The LiftMaster 108D78 Light Lens is a genuine OEM replacement light cover designed for compatible LiftMaster garage door openers. It protects the opener’s lamp and internal components from dust and incidental contact while diffusing light for better visibility in the garage. Ideal for restoring function and appearance when the original lens is cracked, yellowed, or missing, this factory part maintains the correct fit and finish specified by LiftMaster service documentation under part number 108D78.
Compatibility is model-specific; use this lens only with LiftMaster residential operators that list 108D78 in their owner’s manual or parts diagram. Installation is typically a quick DIY task: disconnect power to the opener, remove the old cover by releasing its retaining tabs or screws, and seat the new lens until it locks securely, reusing existing hardware if required. For safe operation, observe the maximum lamp type and wattage printed on your opener and allow bulbs to cool before handling. This listing includes the lens cover only; the motor unit, bulbs, and other accessories are not included.
