Don't buy a cheap one. I got one from BW and it only lasted a season. Managed a repair once, had to replace steel bolts in the thing that rusted, then the thing broke beyond repair. A suggestion on the mount. Don't mount it on the front of the hard top. If you mount it toward the rear you won't get as much glare from the light hitting the bow and railings. Sometimes the glare is worse than the dark.
