Video Transcript for Optronics Trailer Lights - Reflectors - RE37RB Review

Today we're going to be taking a look at the Optronics round red reflector. We're going to take a quick look at the diameter of the reflector. Measuring edge to edge it's going to give us a diameter measurement of 2 3/16th of an inch. It's going to feature a nice acrylic lens. It's a surface mount installation. It's got the adhesive backing so all you've go to do is peel that off and then stick it to a nice clean surface.

This is SAE and Department of Transportation compliant. When it comes to the thickness it's only going to measure about 3/16ths of an inch to a quarter of an inch thick. That's going to do it for today's look at the Optronics round red reflector.

Perfect fit and arrived four days early. Thank you.


Even though they did"nt have the other reflectors, they still sent my order
in a quick time after my order change with them.



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!

All is still working great!

Your product was exactly as described. I was pleased with quality and will work fine for its intended use. Price was reasonable also. Very satisfied. Gary


Good enough quality. You get what you pay for.


The red reflectors worked good for the rear side marker lights my trailer was missing.


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.


received timely and in good condition. Installed into the tail reflector receptacle on my 1972 Schwinn Collegiate easily, using the self adhesive backing.
