4.1 Replacing the LED Optical Assembly Components
To replace a broken or cracked glassware or LED mounting assembly, unlatch the lock ring and remove the glassware
assembly from the top of the obstruction light housing. See

Disconnect the LED light assembly connections to the power supply.
Remove the four flat head screws that hold the LED assembly place and then lift off the glassware. Remove the rubber seals
and discard the broken or cracked glassware.
Note
When replacing the glassware or LED mounting assembly, ADB recommends replacing the lens seal to insure
optimum sealing.
Note
The individual LEDs are not replaceable. The entire LED mounting assembly must be replaced.
Reassemble the components in reverse order. Apply Loctite 242 to the threads. Torque the four flat head screws to 22-25 in-
