LiftMaster 108D79M Light Lens Cover

The LiftMaster 108D79M Light Lens Cover is a factory-original replacement diffuser for select LiftMaster ceiling‑mount garage door openers. It restores a clean, finished appearance and helps evenly disperse light from the opener’s lamp compartment while shielding the bulb and internal components from dust and accidental contact. Designed as a direct-fit part, this OEM lens cover replaces worn, cracked, or yellowed covers and installs quickly by aligning the tabs and snapping it into place—no wiring or programming required.

Use only on models that specifically call for part number 108D79M (also referenced as 108D79) in the opener’s owner’s manual or parts list; compatibility can vary by model generation. For safe installation, disconnect power to the opener, allow bulbs to cool, and follow the manufacturer’s bulb type and maximum wattage guidance noted on your unit. This genuine LiftMaster replacement light lens cover supports dependable, everyday residential garage use and maintains the intended illumination and protection performance of compatible LiftMaster openers.
