⚠️ Safety & Precautions

• Turn the headlight switch off and remove the key/fob before starting.
• Headlight bulbs get very hot. Let them cool before touching them.
• Do not touch the glass on halogen bulbs with bare fingers. Oil from skin can shorten bulb life.
• If your Jetta has HID or LED headlamps, do not attempt bulb replacement this way. This procedure assumes halogen bulbs.
