⚠️ Safety & Precautions

• Turn the lights off and remove the key fob from the vehicle before starting.
• Let the rear lamps cool down if they were just on; bulbs and housings can get hot.
• Use a trim tool carefully so you do not crack the lamp lens or scratch the paint.
• If the bulb does not use a replaceable socket and the lamp is LED, the whole lamp assembly must be serviced instead.
