunk or hood to access the lens assemblies
  • Remove the screws and fasteners that hold the assembly in place
  • Swap out the old bulb with a new bulb of the same specifications
  • Reinstall the unit and test the turn signals again to ensure the whole system is working
Technicians should inspect your turn signals during most routine maintenance procedures, such as oil changes and tire rotations—so it’s likely that this check will be included in your standard maintenance.

When do I need to replace my turn signal bulbs?

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.
It is also good practice to occasionally check whether your turn signal bulbs are working. While the car is in park, signal a left or right-hand turn on your steering wheel stalk, and walk outside the car to make sure both front and rear turn signal bulbs are flashing. Repeat this step with the opposite side.

How important is it to replace my turn signal bulb?

While the short-term operation of your car won’t suffer because of a burnt-out signal bulb, functional turn signals and hazard lights are important to your safety and the safety of others on the road. Be sure to replace the bulbs as soon as you are able.
