INSTALLATION STEP 8

Install the Lights

• Press the release tabs on both sides of lens. Gently rotate lens

back and downward until the lens hinge is in the fully open

position. Do not remove the lens.

• Install a 100 watt maximum light bulb in each socket. Light

bulb size should be A19, standard neck only. The lights will

turn ON and remain lit for approximately 4-1/2 minutes when

power is connected. Then the lights will turn OFF.

• To remove, depress both top lens tabs. Tilt lens slightly

outward and down, then pull out to clear bulbs. Use care to

avoid snapping off bottom lens tabs.

• Use A19, standard neck garage door opener bulbs for

replacement.

NOTE: Use only standard light bulbs. The use of short neck or

speciality light bulbs may overheat the endpanel or light socket.
