Video Transcript for Optronics Round Self-Adhesive Acrylic Reflector Review

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.

I used to rebuild this trailer, brake assemblies, bearings, seals, lights and reflectors. Everything was as advertised and delivered as promised. I have started on my boat trailer now and am using etrailer again for the parts I need.
Great company, great service!

I haven't installed them yet. They are not totally flat, but hope when installed they will lay flat.

OMG, etrailer is the best! Product was shipped fast, customer service got back to me on the weekend over an issue. They didn't rip me off for shipping/handling. I highly recommend them.
