Features to know about

Brighter, Longer-Lasting, and Efficient: Amber LED Marker Light

If you’re tired of swapping bulbs or dealing with weak glow from old incandescent lights, this small amber LED light is a solid step up. With a single diode that draws just 0.023 amps at 12.8V, it gives off bright, clean illumination while using very little power. The LED lasts up to 50 times longer than a traditional bulb, so you get reliable lighting without worrying about burned-out filaments or replacements down the road.

Dealing with Water Exposure: Fully Submersible and Sealed Construction

Water and electrical parts don’t mix—unless the light is built like this one. Its polycarbonate lens and housing are sonically sealed together to form a single waterproof unit that’s fully submersible. That means no water sneaking in to corrode the circuit board or kill your light. Whether it’s rain, road spray, or a dunk at the boat ramp, this light stays protected and working.

Tight Mounting Spaces: Compact and Versatile Install Options

At just 2-1/2" long, 1-1/4" wide, and 1" thick, this mini thinline light fits easily wherever you need visibility. You can surface-mount it with an open-back or self-grounding bracket (sold separately), or flush-mount it with a grommet if you want a smooth finish. It accepts standard 1-prong or 2-prong plugs, making installation straightforward and compatible with existing setups.

Clear Visibility Where It Counts: P2-Rated Beam Pattern

This light’s P2 rating gives you a 90-degree total beam spread—45 degrees to each side of center—so it’s visible head-on and ideal for use as either a clearance or side marker light. That focused pattern helps define your trailer’s edges clearly without wasted light spill, keeping you visible and compliant out on the road.
