Optronics BU33 Series Backup Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

Video Transcript for Optronics Trailer Lights - Tail Lights - BU33CB Review

Today we're going to review part number BU33CB. This is the Optronics sealed flash mount rectangle trailer back-up light with the clear lens. This is a clear rectangular trailer light that will function as your back-up light. It uses a sealed, waterproof housing and lens unit. It is corrosion resistant. On the inside, has a heavy-duty long-life bulb that's installed in a shockproof socket, which guarantees a long bulb life.

It does accept the industry standard, 2-prong plug. As you can see, this one has a 3-prong design but you can use a 2-prong plug on yours since this is only a back-up light. When you do mount this, it is flush mount design so it does require a mounting grommet and then a 2-wire pigtail to provide the power to the light. Those items are sold separately on our website. They are listed on this product page as a "related product". Just to show you, I wanted to show you first the grommet that is used and this we do sell separately.

It's part number A33GB. Basically, what you'll do is just go ahead and push your light in there. It pops into place. Then there's 2 different 2-prong pigtails. The first one is the straight 2-wire pigtail and that's part number A45CB. The straight one is designed to plug in.

It uses just the 2 connections, the ground and then the circuit for your reverse light. You go ahead and plug that in. The reason it's called the straight is because the wires will come out straight behind the light. Then the other option is this right angle to wire pigtail that's part number A49PB. The reason this one's a right angle is when you go to plug it in, you can see that the wires come out at a right angle from behind the light.

You can use either one, whichever will work in your application. I do want to give you a few dimensions on this. The overall length, edge to edge length is 5-5/16". The height from edge to edge is going to be right at 3-7/16" and then the depth on this is going to be right at about 2" deep. What I'm going to do is we're going to use one of these plugs. We're going to use the straight plug. I'm going to go ahead and plug it in and then we're going to hook these 2 wires up to 12-volt power just to show you how bright the back-up light is. The white wire will go to the ground and again, the red wire will go to the reverse light circuit. With those connected, I'm going to go turn off the overhead lights. I'm going to turn on the 12-volt power and apply the back-up light and you can see how bright the reverse light is. I'm going to turn the power; turn the lights back on. That should do it for the review on part number BU33CB. This is the Optronics sealed flash mount rectangle trailer back-up light with the clear lens. .

This reverse light was just what I needed. I have a Chevy 3500 can and chassis with a cm bed on it. I could find this light anywhere even on the cm website until I found it here. It was a great place and I appreciated the video that showed the size and prongs that were on the light so I could make sure I was getting the correct one. 581453

Ask the Experts about this Optronics Trailer Lights

Do you have a question about this Trailer Light?


  • Wiring a Wells Cargo Trailer with a 5-Way Flat Connector and Reverse Lights
  • You would need to add a 5-Way flat trailer connector, # HM47910. Cut off the plug from your old 4-Way trailer connector and then attach the wires to the new 5-Way. On a 5-Way, trailer side, the covered plug is ground, next to that is the running light wire. Next to that will be the left turn/brake light wire. Second to last is the right turn/brake light wire. And at the far end is the wire you will be using for reverse lights. You will need to run wire from the blue wire on the 5-Way...

  • Is this backup light trailer, part # 393C, waterproof?
  • This Rectangular Trailer Backup Light, part # 393C, is not sealed or waterproof. We do offer sealed and waterproof rectangular backup lights. You might try our Sealed, Flush Mount Tall Rectangle Trailer Back Up Light - Clear, part #BU33CB, which is close to the dimensions of the backup light you were interested in.

  • Can the RV Porch and Utility Light be Used on a Camper Shell for Side Illumination for Sled Dogs
  • The RV Porch and Utility Light, # RVPL3C, would definitely be able to handle normal highway speeds, if mounted correctly, but a car wash might be a different story. These lights were designed for RVs and they are not normally ran through car washes. If the car wash were a touch-less model then you should be fine, but a car wash with the mops that twirl would most likely cause an issue with the lights protruding from the side of the shell. Another option may be to install a flush mounted...
