Video Transcript for Optronics License Plates and Frames LP15SB Review

Speaker 1: Today we're taking a look at a trailer license plate mount bracket. This trailer license plate bracket is extremely strong and durable. It does a great job at creating a solid area for your license plate to be mounted. It is made of heavy duty steel, and it's zinc coated, or zinc plated to resist rust and corrosion. It can be used with stud mounted license plate lights, as well as tail lights that have a built in license plate light. So, it can be installed directly behind your taillight assembly.

And as you can see here, it angles down and provides a great area for mounting your license plate. And then the light would be able to shine down, illuminating the license plate area.A few measurements to go over with you real quick to determine whether or not this will work for your application. The overall length of the unit, measuring edge to edge, is about 8 7/16 of an inch to 8 1/2 inches. The holes for mounting the license plate, you can see these are elongated and their separated apart from one another on center. So, center on center, is about, I'm going to say about 6 3/8 inches apart.

Right in that area. The holes for stud mounted taillights. That's these two holes right here. These are separated on center by two inches. The holes for a standalone license plate light, these right here, are elongated and their separated apart from one another on center by 2 1/4 inches.

And those smaller holes right there are separated on center by and inch and a quarter. The gap located right here at the top, has a gap measurement of 1 1/8 inches wide by 1 1/8 inches deep.And it's put together really well. Again, steel construction, heavy duty design. And it does have protective coating to keep it safe from rust and corrosion. That's going to do it for today's look at the trailer license plate heavy duty mount bracket..

Trailer License Plate Mount Bracket, Heavy Duty Zinc Steel - LP15SB

Average Customer Rating:  4.9 out of 5 stars   (379 Customer Reviews)


Are you kidding? This metal license plate mount is rock solid and under $2. The holes are set up perfectly to fit the mounting bolts on my driver side trailer light and the position of the license plate when mounted allows it to be lit by the clear lens on the bottom of the trailer light when the running lights are on. Also, the bracket allows the mounted license plate (and frame) to just clear the rail of the flat bed trailer itself. Yeah, it's a perfect fit. Thanks, trailer!!


Sturdy material, but not completely universal. On my Carson trailer, I had to flip the bracket backwards since the indentation on the bracket come down far enough to allow for the trailer light box. Also, the hole line up tonattach to the light box was just off enough I had to force the bracket on. However, once I installed it, it was solid and so don’t fear it will come off on its own.


I think you will find these photos show a unique installation of your metal trailer license plate holder.
My Yamaha golf cart is street legal which requires a license plate. You will see in close up photo that the holder is used up side down for a custom fit.
Couldn't be happier. The plastic holder was not stiff enough so your holder is perfect.


I purchased two tag license frames, one for my boat trailer and the other for my trash/hauling trailer. Both trailers had plastic license holder frames and one broke on rough surface.


The product was exactly as pictured and described. I am extremely pleased and recommend retailer products to anyone.

It works great. Absolutely no issues at all. I would highly recommend etrailer products to anyone.
Robert - 04/25/2022


Excellent product description with relevant questions and answers from prior customers!


Much better than the plastic one that came with the lights on the trailer.


Very happy with my order once received. Only downside was it took a long time using USPS. etrailer responded quickly. USPS did not.


Both brackets arrived in great condition. There was an issue with the items being backordered from the manufacturer, however I was notified on their status weekly by Carol at eTrailer. Would recommend these items and eTrailer to any purchaser. Shout out to Carol for keeping me in the loop!


Excellent quality, easy online ordering and blistering fast delivery once again. Thanks


Old bracket was plastic and easily broke off. I Ordered a metal one from etrailer at a great price. I painted mine with some extra plasti dip I had laying around and riveted it where the old one was and it's better than new!


Great well made product just as advertised. No more lost license plates due to cheap plastic brackets. This metal bracket looks like it's going to last a a life time!


Great product at a great price. Took five minutes to install.

Mike, where did you get your old black plastic bracket that broke? I had the exact same one and I liked it and it worked for me. I cant find a suitable replacement and would like another one just like this. Thanks!

Not to good plate came undone and flew off my trailer . Had to buy another liscense plate .
Mike R - 03/13/2018


Fit perfect on the 7,000 lb utility tra iler.


