Optronics BU45 Series Sealed 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 Backup Light for Trucks or Trailers Review

Today we're going to be reviewing part number BU45CB. This is Sealed, 4" Round Trailer Back Up Light from Optronics. The clear, round trailer light is going to function as a backup light. Featuring a sealed, waterproof housing and lens unit. Does have a corrosion resistant design. As well as a heavy-duty, long-life incandescent bulb.

The bulb is going to sit in a shockproof socket that's going to guarantee a long bulb life. It will accept industry standard, 2-prong plug. It does feature 3-prongs that are on the back side but only uses two functions. That's the only reason why the 2-prong plug is necessary. You can pick up a mounting grommet, sold separately, part number A45GB. The 2-wire pigtail that we'll be using today in our demonstration is available at etrailer.com.

Sold separately with part number A45CB. That's going to help you for a complete flush mount installation. The the mounting bracket is also available, you can find that underneath the related products with part number BK45BB. That's also going to be sold separately. If we go over the dimensions real quick, this is going to give us a diameter of 4 1/4", With a depth of right around 2". We're going to go ahead and hook it up to our external power source.

We're just going to take our 2-prong plug. Fit it into our mounting location here on the back side. You can see here that when we activate the reverse light, it's a nice bright signal. The incandescent bulb really puts out a strong signal, especially through that clear lens. That's going to do it for today's look at part number BU45CB. This is Sealed, 4" Round Trailer Back Up Light from Optronics.

  • Replacement Reverse Light for Ranger z521 Boat Trailer
    I have a solution that may work for you, but we do not currently have any 3" diameter submersible reverse lights. Have a look at the Optronics Backup Light # BU45CB which is a 4-1/4" diameter light that can be mounted to your trailer using mounting bracket # BK45BB. You will also need the 2 wire pigtail # A45CB to replace the wiring from your old lights and plugs into the back of this Optronics light. I've attached a photo that outlines the dimensions of the light to see if you can match...

  • 4 Inch Round White Trailer Backup Lights Needed for a Quick Loader Trailer
    Yes, we have the Sealed, 4 inch Round Trailer Back Up Light, # BU45CB, that has a clear lens and provides a white backup light. Along with the light you might also need a 4 inch round grommet, # A45GB, and a straight pigtail, # A45PB, or a right angle pigtail, # A47PB.

  • Can the Bulb Inside the Optronics Backup Light BU45CB Be Replaced
    Correct, the bulb inside the Optronics Backup Light part # BU45CB is not replaceable because this is a submersible light therefore sealed. I would not really call this bad engineering as it was designed this way for a reason. If you were to replace the bulb you would have to break the seal and then the light would no longer be submersible.
