Trailer Light Mounting Bracket for 6-1/2" Oval Trailer Lights, Steel - Black Powder Coat - BK70BB

Average Customer Rating:  4.8 out of 5 stars   (211 Customer Reviews)


Brackets seem to be good quality, and not flimsy metal at all. The lights fit nice in them, and not loose. They really look great on my Thule T2 Classic bike rack.
Warning though, if you dont pay for the more expensive 3 day shipping, your package will just sit there and get pushed back in the shipping queue for a week or more.


Used 2 of these to add a light kit to my Thule T-2 receiver bike hitch. East to mount and wire with optional lens kit. Adds extra safety with 2 29 inch bike hanging out the back.



After one year it is still working perfectly


Bought these brackets to mount two oval LED lights to my Thule Hitch mount bike rack. Rugged construction made installation easy. Well made product that I would highly recommend.


All products bought from have been as advertised. All products purchased are excellent. Products purchased are, Blue ox tow receiver, 6 inch drop/rise. A very strong, well made product. Also, a set of LED tow lights, for my scooter carrier. A 'Quiet hitch lock', which ensures no movement in my hitch at all. Lastly, a hitch plug, a little bit of 'whimsy', many thanks to the reps., at, their knowledge and advice has been invaluable.


Attaced trailer lights to a Thurle hitch, 2bike platform. When the plateform is lowered to the loaded position the lights are located on the bottom of the rearmost horizontal bar. The light on the left is attached to the hex bolt at the end of th bar and rhe other end of the mounting bracket is held to the bar by a zip tie which runs through the hole at that end of the bracket. On the right side There are 4hex bolts on that part of the bar. The bracket holes don’t match up to those bolts. I used the bolt closer to the center and furthest to the rear and drilled a new hole in the bracket to match the bolt in that line furthest to the end. Both lights are secure and as the picture shows helps to define the protrsion of the rack and hopefully will protect from a rearend crash.


Bracket and lights worked as I intended them to. I have to back my boat trailer into a dark barn and the lights help in doing so.


Worked well for my flatbed project
design and have held up against
Vibration and weather. Overall happy
With these brackets


A friend had this style on his trailer and they seemed to be trouble free, I could not buy these local for the price etrailer offers.
So I bought light, gromet, and pig tail. Very nice and easy to mount.


Just what I needed to add tail lights on my T2 Pro bike rack for added safety and peace of mind.


I had crushed one of the tail lights and I. Replaced it with this one and it was exact same thing. Thank you so very much and have a nice day


Exactly what I was looking for these are sturdy enough to attach with magnets as temporary towing lights for my historic vehicle. Thanks


The Brackets are made of rigid, high quality steel, with a nice powder coated finish. We used these brackets to add newer style lights to an old trailer. These saved us lots of machining and cutting time.


I have a Thule Easy Fold XT Bike Rake, which by the way is an awesome Bike Rack. It lacked one thing, Brake Lights. makes it easy to attach. Here is my installation which took about 30 minutes to install.


fit the back up light perfectly as advertised.
universal mount, mounts anywhere you can drill a hole or two.


Good fit and plenty of holes for vaious mounting applications. I welded mine on and the material is thick enough to be welded and hold its structural integrity mounted in any position.


Looks great on my trailer. thanks

Just like a TIMEX watch takes a licking


Great value and seemingly good quality. I opted to add stop lights with components reviewed on etrailer site. LED wiring with light kit is very problematic. Had to purchase a 12” 4 way extender. No way to do a neat, professional install due to the wire harness. Oh well, it’s installed. I would still do it again but suggest product management take control. . Love etrailer service.


Straight forward mounting. I used twist ties provided. Very secure. Drove 600 miles with no issues. Customer service was excellent


The bracket depicted in this review IS NOT the bracket I got. Disappointed. My bracket doesn't say etrailer nor did it come with screw holes as shown. I had to mount lights to bracket via zip tie. Again, disappointed.


Elcellent product and arrived early. Works just as advertised and looks nice on my Cargo Carrier. Just got done ordering more items. Great customer service department answered all my questions.


Was a great fit for the lights I purchased from [online]. High quality and made installation.a breeze.


They are a replacement for the ones that got into an accident and got bent up.


Works nicely with the lights.


I mounted a pair of these 98174LED lights to my Hollywood Racks Hitch Bike Rack- HR1450Z-E. They work great. It's nice to have the added protection of having an extra set of brake/tail lights when my mounted electric bikes cover and hide my Ford Escape tail lights.


First...I have used trailer hitches and other products from etrailer before...all worked and were relatively easy to install for a 74 year old, falling apart, fat boy.

I have no real complaints toward etrailer or those/this product.

I called before ordering this oval light mount to be sure it would fit the LED trailer lights I have and was assured all 4 holes lined up perfectly. My lights looked like the 10 led STL72R, but the mount had only two holes and only 1 hole lined up(see pictures)...the other was off by ~14" to 3/8".

In all fairness I don't know how old my lights are or who made them...nor do I know which light was used as a model or by whom at etrailer...

It is NOT a big problem and easily fixed and the mount is usable as is just by drilling an upper mounting hole and/or elongating the mount holes on both the light and mount and using washers to squeeze the flanges together.

A person can always hope that pieces and parts will fit perfectly but that isn't the usual happening especially with parts made who knows how many years apart and by how? many manufacturers.

I am satisfied.

This assembly will be mounted on a "trunk mount" attached to my Voyager Trike kit on my 2002 Moto Guzzi California Special Sport
