š Before You Begin
- Park on level ground and set the parking brake.
- Open the rear hatch for access to the tail lamp fasteners.
- Tip: Do one side at a time. This helps you compare parts.
šØ Step-by-Step Instructions
Follow these steps in order:
Assumption: Your Soul uses a twist-lock bulb socket inside the outer tail lamp. Bulb type can vary by build; match the new bulb to the old bulbās number stamped on the base.
Step 1: Access the tail lamp fasteners
- Open the hatch and locate the access area next to the tail lamp.
- Use a trim removal tool (a plastic pry tool that pops clips without damage) to gently pop off any small interior cover panels if equipped.
Step 2: Remove the tail lamp retaining nuts
- Use a 10mm socket, 6" socket extension, and 1/4" drive ratchet to remove the tail lamp nuts.
- Place the nuts in a safe spot so they donāt fall into the body cavity.
- When reinstalling, snug them evenly: Torque to 3-5 Nm (27-44 in-lbs).
Step 3: Release the tail lamp assembly from the body
- Hold the lamp with both hands and pull it straight rearward.
- If it feels stuck, use a trim removal tool to gently help it release from the alignment pins.
- Tip: Pull straight back, not sideways.
Step 4: Remove the rear turn signal bulb socket
- Identify the turn-signal socket (usually the lower/outer socket compared to the brake/tail).
- Twist the socket counterclockwise about 1/4 turn by hand, then pull it out.
- If your fingers slip, use a clean shop towel for extra grip.
Step 5: Replace the bulb
- Pull the old bulb straight out of the socket.
- Wear nitrile gloves and install the new bulb (match the base and the stamped number).
- If desired, apply a tiny amount of dielectric grease to the socket seal area (not on the bulb glass).
Step 6: Reinstall the socket and test
- Insert the socket into the lamp and twist clockwise until it locks.
- Before reinstalling the lamp fully, turn the ignition to ON and activate the turn signal to verify it flashes correctly.
- If it doesnāt work, remove the socket and re-seat the bulb firmly.
Step 7: Reinstall the tail lamp assembly
- Align the tail lamp locating pins with the body holes and push the lamp straight in by hand.
- Install the nuts using the 10mm socket, 6" socket extension, and 1/4" drive ratchet, then Torque to 3-5 Nm (27-44 in-lbs).
- Reinstall any interior access covers using the trim removal tool.
ā After Repair
- Test left and right rear turn signals, hazards, and brake lights.
- Confirm the lamp sits flush and there are no gaps (helps prevent water leaks).
- If you had āfast blinkingā before, it should be normal now.
