Another great option to bring Ice Hole Powers glow cup to your hard water needs! Includes mount, glow cup, switch and female spade connectors. Added mounting option for other brands. If your installing on other brands then Vexilar choose Universal L Mount. Marcum Lithum Shuttle owners choose no mount, you should be able to just bolt directly to the 1/4" mounting points on the shuttle.
 
Recommended that cups are wired with a 5 amp fuse in the circuit.
