🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which bulb you’re replacing (low vs high)

• Use a small flashlight and look behind the headlamp: you’ll see two round bulb bases.
• Low beam is the main headlight used at night; high beam is the brighter “brights” function.
• Tip: Replace left and right as a pair.

Step 2: Remove the electrical connector

• Put on nitrile gloves and safety glasses.
• Press the lock tab on the connector and pull it straight off the bulb base (do not yank the wires).

Step 3: Remove the old bulb

• Grip the bulb base and twist it counterclockwise about a quarter turn, then pull it straight out.
• Use a small flashlight to make sure no rubber seal or O-ring stayed stuck in the headlamp.

Step 4: Install the new bulb (no-touch rule)

• With nitrile gloves on, hold the new bulb by the plastic base only.
• Line up the bulb tabs with the headlamp housing slots, insert fully, then twist clockwise until it locks.
• If you accidentally touch the glass, wipe it with rubbing alcohol and let it dry before installing.

Step 5: Reconnect and test

• Push the connector back on until it clicks.
• Turn the headlights on and confirm the side you replaced works.
• Repeat Steps 2-5 for the other headlight on the opposite side.

Step 6: Repeat for the other beam (if you’re doing both low and high)

• Follow the same process on the second bulb opening (low beam H11 and/or high beam 9005).
• Use a small flashlight to verify each bulb is fully seated and locked.

✅ After Repair

• Walk in front of the truck and confirm both beams look even in brightness and aim.
• If a bulb doesn’t light, re-check the connector is fully clicked in and the bulb is fully twisted/locked.
