Technician Note
When two catalog rows use the same K108D0078 manufacturer number, treat 108D60 and 108D78 as related search names for the same lens family unless your parts diagram says otherwise.
Before Ordering
- Confirm whether the old lens is marked 108D78, 108D60, or 108D0078.
- Check the opener parts diagram for K108D0078.
- Compare retaining tabs and lens curve before installation.
- Inspect for broken housing clips if the old cover fell off.

Professional Advisory
A replacement lens should not be installed over a burned socket or damaged wiring. Electrical problems inside the opener head should be handled by a qualified garage door technician.
Product Questions & Answers
Is 108D78 the current part number?
108D78 is a common lens number for this light cover. The current manufacturer listing is commonly shown as K108D0078, with 108D78 and 108D60 as related numbers.
How is this different from K108D0079M?
K108D0078 and K108D0079M are different light lens families. Even if both are LiftMaster lens covers, they should not be swapped unless the opener parts diagram confirms the same replacement part.
Can I replace only one lens if my opener has more than one light cover?
Yes, if the opener uses separate covers and only one is damaged. Match the specific lens needed for that side or model, and order the correct quantity if both covers are damaged.
Why does my old lens have a different number than the product title?
LiftMaster and Chamberlain parts often appear under molded lens numbers, older catalog numbers, and current service part numbers. Matching the service part family is more important than matching the wording exactly.
Does this lens come with installation hardware?
The lens is normally supplied as the cover only. Reuse intact factory clips or mounting points on the opener housing unless the parts listing specifically includes extra hardware.
