Tranmpk,
Remote controlled spotlights/motors often fail after three years of exposure due to salt spray and/or tiny complex cable wire motors/light controller runs. Warranties reflect that.
Vessels underway at night should only display their red, green and white ‘steaming’ lights and no others. See Chapman’s or take any approved Boating Safety Course for details.
Any type of boat underway ‘headlights’ degrade the night vision of other boaters as well as the skipper from bow rail reflections; that’s why they are forbidden. Vessels underway at night depend on their NIGHT VISION, not on their headlights.
If you are disoriented, or not EXACTLY sure where you are, you should immediately STOP. Then you can use your ‘spotlight’ to confirm nearby ATONS without blinding other vessels nearby.
After 40 years of trying everything, we avoid boating after dark. When you must, to pick out a ATON, we finally found that NOTHING beats a Marinebeam Long Range Illuminator. Shine it out a window and you won’t hit the bow rails. Works at 500 YARDS (NOT A TYPO, YARDS NOT FEET).

You won’t believe it til you buy it. ⅓ the price of your ‘spotlight’ but runs three days continuous on three D batteries with no heat, weatherproof, and lifetime warranty.
Hope this is helpful.
