We have a 15 horsepower Mercury (actually, Mariner) outboard for our
RIB. We sometimes use it at night, and want to mount an all-around
white light on the motor. The motor outputs 20-40 V non-rectified,
non-regulated power. We're afraid we'll simply blow out any bulbs
intended for 12-volt use. Short of buying a voltage regulator (way
too expensive), is there any solution to this problem?

Buy a light that uses a couple of flashlight batteries.


Actually, this was our first (and second, and third) solution.
Unfortunately, the standard version of that light (a) leaks and (b)
vibrates off its screw attachment. W're tired of draining the light
and our little pot of gold for this.

That 20-40 V is what you see unloaded. Hook up a light and see what it
produces with a load.
