Turn Signal Bulb Replacement: A Step-By-Step Guide
Cars have turn signal bulbs at the front (passenger and driver side) and back of the vehicle. Depending on the location of the faulty bulb, you’ll have to remove the trim pieces to access it.
But doing this yourself can be tricky if you’re not used to car repairs. So, it’s best to hire a professional with broad expertise to handle these tasks.
Here’s how a mechanic will replace a turn signal light bulb:
Step 1: Prep the Vehicle for Safety
First, they’ll park the car on a flat surface and engage the parking brake to keep it from moving. Then, they’ll switch off the ignition to let the car cool so that the parts are easy to dismantle. The mechanic will also disconnect the car battery to prevent electrical mishaps.
Step 2: Access the Faulty Turn Signal Bulb
Next, they’ll locate the faulty bulb. If it’s in the front (passenger or driver side), they’ll open the hood. But if it’s in the rear, they’ll need to open your car’s trunk.
To access the faulty bulb, the mechanic will detach car body components or trim pieces using a screwdriver, pliers, or trim stick. They may also refer to your car’s manual (if needed) to check which components to remove.
Step 3: Disconnect the Electrical Connections
Now, they’ll pull back or press a clip to pull the harness (electrical connector) backward away from the bulb housing (place where the bulb is fixed).
Note: Some cars may have a bulb socket attached to the harness. In such situations, the mechanic will turn it counterclockwise to detach it.
Step 4: Remove the Old Bulb
The mechanic will grip the base of the bulb housing plate and turn it counterclockwise. They’ll do this until the bulb is released. In some cars, they may have to apply force to loosen the bulbs. They’ll also check the bulb socket for corrosion. If it’s corroded, they’ll clean it with sandpaper.
Step 5: Install the New Bulb
Using a cloth piece, they’ll hold the new bulb and fix it into the bulb housing plate. Then, they’ll turn the bulb clockwise to secure it in place.
Step 6: Reconnect the Wiring and the Battery
Now, the mechanic will reconnect the wiring (electrical connector) by pressing it onto the clip until they hear a clicking sound. Then, they’ll reconnect the battery.
Step 7: Test the Turn Signals and Reattach the Car Components
Before refixing the trim pieces, they’ll test the turn signal lights. They’ll push the turn signal lever to turn on the flasher. During the check, they’ll also inspect the brake light, headlight, fog lights, and hazard lights for any issues.
The mechanic will reinstall the trim pieces and finish the replacement.
Now that we know how a turn signal bulb is replaced, let’s find out its cost.
How Much Does a Turn Signal Bulb Replacement Cost?
The average cost of a turn signal bulb replacement can range from $85 to $685 (both parts and labor).
These replacement estimates depend on the type of bulb (a premium bulb could cost more), the car model, and the repair shop you visit.

5 FAQs on Turn Signal Light Bulbs
Here’s some information about flasher bulbs that you should know:
1. Can I Drive with a Failing Turn Signal Bulb?
No, you shouldn’t drive a car with a failing turn signal bulb. It’s a safety hazard, as it fails to inform other drivers when you take a turn.
Moreover, it’s mandatory to use turn signals, otherwise you may face a penalty. In case the blinker is non-functional, you (the driver) have to compensate by using hand signals.
To avoid such fines and inconvenience, you should replace the faulty bulb ASAP.
2. What Are the Symptoms of a Failing Turn Signal Bulb?
Some signs you’ll notice when your car’s turn signals fail are:
- The turn signal indicator on your car’s dashboard flashes irregularly
- Unresponsive hazard lights due to faulty wiring
- A worn-out or dim turn signal bulb due to regular wear and tear
- A non-functioning turn signal switch that causes the bulb to stop blinking
3. How Long Does a Turn Signal Light Bulb Last?
Turn signal bulbs can last approximately between 3,000 and 5,000 hours. However, premature wear could cause the turn signal lights to malfunction sooner.
Note: A premium bulb can last longer than standard bulbs, depending on factors such as their construction, lamp coating, and design.
It’s advisable to replace an old bulb if it shows any signs of failure.
4. What Are the Different Types of Turn Signal Bulbs?
The common flasher bulb options you find in the market are:
- Light-Emitting Diode (LED bulb): These bulbs are expensive, but LED turn signal bulbs are energy-efficient and highly durable. These types are also known for producing a bright headlight.
- Halogen bulbs: These bulbs use a proprietary gas mixture to produce light. They’re more affordable than an LED bulb but are less energy-efficient.
- Incandescent bulbs: These bulbs are ideal if you want an economical alternative with simple installation. However, they don’t last very long.
Looking for some recommendations?
Sylvania LEDs offers options like Sylvania Amber ZEVO premium bulb and Sylvania Amber SYL standard LED bulb. Other top brands for LED turn signal bulbs include Auxbeam, JDM ASTAR, and Alla Lighting.
5. How Do I Take Care of My Car’s Turn Signal Bulbs?
Maintain your car’s blinker by following these simple steps:
- Regularly check for any signs of a malfunctioning turn signal light bulb.
- Ask a mechanic to perform basic repair procedures to help prolong the effectiveness of the bulbs.
- Avoid touching the bulbs directly with your hand to prevent any natural oil from your skin from transferring onto the bulb. The natural oils can stick to the bulb, causing uneven heating, reducing lifespan, and possibly damaging its lamp coating.
