• Recommended Rectangle Exterior LED Lights for 24v Electrical Systems
  No, it can not Ed but I have a couple similar ones that can be used with a 24v system. They are the Exterior LED Utility Light item # M378FR in black or item # M388FR in gray.

• Can RV Exterior LED Utility Lights Be Used With 12V AND 24V Systems While Off-Grid?
  Greg, you’re all set. Both the gray # M388FR and black # M378FR are designed to run on 12V or 24V DC without any extra converters. That makes them a flexible choice for RVs, trailers, or even truck-based rigs that run 24V instead. Are you running other accessories on that trailer? Luckily these don't draw much amperage at all, so you'll be fine off-grid as long as other accessories/appliances don't pull your battery bank down too much. If they do, you can always use a portable solar...

• LED Exterior Work Light For Toy Hauler Above Ramp Door That Holds Up In Rain And Snow
  Marissa, either version the # M388FR in gray or the # M378FR in black will hold up fine. The housing is powder-coated aluminum, and the LED board is sealed for outdoor use (includes foam seal with adhesive for a good seal). They are built for rain and spray on the road, and the snow and other elements, so no worries there. If you want extra insurance, run a bead of silicone around the base after screwing them down - not completely necessary, but just a little added peace of mind if you...

• Is The M3 RV Exterior LED Light A Soft Warm Glow Or A Really Bright White Light?
  Eric, the # M388FR is definitely on the bright white side. LEDs put out a crisp, clear beam - great for security and task lighting, but not usually a warm amber glow. If you want softer light, some folks run a separate smaller porch light for “ambience” mode. If you want one like that, let me know and I'll find one since this # M388FR is more of bright light that illuminates a fairly large area of your entry way. Are you mostly using it while camping at night, or more for setup/tear-down...

• Can I Wire 2 LED RV Exterior Utility Lights To The Same 12v DC Switch?
  Bill, you can wire two fixtures together no problem. Just tie both positives to your switched hot lead and both negatives to ground or negative lead. Since these LEDs draw so little, you won’t overload a typical RV light circuit with a pair of gray lights # M388FR or black lights # M378FR. Are you planning to use them for general patio light or more as work-zone flood lighting? Other folks reading this - if you’ve doubled these up, how much area did they cover for you?

• Replacement LED Exterior Light That Looks OEM On 2014 Rockwood Mini Lite Camper
  Jeff, the # M388FR has a light gray finish that blends really well with modern fiberglass siding and lighter trims. It doesn’t disappear like black does on dark surfaces, but it gives a clean, OEM look without drawing attention. If you’re picky about color, a quick touch of RV touch-up paint around the edges can make it seamless, or grab a can of spray paint if you're savvy with that. I checked out pics online and I don't see a lot of gray trim on that 2014 Rockwood Mini Lite - feel free...

• Can The Exterior LED Utility Light For RVs And Enclosed Trailers Be Mounted Vertically?
  Yes, Ron - orientation doesn’t affect the LED board inside. The # M388FR will shine just fine whether horizontal or vertical. Mounted next to a door, it’ll give you a nice spread of light downward for steps. Keep in mind, the light is not adjustable like some other models, so the orientation you mount it will be fixed in that specific orientation! Do you want more patio coverage or more step-focused lighting? I'd recommend mounting it as intended, facing down instead of to the side, if...

• Bright LED Light For Side Of Grand Design Travel Trailer To See Hookup Area
  Connie, that’s exactly the kind of task the # M388FR was built for. The wedge housing angles the LEDs downward, so you get wide, usable light across your utility area. You’ll be able to see valves, cords, and gear without holding a flashlight, in fact, this might even be overkill which isn't a bad thing! Are you planning to put it right above the hookups, or offset a bit higher? Other Grand Design owners - share where you mounted yours for best coverage.

• Do I Need To Drill Or Cut Hole In Wall To Install M3 LED RV Utility Lights?
  Good catch, Hannah. Unlike recessed lights, the # M388FR gray and # M378FR black mount right on the surface (flush mount). The only “hole” you’ll need is a small one for the two-wire lead. That’s why you won’t see cutout specs listed. If you’re replacing an existing wired light, you’ll already have that access hole. Are you swapping an old fixture or adding new light where there wasn’t one before? Other folks - how tricky was your wiring through the hole when you installed?

• Replacing Yellow Lens Exterior Light On 2019 Keystone Cougar With Bright LED Utility Light
  Travis, both the gray # M388FR and the black # M378FR give you the same LED performance - it’s really just about matching the look to your trailer. This will likely be much brighter than the one you had. The powder-coated aluminum housing is weather-resistant either way. Gray tends to blend better with light siding, while black can make the fixture almost disappear on darker walls. What color is your Cougar’s trim? You could also custom paint it with some high quality paint from a local...

• Does M3 Exterior LED Utility Light For RVs And Enclosed Trailers Come With Hardware And Screws?
  Angela, you’ll want to bring your own hardware. The # M388FR includes adhesive strips to help hold it in place while you align it, which also doubles as a weather seal when mounted, but you’ll supply your own screws. Stainless steel 8 or 10 pan-heads work great, or some good quality self tapping screws depending on your application. A dab of sealant in each screw hole keeps moisture out. Do you still have the screws from your old fixture, or are you starting fresh? Sometimes you can reuse...
