Exactly what I needed for my trailer. Make sure the lights are pushed into their designed location properly. I lost a light because it wasn't seated properly. The metal is thick enough to take a really good weld. 873622

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. 736892

by:

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. 691414

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 etrailer.com, their knowledge and advice has been invaluable. 665944

  • Adding LED Lights To A Hollywood Racks Sport Rider SE 4
    We have definitely seen customers do this and modify racks like the EasyFold # TH903202 before using the LED kit part # 98174LED and the brackets # BK70BB to mount. You will also need some self-tapping screws # FA1131822, or drill and use the hardware of your choice to mount the brackets. Doing modifications on the Sport Rider SE 4 # HR1400Z can cause a voiding of the warranty so that's worth checking out with Hollywood Racks before taking this on. Another option to consider that...

  • Bracket and Grommet for Optronics Light STL72RB
    There is a way to use the bracket with a light that is just like the Optronics LED Trailer Tail Light # STL78RB although this particular light has a built-in flange and would not work with a bracket. If you take a look at the accompanying photo you can see how this light is designed to install. Instead you can use Optronics LED Trailer Tail Light # STL72RB which is the same light without the built-in flange and mount it with Grommet # A70GB and Bracket # BK70BB. I have added links...

  • Mounting Hole Size of the Optronics Trailer Light Mounting Bracket 6-1/2 Inch Oval Trailer Lights
    I went to our warehouse to get the Optronics trailer light mounting bracket # BK70BB to provide the measurement you need. The diameter of the mounting hole is 0.375 inches with a digital caliper. Using a tape measure it is 3/8 inches. I included a video and diagram showing you the measurements.

  • Does Light Kit part # 20174 Fit Brackets part # BK70BB
    Yes, the Light Kit part # 20174 that you referenced does fit the brackets part # BK70BB that you also referenced. The Y portion of the harness that runs to each light assembly is 3 feet long and the portion that plugs into the 4-way is 6 feet long.

  • How to Install Tail Light and Grommet into Trailer Light Mounting Bracket # BK70BB
    I went out to the warehouse and pulled a # BK70BB bracket, a 6 inch oval tail light and the A70GB grommet. I found that it is much easier to install everything if you push the grommet fully into the bracket until it is fully seated and then push the light into the grommet until it bottoms out. At that point, you will have a fit tight enough that the lamp is securely held in place. Make sure the grommet is pushed FULLY into place before inserting the lamp.

  • What Light Works with the Trailer Light Mounting Bracket Part # BK70BB
    Yes, for the Trailer Light Mounting Bracket part # BK70BB you can use part # ST70RB (incandescent) or part # STL22RB (LED) for the light, part # A70GB for the grommet, and part # A45PB for the wiring harness.

  • How Thick is the Trailer Light Mounting Bracket for 6-1/2" Oval Trailer Lights BK70BB
    I went out to the warehouse and pulled bracket # BK70BB to measure it for you. The bracket is 0.079 inches thick which is a little more than 1/16 of an inch. I have linked a video review of this light bracket for you.

  • Testing Trailer Wiring Circuits to Determine what Wires Run to Running Light Circuit
    You are going to need to verify what the circuit each of the wires you have on your trailer carries first since not all of the wire colors you mentioned are standard. Use a circuit tester like part # PTW2993 to test them while the different taillight functions are applied. The circuit that is hot when the running lights of the vehicle are on is the circuit to use for the running lights. I attached a help article that has standard trailer wiring diagrams for you to check out as well.

  • Parts Needed to Add LED Lights to Thule EasyFold Bike Rack
    The Thule EasyFold XT 2 Electric Bike Platform Rack # TH903202 that you referenced doesn't have taillights built into it. It's also not a normal requirement to have to add trailer lighting to a rack that has a cover but we have seen people add lighting to bike racks and cargo carriers before. You'd be modifying the rack to the point of voiding the warranty but you could use the LED kit part # 98174LED to add the lights and then use the bracket # BK70BB and you'd be set.

