HOW TO REPLACE A BEACON/FLASHING BULB

• CAUTION: If you have a flashing beacon or a strobe beacon, you must let the electrical system discharge for a full 24 hours before attempting to replace the bulb. This system contains high voltage and is very dangerous.

STEP 1

When you have finished viewing this presentation, use the “CAPS” program found on the home page of www.apex-inc.biz. Select the proper beacon/flashing bulb for your aircraft.

STEP 2

• There are several different types of beacon assemblies: Rotating Beacons, Flashing Beacons, Flashing Strobes.

•All have the same replacement steps.

STEP 3

• Using a stable ladder, remove the screw holding the band clamp to the lens. This is usually one screw.

• Carefully remove the clamp. The lens will be loose, don’t drop it!

STEP 4

• Remove the lens from the base plate.

STEP 5

• If the beacon assembly is a flashing/strobe type, the bulb will have a plug attached to the bottom of the bulb or the bulb will have pins.

• Disconnect the plug and install the new bulb assembly. CAUTION: DO NOT TOUCH lamp glass with fingers. Use protective cover to insert lamp. If lamp has been touched, clean carefully with cotton and alcohol.

STEP 6

• If the beacon is a rotating or single bulb system, remove the bulb by pushing down and turning 1/4 turn counter clockwise and lift the bulb out of the socket.

• Install the new bulb by pushing down and turning 1/4 turn clockwise. CAUTION: DO NOT TOUCH lamp glass with fingers. Use protective cover to insert lamp. If lamp has been touched, clean carefully with cotton and alcohol.
