The 12V version of this low-profile recessed courtesy light is supplied with a double o-ring seal and a form-fit trim ring/lens assembly which stays secure even in the worst conditions. The double-molded hermetically sealed LED assembly keeps moisture out from behind resulting in a maintenance-free fixture. The single 10mm LED draws a miniscule 3.2mA (at 12V). Installation is made easy due to round cut-out.
