Features to know about

Reliable Replacement for Broken Clearance Lights: Durable 4" x 2" Design

When an old light cracks or fails, this rectangular 4" long x 2" tall incandescent light makes for a dependable swap. It works as either a clearance or side marker light, with a black ABS plastic base and an amber acrylic lens that includes a built-in reflex reflector. The lens is replaceable, so if it ever gets damaged you can change it out without replacing the whole fixture.

Simple Mounting for Quick Fixes: Surface-Mount with 3" Centers

You don’t need special tools or custom brackets here. The light surface mounts on 3" centers using 1/4" diameter holes and connects with a twist-in bulb socket that includes both a power lead and ground wire. Just drill a small hole for the wiring and bulb base, mount it up, and it’s ready to work. Hardware isn’t included, giving you flexibility to use whatever fasteners match your setup best.

Good Light Output Without Excess Power Draw: P2-Rated Incandescent Bulb

This light uses a standard 194 bulb that draws only 0.2 amps at 12.8V, giving solid illumination without adding much electrical load. The P2 rating means it shines in a 90-degree pattern (45 degrees to each side of center), making it perfect for use as either a clearance or side marker light when properly positioned.

Built for Everyday Use: DOT-Compliant and Backed by a 3-Year Warranty

The MC32ABB meets DOT requirements so you can stay compliant on the road. Its non-submersible design is ideal for dry-use trailers or any installation where water exposure isn’t a concern. Backed by a 3-year warranty, it’s a straightforward solution that installs easily and holds up well under regular use.

It's very hard to find a black base on marker lights in local stores throughout the US. I'm glad etrailer carries black base marker lights to match my camper's other lights. This worked great!

Exactly what needed
by:
2013 Winnebago Vista
Good replacement for the Glo-Brite position lamps on my 2013 Winnebago Vista. Glo-Brite is no longer in business and these are recommended by Winnebago as a replacement. Unfortunately, some drilling is required b/c the wires exit the fixture in a different spot than the original lamps, and the rubber seal around the new lamp socket (where the wires exit) protrudes from the back of the fixture, so a new hole in the center is required to make this part fit. However, the mounting screws are in the same location, so no new holes are required for those.
by:
I needed to replace a clearance light on my travel trailer and this light was the exact replacement by the Manufacturer and was identical to to original. Fully satisfied with this product. 2022 Springdale trailer.
by:
Very happy with my purchase. These lights are the exact same as the OEM lights on my '15 Forest River Grey Wolf. My reason for purchase was that one original of the lenses had gone missing (likely on the side of the highway somewhere) and a full replacement light was less expensive than a replacement lens alone. At etrailer's low price I decided to buy a couple more to have on hand. etrailer ships very fast with no hassles at all. They are my go-to for all trailer needs as their prices are very competitive and their customer service is excellent.
by:
I only really needed to get the lens cover for the lights, but with the price being very affordable I bought the whole unit, 2 red and 2 amber for front and rear clearance lights. When I received them, I removed the lens cover and it fit perfectly over my existing clearance lights. I will just save the light and wiring if I need them in the future. Customer rep Ashley was great helping me over the phone. This is my second purchase from etrailer and will come back to them for future needs
by:
Great price for item with reasonable shipping costs. Was a exact match to item being replaced and was delivered in a timely manner.
by:
Perfect replacement for one with a black base. Simple to install.
by:
Received in a timely manner as always. I only used the lense to replace one that fell off of my 2017 fifth wheel these fit much tighter than the Optronic lenses that came stock on my trailer. Once again a satisfied customer.
Thank you etrailer
by:
Worked well was very similar to the unique side light that was existing on the trailer.
by:
Return customer : ) Exact replacement marker light on Fleetwood Niagara. Great price and super quick shipping. Couldn’t be happier.
by:
I used this as a replacement for a clearance light on my RV. It was an exact duplicate and worked great.
by:
This is exactly what I needed. As always, etrailer comes through with all of my trailer parts.
by:
Bought these to replace cracked lenses on our travel trailer, they're a perfect fit and well priced. A year after we bought and installed them, they're not showing any signs of deterioration.
by:
Matched the OEM lights on my trailer perfectly. Shipping was lightning fast and communication was excellent.
