These base flange mounted, commercial lights feature one-handed bulb changing; simply loosen the thumbscrew and twist the top off. The double navigation lights provide a spare lamp unit for immediate switching in case of bulb failure, and also allow for one-handed bulb changing. The top quickly removes from the main (upper) unit, and the entire upper unit hinges to allow access to the spare (lower) unit.
