When clearance space is limited, this light fits where others won’t. The Peterson Thin Line Clearance or Side Marker Trailer Light measures just 3-1/2" long x 1-1/8" tall x 1-1/16" deep, giving it a compact footprint that mounts neatly to flat surfaces without sticking out. The surface-mount design can go vertical or horizontal, and with a 2-3/4" center-to-center mounting pattern, it’s easy to match existing holes.
This light uses a single 194 incandescent bulb rated for up to 15,000 hours of use. At 12V it draws only 0.25 amps, making it efficient while still putting out steady amber light through its durable, scratch-resistant acrylic lens. The amber lens delivers consistent color and brightness for clear visibility as a clearance or side marker light.
Installation is straightforward thanks to the single-wire setup. Power runs through the wire lead, and the ground connects automatically through the mounting hardware—no need for extra wires unless installed on non-metal surfaces. Just fasten it securely and you’re ready to go, making it an ideal choice for quick replacements or upgrades.
The high-impact base and snap-on lens hold up well against vibration and road wear. Its sealed construction is non-submersible but tough enough for regular towing conditions. Fully DOT compliant and P2 rated, the beam provides a 90-degree spread—perfect for use as either a clearance or side marker light when properly mounted.
Perfect for keeping things simple, this Peterson light directly replaces Grote #45253, Truck Lite #1555A, Optronics #MC68AB, and Primatronics #PT2630A. No drilling new holes or guessing at dimensions—just swap it in and you’ve got dependable lighting that fits like the original.

Fast, efficient & most important matched existing marker light with missing lense
Incandescent fixtures are getting hard to find. Etrailer always has what I need.
Just what I was looking for.They are the exact replacements for my running boards. Very easy to install and always the right price at etrailer.
Old RV needs old parts. E-Trailer was best, if not only osurce of a perfect match.
I couldn’t find a close match for the running lights on my 26 year old Winnebago Rialta - I found Etrailer and they suggested this product and it worked out great - great service , good price and quick delivery!
Fit well and looked great to replace clearance light on Rialta motorhome.
First time ordering from etrailer. So far so good. Have not installed the product yet. Easy ordering and timely delivery.
Hard to find running light lens cover was located and delivered in a timely fashion. Very pleased with response time, communication and overall customer service experience
Direct replacement for the factory installed clearance light on my 20+ year old trailer - I was really worried about finding the correct replacement parts but etrailer.com had everything I needed. The ordering process was a breeze and my order arrived quickly.
I ordered the Peterson Thin Line clearance light because Winnebago doesn’t Lange that part any more. I was really only interested in the lens as my light works, but was missing the lens. After receiving the part today I snapped the lens on my vehicle it was a perfect fit. Now o have a backup light fixture in case any of my other clearance lights fail. I ordered the part on Wed. and it arrived on Fri. And I’m on the east coast.
Product is easy to install. Product delivery was excellent. I recommend Etrailer.
These lights are exactly what I was looking for. great product with a quick delivery!!!
Looked in all the local retail boat and trailer stores and could not find this specific marker light for my boat trailer. Finally located it on the etrailer online site within just a couple of minutes and placed my order. Received the order in just a couple of days and was pleased to see it was exactly what I needed to replace one which I had broken. I use etrailer.com for all my towing and trailer needs, boat and trailer, tent trailer and my Class C motorhome.
Perfect replacement for Roadtrek 200 rooftop marker lights.
I could not find a certain brand of marker light for my 1997 Ford F-350. I searched all over the Internet. Then I found etrailer.com in Missouri. I was surprised that they had this brand of light in stock. I ordered them on a Monday and had them installed and ready to go by Thursday!
etrailer.com had an excellent staff who deliver a quality and Professional Service. 5 Stars
