Yup. The # M357FR is a recessed/flush footprint so you'll just trace the cutout size of 11-5/8" wide x 8-3/4" tall, pilot your corners, and deburr the opening. Use a gasket/sealant bead, and you’ll get that sleek “factory” look! One thing to note is that most aluminum trailers aren't going to give the best ground to the frame, so you'll get better results when running the ground wire straight to the 12v source (usually the battery).

Do you already have a light installed, or is this a new add-on?
