The grommet cushions the lamp against vibration and road shock, which helps prevent bulb filament breakage and extends the life of both incandescent and LED lights. It also eliminates outgassing that can fog the lens, and replaces cracked, dried, or missing grommets to maintain a weather-tight, rattle-free installation.