  • Solution for Blocked Tail Lights When Using Thule EasyFold XT Bike Rack
    I do have a solution for you, but Thule doesn't offer a light kit specifically designed for your EasyFold XT bike rack, # TH903202. One option is to use the Rola LED Light Kit # 59516 along with two mounting brackets # BK70BB . This would most likely require permanent modifications to your EasyFold though, since you'd need to drill holes to mount the lights on the rack itself. You could try to use zip ties to attach the mounting brackets to your bike rack, but it wouldn't be the most...

  • Recommended Parts and Wiring for Adding LED Lights to Aluminum Cargo Carrier with Ramp
    Thank you for all of the helpful information! I do have a few different options for you to add LED lighting to your scooter carrier that resembles the MaxxTow 27x47 Cargo Carrier # MT70100. You can definitely use the Optronics Streamline LED Trailer Tail Light # STL79RB with wiring like the Hopkins Endurance # HM38134 by just using heat shrink butt connectors # DW05744-5. Since your carrier is aluminum you will need to cut off the eyelet on the ground wire and splice it to the white...

  • Can Tail Lights be Installed on Kuat Sherpa 2.0
    Thank you for the purchase of the Kuat Sherpa 2.0 # SH22B. Since your right turn signal is being obscured you could very possibly use the Thinline LED Trailer Tail Light # STL59RB with a 4-Way pigtail like part # HM38134 but I have a different recommendation for you that I believe is a bit simpler to install and will look better since that strip can only carry one turn signal function. I recommend using the Light Kit # 20174 with 2 of the Bracket # BK70BB. The 4-Way connector is already...

  • Cutout Dimensions Needed for Flush Mount Oval LED Trailer Lights
    The Optronics LED Trailer Tail light - Stop, Tail, Turn - Submersible - 10 Diodes - Red Lens # STL72RB will use the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB for mounting. With this combination the opening you need to cut is a 6-11/16" long x 2-5/8" wide hole like you can find on the mounting bracket # BK70BB. You may want to get the bracket as a stencil to give you the perfect fit. You will also need the wiring pigtail # A45PB for each light. The kit you mentioned #...

  • Best Bracket and Light To Add To Hollywood Bike Rack
    I recommend to use the 6-1/2" oval bracket part # BK70BB with the lights of the Rola LED light kit part # 59516 because the 6" oval will be a tight fit. They will fit perfectly into the 6-1/2" oval bracket with the grommets on the light. I have attached a photo for your reference. The brackets will require self tapping screws or zip ties to hold them on. Another option is to use the MaxxTow Magnetic lights part # MT70097 on the vehicle itself instead of trying to attach them to the...

  • Solution for Adding Lights to Thule T2 Bike Rack Both in 2-Bike and 4-Bike Configuration
    The etrailer.com LED Light Kit # 98174LED and Bracket # BK70BB that you referenced seeing will work great for your Thule T2 Classic Bike Rack. It includes an 88" long offset y-harness (46" length for the driver side portion) that will be long enough to reach the Pilot's 4-Way when using the T2 in its 2-bike configuration and you could add a simple extension loop when you are extending out the rack in its 4-bike configuration. We have these loops available in various lengths, such as...

  • Light Kit Solution for etrailer.com Cargo Carrier # E98874
    What I recommend for etrailer.com cargo carrier part # E98874 is light kit # 20174. To mount the lights you will also need 2 of bracket # BK70BB. You can use self-tapping screws to secure the brackets to the top, rear rail of the carrier. This set up is the most cost effective option. It would plug into a 4-way trailer wiring connector.

  • Could Rola Cargo Light Kit # 59516 Fit Carpod Cargo Carrier
    The only way I can recommend fitting the light kit part # 59516 to the Carpod Carrier part # M2205-01-02 you have would be to use the brackets # BK70BB to attach the lights to the bottom of the carrier. In the picture I attached you can see a similar way this bracket was used with the light kit.

  • Replacement Fender and Light Mount for Tow Dolly
    The Fulton Single Axle Trailer Fender with Top Step - Black Plastic - 14" Wheels - Qty 1# F008554 is a great fender to replace what has broken on your current tow dolly. You can use the Galvanized Steel, L-Shaped, Bolt-On Brackets for Plastic, Single-Axle Fender PF775X21W - Qty. 2 # PF775-BKT-2 for additional support. The bracket # BK70BB is not wide enough to mount to the fender without altering the mount so I recommend cutting the hole in the fender and using grommet # a70gb for your...

