Today we'll be reviewing part number BU41CB. This is the 4 1/2 inch round, clear trailer backup light from Optronics. The round trailer light is going to function as a backup light. It's going to feature your clear acrylic lens with a strong, durable steel housing that's going to hold up well against the elements. It's going to feature a replaceable snap-on lens as well as a easy to replace bulb. This is a incandescent bulb system.
It is designed to be a flange mount with the three mount holes that are spaced equally on the flange. You can see those right there. It's going to feature a two-wire design, including the lead wire, and then the white wire is going to be your ground wire. If we take a overall measure of the diameter of the unit, including the housing it's going to give us a measurement of 5 3/8 of an inch. It's going to give us a depth of 1 9/16 of an inch. Those holes, center on center, are going to be separated by 4 1/4 inch, and again that's going to be equal spacing as far as center on center, the distance between the holes.
We're going to go ahead and hook this up to our external power source that way you can see what it looks like with power running to it, and with our overhead lights turned off. So we need to go ahead and connect the ground wire, and then we're going to connect our reverse function. So you can see here it's going to send out a nice consistent signal. Pretty quick response time for an incandescent light. And that clear acrylic lens allows a lot of light to come through, again sending out a nice clear, consistent reverse light signal. That's going to do it for today's review of part number BU41CB.
This is the 4 1/2 inch round, clear trailer backup light from Optronics. .

5-3/8" Round. Incandescent trailer light functions as a back-up light. Replaceable lens and bulb. Corrosion resistant steel housing. Recessed mount with built-in flange. 2-Wire design. (1) 1076 incandescent bulb included.I often recommend Etrailer to people in my community of RV repair and Renewable Energy. I wish someone would do a video on how to replace hubs-wheels-bearings on older travel trailers with the Dayton-Dexter-Fayette Star wheels and include details on how to identify the axle and weight class. If you want to see what your products have been used on, heres an Example. I bet you never thought Etrailer would be the source for parts on a wind turbines pivot, shaft and furling parts!

Bought these to match the tail lights i already had, i like the style and quality of the lights so far. I have yet to wire them up but they are mounted and look good. From my experience i would buy again.
Seem like a great product, simple and strait forward installation. 4 stars is only because I don't yet how well they will withstand the test of time.
I had great experience with your Company. I placed an order it came in, package was short one gasket, I emailed your Company, Trever reacted immediately, and had the missing gasket sent out. I couldn't ask for anything better.
Good product, great price. Extra quick shipping. These are mounted in the tailgate of my Explorer with high power LEDs in them (one red one amber). I am a Fire Chaplain and respond to emergencies all over the county. These are part of my emergency light set up and do a great job. I did paint the fixtures with Gloss white automotive enamel and they blend right in to the tailgate. Etrailer has always given me good service with a good product at a good price. Hard to beat that combination.
Gents [and ladies] - I chose to purchase these lights from you due to your low cost. The quality of the fixture is perfect. Its single cast piece design makes it mostly water proof. Being flush mount keeps it from mechanical harm. I intend to use it camping and Ice fishing but I will replace the incandescent with an Led and a PWM ckt.
Thanx - Jeff.
The order was correct shipped quickly and was accurate. These are the original replacement appearing 4" back up lights for trailers. These fit my 39 foot fifth wheel perfectly!
Perfect fit to replace my existing sealed unit back up lights
The backup lights were just what I was looking for. This was the only place I could find them. They arrived in just a few days and were in perfect condition.

etrailer was the only place that I could find this particular light with a clear lens. Very solid housing. Well made. Even comes with a rubber gasket. Thanks.
Excellent fixture. Solid metal housing. I bought this light because of the replaceable lens and bulbs.
Product delivered quickly and exactly as described. I am installing them in a 6 wheel ATV project and they fit well. The price was right too! Will add pictures as soon as I finish the paint job.
