Linear garage door openers like other brands of garage door openers on the market have a plastic lens cover that protects the light bulbs on the garage door operator. If the lens cover on your Linear 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 217645 Light Cover is compatible with the Linear LDO33 and LDO50 garage door operator models.