  • Light Kit Recommendation for Hollywood Rack E-Bike Rack # HLY84FR
    We don't have anything custom fit to allow you to install lights on your Hollywood Racks SE E Bike Rack part # HLY84FR but the part # 98174LED is an LED light kit for cargo carriers that would be the best starting point we could offer. You could use the brackets # BK70BB to secure the assemblies to the rack with self tapping screws like part # FA1131822.

  • Keeping the Tail Lights Visible When Using the Freedom SuperClamp EX # SA4025F on a Subaru Outback
    Aside from mounting magnetic lights, like part # TL21RK, on the top of your Subaru Outback your best bet would be to figure out a way to secure a light kit like part # 20174 to the Saris Freedom SuperClamp EX # SA4025F. We do have mounting brackets like part # BK70BB which may help but there isn't a kit that is made to fit with bike racks.

  • Way to Add Trailer Lights to K2 Motorcycle Carrier K2TMC201
    The towing capacities for a 2012 Ford F-150 range from 5,500 to 9,400 lbs depending on how it is equipped. The tongue weight capacity would then be 10 percent of the overall capacity so your truck would have a tongue weight capacity from 550 to 940 lbs most likely. We have a light kit that could possibly be made to work on the # K2TMC201, part # 98174LED. You would need a pair of brackets as well for mounting the lights below the carrier. For that you would need part # BK70BB.

  • Recommended Cargo Carrier for 2015 Mazda3 Hatchback
    You can use a cargo carrier with your 2015 Mazda3 hatchback but it will need to be a fixed carrier and not a folding carrier. The reason for that is the only trailer hitch that fits your '15 Mazda3 is a Class I hitch that requires the stability that a fixed carrier offers as opposed to a folding carrier. For a hitch I recommend the Draw-Tite # 24914 which fits your hatchback and is a Class I hitch with a 1-1/4" receiver and 200 lb tongue weight capacity. What this means is the combined...

  • Mounting Grommet, Bracket and Plug for Light Guide LED Backup Light BUL602CB
    Yes, we do have a mounting bracket and plug for the Light Guide LED Backup Light # BUL602CB. This light can use rubber grommet # A70GB along with metal bracket # BK70BB for mounting. For wiring you can use pigtail plug # A45CB. I called Optronics to confirm the number of diodes and it is indeed 12; but four of them are located behind the narrow center band in the middle of the light.

  • Wiring Pigtail Functions for Optronics LED Trailer Tail Light
    I'm not 100 percent sure what you are referring to in regards to the wire, but it sounds like maybe you need to know the functions of the pigtail harness that is needed for the Optronics LED Trailer Tail Light # STL72RB. This light uses a 3-wire pigtail, either 3-Wire Pigtail # A45PB or Right Angle 3-Wire Pigtail # A47PB. This pigtail has three wires, a white, black, and red. The white wire is ground, the black wire is the power, and the red wire is the brake/turn signal, which is...

    Only the European version of the DoubleTrack has the light kit, but you should note you can only order that bike rack in Europe. You can't order it and have it shipped to an American address so tracking it down will be difficult most likely. We have had people install lights on an EasyFold # TH903202 though. For that you'd be modifying the rack to the point of voiding the warranty but you could use the LED kit part # 98174LED to add the lights and then use the bracket # BK70BB and you'd...

  • Parts Needed to Add Light Kit to Curt Cargo Carrier # C18153
    What I recommend for Curt cargo carrier # C18153 is light kit # 20174. To mount the lights you will also need 2 of bracket # BK70BB. You can use self-tapping screws to secure the brackets to the top, rear rail of the carrier. This set up is the most cost effective option. It would plug into a 4-way trailer wiring connector. Which if you didn't have that on your 2014 Hyundai Tucson you'd need the part # 118501 as well. I attached an install video for this kit for you to check out as well.