Great price and fit nicely.


Fast. Great quality.


Everything that I have ordered from y'all has been perfect! Be ordering again I'm sure-I have quite a few trailers and such. Thanks again, Mark from Spicewood,Texas


Just fine.
What I expected


better than the cheap plastic bracket that came with trailer.


This metal plate bracket is well made and fits perfectly as shown on the video on my boat trailer. I love that they had the installation instruction video which helped me decide the purchase.


If you buy, do not select economy shipping unless you can go without the item for weeks.


Exactly as advertised. Sturdy metal br acket.


Products from etrailer are always good quality, thanks.

  • Recommendation for a License Plate Bracket for a Small Cargo Trailer
    I believe I have just the right license plate bracket for you. Take a look at the Trailer License Plate Mount Bracket, # LP15SB. It is just a little over 8 inches long at 8-7/16 inches. It is 4 inches tall. The center to center distance between the center slotted holes is 2-1/4 inches but can be 2-3/4 inches apart at the outside edges. The top most set of holes are 2 inches apart on center. I have included a picture showing the dimensions for you.

  • Angled License Plate Bracket Recommendation for a License Plate Collection Display
    I think a better option for you would be the Trailer License Plate Mount Bracket # LP15SB. This bracket has an offset that is pretty close to 90 degrees and since it is a metal bracket it can be bent to the desired angle if needed. You could also paint the bracket with spray paint if you wanted.

  • Stand Off Dimension of the Trailer License Plate Mount Bracket # LP10SB
    I went in our warehouse and measured the stand-off of the Trailer License Plate Mount Bracket # LP10SB that you referenced and found it to be right at 1/2 inch. The closest one we have with the 1-1/2 inches of stand off that you want is a metal one, part # LP15SB. This one has a 1-1/4 inch stand off dimension

  • License Plate Bracket for a 1992 Jayco Pop-up Trailer
    We may not have the exact same license plate bracket as the one you lost on your Jayco trailer. But we do have quite a few that you could likely use. Bracket # LP15SB is an excellent choice since it is metal and would be more durable and would not cause ground problems (if the tail light grounds through the mounting studs). It mounts on holes that are 2 inches apart on center. If you happen to need a hole spacing that is 1-3/4 inches apart then you could use # LP20SB. I have included...

  • License Plate Bracket Options For Tow Dolly
    I recommend using a license plate holder like part # LP15SB. You would need to find a suitable place to mount the bracket and probably drill through the fender or the frame to install this bracket. This bracket does not come with mounting hardware. We do have license plate brackets that are designed to be used with tail lights. I have attached a link to our product page for the brackets we offer. You may find one that will work with the tail lights on your dolly.

  • Does Optronics Heavy Duty Trailer License Plate Mount Bracket # LP15SB Include Hardware
    The Optronics Heavy Duty Trailer License Plate Mount Bracket # LP15SB does not include mounting hardware. You will need to re-use your existing hardware or choose new hardware. This plate mount is intended for full size license plates but you can check the included photo with dimensions to see if it will work to your satisfaction with a small plate.

  • Would the Optronics Trailer License Plate Bracket part # LP15SB Replace a Wesbar 003201 Bracket
    The Wesbar license plate bracket part number 003201 that you referenced is a universal license plate bracket just like the Optronics Trailer License Plate Bracket part # LP15SB. To see if the mounting holes would line up check out the dimension picture I attached. If the dimensions don't match up you could still make the bracket work pretty easily.

  • Legality of Operating a Car With the Rear License Plate Blocked by a Bike Rack
    Typically a bike rack will not completely obscure a vehicle's rear plates, and in our customers' collective experience this has not been an issue for law enforcement. On the other hand, a fully-loaded cargo carrier WILL likely block a rear plate entirely and this might be an issue. I suggest you contact the State Police or Highway Patrol in the states in which you will be travelling and simply ask them about this concern. In states that do not require a front plate, there may be greater...

  • Recommended Metal License Plate Bracket With License Plate Light Mounting Holes 2" On Center
    For a metal license plate bracket that will work with the 5-3/4" mounting holes and will still work with your license plate light that has 2" mounting holes you will want the Trailer License Plate Mount Bracket # LP15SB. The zinc plating will help to keep the bracket from rusting and is a great option for a boat trailer. I included a video of the # LP15SB for you to take a look at.

