How long does it take to replace a turn signal bulb? It typically takes .50 hours for a certified mechanic to complete the job. Your mechanic will inspect your turn signal lights to determine if a replacement is required, then follow through with the replacement procedure. 

How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my turn signal bulb replacement and how much do those parts cost?

You can check your owner’s manual or ask your mechanic for specific information on parts and tools for your turn signal bulb replacement, but here’s a general rundown:
  1. New turn signal bulb: Based on your vehicle’s specifications, the main part for this replacement will be a specific type of turn signal bulb. You can check your vehicle’s owner’s manual, ask a mechanic, or visit an auto parts store to find the right bulb for your car. Turn signal bulbs typically cost $10 to $20. 
  2. Dielectric grease: Mechanics typically use dielectric grease to secure your turn signal bulb in its designated bulb socket and prevent corrosion. Dielectric grease costs $7 to $30.
  3. Screwdriver: To access the light housing for your turn signal bulb replacement, your mechanic will need to remove bolts or screws with a screwdriver. Screwdrivers can cost as little as $10, but full screwdriver sets can reach up to $100.
  4. Gloves: The oils on your hand can damage your car lights and reduce their lifespan. For this reason, you or your mechanic will need to wear protective gloves when replacing your turn signal lights. Mechanic gloves cost $35 on average.
You can purchase turn signal bulb parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto. Three brands we recommend for turn signal bulbs are Philips, Sylvania, and Wagner. For dielectric grease, brands like Permatex, CRC Industries, and Super Lube are amongst our top recommendations. However, keep in mind that the best parts and brands for your turn signal bulb replacement will vary based on your vehicle’s year, make, and model.
Pro tip: If you are getting your turn signal bulb replaced, you should also request an inspection for your other
headlight bulbs
tail lights
, including your parking lights, brake lights,
reverse lights
, and
trunk light
The best choice will depend on your vehicle and bulb type, but aftermarket bulbs are typically used for car light bulb replacements. While OEM bulbs can sometimes be more durable, aftermarket bulbs are highly accessible, typically more affordable, and offer multiple options.
Your best option: Opt for aftermarket LED light bulbs. LED bulbs are typically brighter than OEM halogen or incandescent bulbs, they last much longer, and they are easy to install.
You can buy new OEM turn signal bulbs directly from your vehicle’s dealership, or from an auto parts store that sells dealership parts. Auto parts stores, like AutoZone, NAPA Auto Parts, and Advance Auto Parts, also offer aftermarket parts, and you can also buy replacement turn signal bulbs from online sources like Amazon and RockAuto. 
Check your owner’s manual for bulb specifications to ensure you buy the correct light for your vehicle.

How will a mechanic replace my turn signal bulb?

While they require extra care, turn signal bulb replacements are typically fast and easy jobs for mechanics. If your car has a malfunctioning turn signal bulb, your mechanic will replace it by following these steps:
  1. Preparation: Your mechanic will inspect and test your turn signals to verify which ones aren’t working and then turn your car off. To safely begin the process, they will disconnect your car battery.
  2. Access the turn signal housing: Depending on your car’s design and whether your front turn signals or your back turn signals are malfunctioning, the mechanic will access the turn signal housing from either under the vehicle’s hood, the rear exterior, or through the trunk. They may need to remove trim panels and your back or front light lenses to change the turn signal bulb.
  3. Remove the old bulb: Your mechanic will gently remove the turn signal bulb by twisting it counterclockwise.
  4. Inspect the socket: To ensure the new bulb will function correctly, your mechanic will analyze the turn signal bulb socket. If there are any signs of corrosion or wear, your mechanic will clean or repair the socket.
  5. Install the new bulb: Your mechanic will install the new turn signal bulb by twisting it clockwise in the correct bulb socket. 
  6. Reassemble the housing: If any trim panels or vehicle parts were removed to access the turn signal or light assembly, your mechanic will reinstall them.
  7. Test: With your vehicle turned on, your mechanic will activate your turn signals to ensure they are blinking.

What happens if I don’t replace my turn signal bulb?

If your turn signal bulb is not blinking correctly, don’t wait to get an inspection. A malfunctioning turn signal bulb can lead to the following issues:
  • Impaired communication between you and other drivers or pedestrians when you change lanes or turn
  • Car accidents during lane changes or turns
  • Traffic violations since functioning turn signals are required by law

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:
  1. 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.
  2. 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.
  3. Dim turn signal lighting: If your turn signals are dimly lit when activated, your bulb may be in need of a replacement. 
  4. 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.


It typically costs $0 for a certified mechanic to replace a turn signal bulb. This price includes $0 for parts and $0 for labor costs. With this said, the price may be higher depending on your specific vehicle and the number of turn signals that require replacements.
