The Linear garage door openers have a plastic lens cover that protects the light bulbs on the garage door operator. If the lens cover on your Linear LDCO model garage door opener is missing or damaged it can easily be replaced. The new light cover snaps into place and can swing open to gain access to the light bulb if it needs replaced. While replacing the light cover you may want to think about replacing the bulb with an LED bulb.
The Linear 228152 Light Cover Lens is compatible with the Linear garage door operator models LDCO800 and LDCO850.
