Drivers tape headlights for a few different reasons. Race car drivers cover their headlights with tape to protect them against being chipped or cracked during the race. Sometimes it is necessary to tape over a broken headlight to protect it against moisture rain. You might also want to tape around the edges of a headlight if you are painting close to the headlight or restoring it. In most cases painter's tape or masking take work well without leaving much tape residue.
Cover the headlight with clear packing tape. Secure the tape around the edges of the headlight, pushing into the gap between the body of the car and the light.
Tape around the edges of the packing tape with masking tape or painter's tape. This helps form a more secure bond to prevent moisture from working its way into the headlight.
Gently press and smooth the tape with your hand so that it fits tightly to the headlight. Inspect the taping job to make sure it is secure, with no gaps.
Determine what type of tape or material to use. Many drivers use painter's tape. Painter's tape typically comes in a blue colour but it available in other colours as well. Some drivers prefer to use 3m protective film to cover the headlights because it is transparent.
Unplug the headlight. This prevents it from melting the tape or protective film covering.
Cover the headlight with painter's tape or 3m protective film. Secure tape or protective film to the edges of the headlight. Tuck the edge of the tape or film securely into the gap between the headlight and the body of the car.
Gently press the tape or protective film with your hand to make sure that it fits securely to the headlight.
