Generally, for lift and trailer boats we recommend our stainless steel SCM series lights. Their low profile and compact design make them easy to mount in a variety of compact locations, and their polished stainless finish provide a nice aesthetic. Boats that live in the water continuously typically use our SCR round series under water lights. The glass lens and smooth exterior finish make them a better option for combating marine growth.
