I bought a pair of these to replace a set of trailer side markers. Simple to install and came with a set of sheet metel screws. Just orientate the base housing keeping the weep hole at the bottom. Plenty of lead lenghth to work with, too. Overall, these markers provide very good illumination. 555837
