in my boat i mount a couple pieces of 1/2 inch conduit a couple ft long on the brace going around the windshield on the center console and use the clamp on lights with the small metal reflectors with a 12 volt 40 watt rv lightbulb. the lights can be bought about anywhere. i use the small reflectors to help with storage. put a couple clips on the wire and hook it to the batts.the lights are about 7 ft high and can be adjusted to shine anywhere in the boat. i shine em down into the boat, one light pointed to the front and one to the rear.
listen with your eyes---its the only way to beleive what you hear...
