Features to know about

Better Visibility in Low Light: 2-3/16" Red Reflector

When you need to boost visibility after dark or in low-light conditions, this 2-3/16" round red reflector does the job simply and effectively. Its bright red acrylic lens catches headlights and other light sources, making your trailer or project stand out from a distance. It’s an easy way to add a layer of safety without running wires or tapping into your electrical system.

Optronics 2-3/16 inch round red acrylic reflector with self-adhesive backing for surface mount on trailers or vehicles

Simple Mounting Without Tools: Self-Adhesive Surface Mount

No need for screws or drilling. This reflector uses a self-adhesive back that sticks securely to flat surfaces, saving you time and keeping your setup clean. Just peel and press—the strong adhesive holds tight, even through vibration and road use. Whether you’re adding reflectors to a trailer frame, tool box, or custom project, installation couldn’t be easier.

Durable Construction That Lasts: Acrylic Lens Build

Built with an acrylic lens, this reflector is made to handle the elements. The sturdy material resists cracking and fading, so it stays clear and bright over time. That means less maintenance and longer service life, even when exposed to sun, rain, or debris on the road.

Compact and Versatile Fit: Round Design for Multiple Uses

At 2-3/16" in diameter, this round, surface-mount reflector fits where you need extra visibility without taking up much space. The clean circular shape works well on flat panels or curved corners alike, giving you flexibility for a variety of lighting or safety applications.

Video Transcript for An In-Depth Look at the 2-3/16" Round, Acrylic Reflector, Self-Adhesive

Hey, everybody. Ryan here at etrailer. Today we're gonna be checking out the Optronics Round Stick-On Trailer Reflector. These reflectors are great to get your trailer some extra visibility, you know, especially in cases where you don't really want to have to run a light, or just unable to simply due to the location. So, these will kind of fill that gap, you know, and being that they just use sticky tape, you can pretty much put them anywhere. When you do go to mount these things up though, to help it actually adhere, I do suggest making sure the surface is clean and dry.

I like to use rubbing alcohol, give it a minute to dry. And the sticky tape actually holds up pretty well, does a good job keeping everything in place. With this being a red reflector, when you go to mount theses up, you wanna face some towards the back of the trailer. If you're gonna be doing anything on the front or the sides, you know, you generally want to use the amber, orange colored reflectors, which, you know, these are also available in that color. And just to compare it to a lot of other reflectors, you know, there's tons of different shapes and sizes and things like that.

Here's another stick-on one from Optronics, just to kind of give you an example. You know, and having all these different shapes and sizes really lets you mount these things up anywhere. So, for example, you know, if this one we're any bigger, it really wouldn't fit that great here, and this would be a good option to change it up. To make sure it'll work with your mounting location, the size of this is gonna be two and three sixteens of an inch. Other than that, at the end of the day, you know, not a whole lot to it.

This'll make for a great direct replacement, or even potentially an upgrade, if you're going through the trailer and kind of freshening it all up. But with that said, that'll finish up our look at of the Optronics Round Stick-On Reflector.
