Bright Interior Lighting Where You Need It: Durable Incandescent Dome Light

When you need dependable light inside your trailer, this rectangular dome light does the job simply and well. Measuring 4-9/16" long by 2-1/2" tall, it uses one 1156 incandescent bulb to deliver bright white light that spreads evenly across your workspace or cargo area. It’s built for 12V DC systems and draws 2.4 amps at 12.8V, giving you plenty of usable light wherever it’s installed.

Simple Control at Your Fingertips: Built-In Push-Button Switch

No need to hunt for a separate switch or wire in extra parts—this light includes its own built-in push-button on/off control. Power when you want it, off when you don’t, all right there on the fixture. The two-wire design keeps wiring easy with one power lead and one ground wire.

Reliable in Wet and Rough Conditions: Sealed, Waterproof Housing

If moisture is part of your environment, this light is ready. The sealed housing and lens are fully waterproof and submersible, keeping the bulb and internal components protected from water damage or corrosion. Whether it’s humidity inside an enclosed space or full submersion on a boat trailer, the circuit stays dry and functional.

Built to Last: Steel Base and Clear Polycarbonate Lens

The steel base gives this light solid backing while the clear polycarbonate lens keeps it lightweight and impact-resistant. Together they make a sturdy light that handles vibration and daily use without cracking or loosening up. It surface mounts cleanly with hardware (not included) spaced 3-1/2" center on center, so installation is quick and straightforward.

Straightforward Upkeep: Replaceable Bulb and Common Fit

When the time comes to change the bulb, it’s a standard 1156 type—easy to find and replace without special tools or parts. It even cross-references directly with Uni Bond # DL2050S, Peterson # M391, and Bargman # 40-15-005, making it a direct replacement for several common fixtures already out there.