  • What's Easiest Hardware to Install License Plate Bracket

  • What Fascia Trimming is Required to Install the Draw-Tite Front Mount Hitch on a 2011 Chevrolet 3500
    The front fascia trimming that is required to install the Draw-Tite Front Mount Hitch on your 2011 Chevrolet 3500 is detailed in the installation instructions that I have linked for you. Basically, you will need to drill a square hole that is 3-1/4 inches by 3-1/4 inches. To begin measuring for the cutout, you will want to measure from the tow hook bolt center to the ground. Next, subtract 4-1/8 inches from that measurement, this will be the distance from the ground to the bottom of the...

  • Do Cargo Carriers Normally Obstruct Taillights and License Plates
    The Reese Carrier # 63155 that you referenced is 47 inches wide and should sit lower than the taillights of your vehicle (most likely). Mainly due to the width of this carrier it shouldn't interfere at all with the visibility of the taillights. You can measure the distance between your taillights to be certain. This carrier should sit lower and be too narrow to cause issue with that. Also, most likely the cameras that would take a picture of your license plate would be up above and the...

  • Metal License Plate Holder and Bracket for a 2012 Karavan Boat Trailer
    Metal license plate bracket # LP15SB would be a good option. The top most mounting holes are 2 inches apart on center. I included a picture showing the dimensions. We also have steel cover # LP20SB. I have included a picture of its dimensions as well. Being steel, it would not be as corrosion resistant as # LP15SB. Aluminum bracket # CE26053A is another excellent corrosion resistant option. Its mounting holes are 1-1/2 inches part on center.

  • Troubleshooting Turn Signals Not Working with Running Lights On on a Utility Trailer
    First, check the trailer wiring harness on your tow vehicle with a circuit tester, like part # 40376, and make sure all of the functions are working correctly without the trailer connected. Make sure to test with the running lights on and off to be sure. If it is not working correctly you will most likely have to replace the taillight converter. If it is working correctly, turn your attention to the trailer. It does sound like a weak ground, or a short circuit issue, because when you are...

  • Will the Curt Trailer Hitch Mounted Cargo Carrier # C18145 Fit a 2006 Acura MDX
    With the Curt cargo carrier, # C18145, installed, you should not have any problems opening the rear hatch on your 2006 Acura MDX. To be certain, you can take some measurements. Measure from the top of the receiver opening up 5-1/2 inches, and then out 6 inches from the center of the hitch pin hole. This is where the nearest part of the carrier will be to the vehicle when installed. I have included some links on the Curt carrier for you. Given the position of the license plate holder on...

  • Recommended Hitch Adapter To Use With Thule Bike Carrier And Provide Clearance For Taillights
    Using any adapters in the trailer hitch on your Rogue will reduce the hitch capacity by 50 percent. Since you are using your hitch for a bike carrier you may still be within the weight capacity of your hitch. If you have a 2-inch receiver opening I recommend an adapter like part # RM-076. This adapter offers a 6-inch rise or drop and may give you the needed clearance for your tail lights. We do not have an adapter with a rise or drop like this for a 1-1/4 inch receiver opening.

  • Will Curt Aluminum Trailer Hitch Mount Cargo Carrier Fit 2007 Toyota Tacoma and Block License Plate
    First, to determine if the Curt cargo carrier # C18100 will fit your 2007 Toyota Tacoma you will need to take a measurement. Measure from the center of the hitch pin hole on the truck straight back to the distance required to clear the rear bumper. If that distance is less than 5 inches then the carrier will fit when folded up and down. When folded up the license plate will be blocked similarly to the way it blocks the plate on the Tundra in the video I have linked. You can relocate the...

    If the cargo loaded on the etrailer Cargo carrier # e98874 come up to the bottom of the license plate on your 2014 Mazda CX-5 but do not block it then there shouldn't be any problems. You can add a license plate bracket to the back of this carrier using # LP15SB but you would have to drilling into the carrier. Otherwise you could just zip tie the plate to the back of the carrier but you would have to cut it off every time you were finished and it is not as secure as an actual bracket.
