This light has a built-in, one-piece flange. The extremely low profile (just a hair less than 3/4″ deep!) make it a great option for sleepers or mudflap hangers.

These lights will fit in any standard 4″ light hole. The total outer diameter, including the flange, is 5-2/3″ across. Connects to power with one female, three-prong, offset plug – attached to the back of the light by a few inches of wire.
