🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm the correct side

• Turn the ignition ON briefly and activate the turn signal you’re replacing (left or right), then turn ignition OFF.
• Use a flashlight to locate the matching bulb socket behind that front grille lamp.

Step 2: Access the front turn signal bulb socket

• Open the hood and stand at the front of your Wrangler.
• Reach down behind the front grille turn-signal lamp housing on the side you’re replacing.
• If your hand space is tight, use a plastic trim tool (specialty) to gently move any nearby wiring loom aside (do not pry on the lamp lens).

Step 3: Remove the bulb socket

• Put on nitrile gloves and safety glasses.
• Grab the bulb socket and rotate it about a quarter-turn counterclockwise by hand until it unlocks.
• Pull the socket straight out of the lamp housing.

Step 4: Replace the bulb

• Remove the old bulb by pulling it straight out of the socket (it’s a wedge-base bulb, meaning it just pulls out—no twisting).
• Push the new front turn signal/parking light bulb (amber 3157/3157NA type) straight into the socket until fully seated.
• If you touch the glass, wipe clean.

Step 5: Reinstall the socket

• Insert the socket back into the lamp housing, lining up the tabs.
• Twist the socket clockwise about a quarter-turn by hand until it locks snugly (do not overtighten).

Step 6: Repeat on the other side (recommended)

• Replace the bulb on the opposite front lamp using the same steps to keep brightness/color matched.

✅ After Repair

• 🔁 Turn ignition ON and test: left turn, right turn, hazards, and parking lights.
• 👀 Walk around the front and verify both sides blink at a normal speed (fast blinking usually means a bulb isn’t seated or is the wrong type).
• 🧾 If one side still doesn’t work, re-check the socket is fully twisted/locked and the bulb is fully pushed in.
