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.

4-1/4" Diameter, waterproof, incandescent light provides backup light function for trucks or trailers. Shock-proof socket protects bulb. Flush mount with grommet (sold separately). Accepts standard 2-prong plug. Includes 1 bulb.These lights are great, they are very clear and bright! They are being used as reverse lights on my RV!! I only needed one but went ahead and purchased two to replace both, and I am glad I did!! Was very easy to replace, female plug just plugs right in with no problems!! I have enclosed a picture of front and back of lights, to show clearness and to show plug area!
Hard to find item delivered promptly at a good price. A necessary item for my Gulfstream RV. You need stoplight and backup lights! I ordered and received both!
FYI, good replacement for GloBrite Tail & bkup 9551 & 9547
Prompt Delivery
I don’t like buying things on line normally but I thought to give this site a try, my light installed without any problem and also was delivered on time!
Great site will order again
Good prices an fast delivery.
The backup light fits my 2006 motorhome perfectly and works well. In fact, it is so much brighter than my other backup light that I am thinking of ordering another one. Etrailer's service was first rate. The package came when promised and was packed very well with plenty of cushioning to protect the light.

Still working great.
Purchased a pair of these after one light burnt out on my 2005 coachmen camper. Both easily installed assisted by a bit of silicone sprayed on the exhisting rubber grommets. Good as new !!!
Prompt shipping and no issues with the products I ordered. Product was exactly what I needed and at a very good price. I would do business with etrailer again.

No issues. Still working fine......
Great replacement light for an older motorhome, we have a Thor Tuscany and these were perfect to update the lights
Clear backup lites ordered for flatbed truck bed were replaced & plugged in, fit perfect, no hassles. * I'd order from this company as needed again.
Everything I needed to update my trailer was here. As I was preparing the trailer to put the new parts on, the mail carrier arrived and put them in my hands. All the parts were a direct replacement.
Plugged right in, a direct replacement.

I traded in the RV a few months ago but the light still looked great when I did.
Product came swiftly. Was as described.
These lights are nice and bright, compared to the old ones.
I ordered back-up lights and they arrived very quickly. Finding "etrailer.com" on line has been very illuminating.
these lights and mounts give me the old school look I wanted at a reasonable price. They have worked perfectly.
The light assembly is excellent quality. Heavy duty construction and fit the grommet and frame perfectly. The shipping was extremely quick, and the price just right. Would recommend etrailer.com highly.
This lite is like the OE,,and I did not have to order from the dealer.
E trailer are the only people I will order from on line.,,thanks
Excellent product-fantastic customer service! Follow-up is like none other. Will by again.
I had problems finding these tail lights, found them here at a very very reasonable price, exactly the one's I needed. Fast shipping and came well packed. Would definitely purchase here again! , highly recommended.
product was as advertised and promptly delivered. The fit was very tight for my Winnebago motor home but it worked fine. The exit for the wiring comes off the bottom instead of the side. That was my fault for not checking. I made it work.
Just what I ordered...Fast service..... always good from etrailer!
Perfect replacement for original equipment, works great. Thank You
Nice lights. Easy to install. Very durable and affordable
