Can M3 12v 24v LED RV Exterior Light M378FR Be Dimmed?

Published 09/11/2025

Question:

Is the black light just an on/off, or can it be dimmed?

Nicole, the # M378FR is strictly on/off. It isn’t designed for use with dimmer switches, so if you want mood lighting, you’d need to add a separate lower-output fixture (most lights like this cannot be dimmed, or at least are not advertised as being able to). Most folks pair a big LED like this with a smaller porch light so they can pick between “soft glow” or “full blast.” And even those are not normally dimmable.

Do you want it for ambiance or more for security?
