FWIW I use a GoLight wired version with wired remote ... and just run the wires back to the cig/assy socket on the main helm. They also make a wireless version, but you'd need to add a power supply waterproof connection near where mounted.
I made a simple starboard mount that affiex to the forward end of the pulpit with SS clamps that is secured with a bungee. NO GLARE from anywhere on the boat! Light was $100, clamps $8 and I used some scrap material or one could use a cheap cutting board from WallyWorld.
Simple to setup and use, cheap (or GREAT value) and the light will last forever as it isn't constantly exposed to the salt environment and UV.
