Which type of sealant is used for car lamp covers?

[DelAlice]

For car lamp covers, snake glue, serpentine glue, or butyl sealant is used. The lamp cover and sealing strip of car headlights are bonded with specially formulated sealant. Below is a detailed introduction about car lights: 1. Headlights: The primary purpose of headlights is to illuminate the road and objects ahead to ensure driving safety. The high beam and low beam can be alternated as a signal for overtaking at night. Headlights are installed on both sides of the front of the car, with 2 or 4 units per vehicle. The bulb power is 45-60W for high beams and 25-55W for low beams. 2. Fog lights: Fog lights are installed near the headlights or slightly lower than the headlights. In conditions of low visibility such as fog, snow, heavy rain, or dust, fog lights serve to illuminate the road and signal to oncoming vehicles. The light is mostly yellow, as yellow light has a longer wavelength and good fog-penetrating performance. The bulb power is generally 35W.
