🔧 Taillight Bulbs - Replacement

Assumption: This applies if your F-150 has bulb-service taillamps. If the rear lamp is LED-sealed, the bulbs are not replaceable and the whole lamp assembly must be replaced.

Replacing both rear taillight bulbs is a quick job once the lamp housing is removed. On this truck, the outside bulbs are typically serviced from inside the bed area by removing the taillight assembly and swapping the bulbs from the back.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour

⚠️ Safety & Precautions

• Turn the lights off before starting.
• Let the bulbs cool before touching them.
• Do not touch glass bulbs with bare fingers; oil can shorten bulb life.
• Support the taillight as you remove the last fastener so it does not drop.
• If your truck has LED taillamps, the bulbs are not serviceable.
