Video Transcript for Review of Buyers Products Tow Bar Wiring - Bypasses Vehicle Wiring - 337TL257M

Today we're going to take a quick look at the Buyers Products Heavy Duty Magnetic Tow Lights.Now, whenever you're flat towing a vehicle, you'll need several different components: your tow bar, base plates, your safety chains, and your lights. These are going to mirror the RV's lighting functions onto your towed vehicle. That way, you stay safe when you're out on the road, and you also meet all the DOT requirements.Now, these lenses are going to come in a handy carrying case. It has a handle on the top. Makes it easy to stow somewhere in a compartment below your RV, maybe stash it behind one of the seats in your cab. Keeps them up and out of the way.

And if you don't want to make any changes to your towed vehicle, this is going to be an easy way to bypass that.Basically, you're just going to have these running from the back of your RV to your towed vehicle. These are just going to be magnetic lights that sit on top of your towed. We'll have our incandescent bulb. It's pretty easy to change out the bulbs if and when they go bad. There's a little wire keeper that goes around the lens.

You pop that out, lens comes right off, you can change that bulb no problem. Pop the lens back on, and then fit that wire keeper back into place. That can be a little tricky. You just kind of have to get it to fit in the groove around the outside .. or, around the inside lip of the light housing itself.

So, as far as maintenance goes, not too bad.The way this stays in place, again, is going to be a magnet on the bottom. Those have a felt covering so you don't have to worry about any scratches or scuffs to your vehicle. We'll have our wires that are going to go back . or, go up the front to our RV. Now, this is going to be 30' long in all.Something to keep in mind with this.

Even though you're not going to be making any changes to your vehicle's wiring . You don't have to worry about voiding any warranties, getting in behind your tail lights, anything like that. The thing to keep in mind that's kind of a down side to the magnetic lights is that these wires are going to be going over the top of your vehicle or running somewhere on the outside. So, there's a good chance that these are going to rub up against the paint. Over time, it could cause some abrasions there. Something to keep in mind.If you're towing once a year, not going for super long distances and you just need a quick fix, this is going to work out well. It can also work well for towing situations whenever you're just a recovery vehicle, maybe you run a towing service, something like that. Makes it a little bit quicker and easier to use.As far as the other connection, we'll have a 4-pole round and a plug so you can get all those functions on your towing vehicle wired up. You'll just undo this Phillips head screw, it's a small Phillips head screw, that'll give you access to all the terminals so you can get that wired in to your towing vehicle. Whenever you're ready to hook up, you'll just plug it into that housing. Make sure you line up the pins. And then there's a pin and a hole that will line up and keep that cover in place and also prevent the wire from backing out accidentally. It has a spring going over the end of that cord to help give it a little bit more flexibility and rigidity so that you don't wear this out too quickly, so it doesn't get bent or kinked or anything like that.Overall, this is going to be a good way to stay safe on the road, let other drivers know when you're making stops and turns and meet all those requirements to stay within compliance. These do meet DOT requirements, and it'll give you all our turn signal, brake, and tail light functions. Easy to set up. You just plop these down on top of your vehicle, plug in your cable, once you have that wired in, and you're good to go.As far as the dimensions for our lights, these are going to be pretty small. It stands about 6" tall, about 6, yeah, 6 right on. The diameter of the light is about 4-1/2". The base, it's kind of a triangle shape, it's about 4-3/4" wide by about 3" deep. The lens housing is about 2" deep.Whenever we're done with it, we just pop that together, get everything to fit in there. Whenever you have this hooked up, you won't have to worry about that plug hanging out in there. That won't take up that much space. Then it all closes within our case. Then this is going to be about 14", about 14-7/8" wide, excuse me, 14-5/8" wide by 9-3/4, and it's going to be about 4-1/2" thick. It does come with some instructions to help you get your plug installed so you can match up all your wiring functions.And with that, that's going to do it for our look at the Buyers Products Heavy Duty Magnetic Tow Lights.

Exactly what I wanted

- 337TL257M

I opened the box and the first thing I noticed was how sturdy and well built it was. I actually bought this because I have a large cargo basket on the back of my Ford econoline van and I wanted Some lights that I could attach to it when making long distant trips that I could plug into my hitch light adapter. It’s perfect. Would recommend this product in a time people are looking for value for their money. Cheers.

  • Heavy Duty Magnetic Towing Lights for Flatbed Trailer Towed by 2017 Ford F-350
    It sounds like you're trying to add some lights to a flat bed trailer being towed by a 2017 Ford F-350. If your 2017 Ford F-350 has a 4 way round pin plug installed (or you're willing to do some wiring), you can use the Heavy Duty Magnetic Tow Lights # 337TL257M which comes with a 4 way round pin plug and socket to install on your vehicle. With that being said, I have a solution for you that won't require any additional wiring work. I recommend using the Heavy Duty Magnetic Tow Lights...

  • Plug-In Tow Lights For A 2012 Mini Cooper
    Instead of using the Heavy Duty Magnetic Tow Light Set # 337TL257M, which will require a 4 way round connector, I recommend the more common Heavy Duty Magnetic Tow Lights # TL21RK which will utilize a 4-flat trailer connector. If you do not have a 4-flat trailer connector, you can add one with # 119250KIT, which will plug directly into your vehicles factory wiring.

  • Connecting Magnetic Tow Bar Lights With 4-Way to Motorhome With 7-Way
    We have some options for you to connect magnetic tow bar lights to a motorhome connector (which should be a standard RV 7-way), though there isn't an adapter to go from the 4-round on the Heavy Duty Magnetic Tow Light Set # 337TL257M. While you could do some cutting and splicing to get it to work, the much easier option is to go with a magnetic light set with a 4-flat, the Roadmaster Standard Magnetic Tow Lights # RM-2120. There is an adapter that will go from a 4-flat to a 7-way, so...

  • Can You Use the Buyers Heavy Duty Magnetic Tow Light Set 337TL257M with a 7-Way Connector
    I do have an option for you but if you wish to use the Heavy Duty Magnetic Tow Light Set part # 337TL257M you'll need to remove the seven way blade style trailer connector on the tow vehicle and install the included four way round as we don't offer any adapter for this. That said, if you don't want to splice you can use the Roadmaster Standard Magnetic Tow Lights part # RM-2120 with an adapter like the Pollak 7 Pole to 4 Way Connector Adapter part # PK12716.

  • Availability of Adapter to Go from 4-Pole Round on Trailer to 4-Pole Flat on Vehicle
    I do have a couple options for you, but there isn't an adapter to go from a male (trailer end) 4-pole round to a female (vehicle) 4-pole flat or even a 7-way. So, you could either make your own adapter using part # PK11410 and # HM38138, if you do not want to modify the harness on your magnetic trailer lights, or you could simply replace the 4-pin round connector on them with part # HMC20031, which is going to be the most cost effective.

  • Can 2020 Subaru Crosstrek With Manual Transmission be Flat Towed and Parts Needed
    According to the owner's manual I looked up online, your 2020 Subaru Crosstrek with manual transmission can indeed be flat towed. In regards to the parts, they aren't additions, they are necessary in order to safely tow, and for things like a supplemental braking system, the law in most states. Flat towing can be costly, but these parts are important in order to ensure everyone's safety. I will recommend the most cost-effective parts for your 2020 Subaru Crosstrek's flat-towing set up...
