⚠️ Safety & Precautions

• Turn the ignition off and remove the key or fob from the vehicle.
• Let the rear lamps cool down before touching them.
• Use care when prying the lamp housing so you do not crack the lens or body clips.
• If you are working near the battery, disconnect the negative battery cable only if needed.
• Handle the new bulb with clean hands or gloves. A bulb is a small glass light. Oil from skin can shorten bulb life.
