Video Transcript for Review of Custer Tow Bar Wiring - Bypasses Vehicle Wiring - LIW-LDTL

Today we're taking a look at the Custer Wireless LED Tow Bar Light. This is a weatherproof LED tow bar light that provides your stop, tail, side marker, and turn signal functions for your towed trailer or vehicle.The tail light bar shines red. For your tail lights, you'll have three diodes that are illuminated. Then you'll have one on each side.Brake light, everything lights up, so it brightens. For your turn signal light, you will have the red light flashing on either side, depending on which turn signal is activated. Then again, your side marker lights will stay on to keep your towed vehicle street legal.It's a wireless design, which is one of the biggest benefits of this system.

It eliminates the hassle of running wires or cords every time you tow.The transmitter, which is this unit here, it plugs directly into a four-pin socket. Then all you have to do is turn the light bar on, which there's an on and off switch. It's sealed back here, so it's protected. You just turn that on, and that allows you to use the lights as needed. Then you can turn them off when they're not in use, so that way you can conserve battery power.Now, this does feature a charge port right here.

And it comes with a charger. The rechargeable battery charges with the included 12-volt DC accessory socket.A green LED will illuminate when the unit is charging. When it's powered on, both turn signals will illuminate for approximately two seconds, showing that the batteries are fully charged.If the left turn comes on only, it means a partial charge. If neither turn signal lights up when you turn it on, then you need to charge your unit.Please keep in mind, with this unit, you cannot overcharge the battery in the light bar. It's a special battery, it cannot be overcharged.

So you can keep the bar on the charger when it's not in use.It's a LED system. LEDs make great replacements for incandescent lights. They last longer, they burn brighter, they're much more efficient. You don't have to worry about changing bulbs, and you don't have to worry about brittle filaments.The unit on the bottom has heavy-duty magnets on the base to provide a secure grip. These offer up to 90 pounds of pull, and they're rubber coated so they won't scratch or damage your vehicle's surface, or whatever surface they come into contact with.And then, again, weatherproof design.

We have a weatherproof exterior, which allows you to keep the light bar on your vehicle in all weather conditions. It's a durable polyethylene housing, so it won't warp or crack. And then the lights are all hard-wired, so the connections are all shrink-tubed. If for some reason moisture gets in there, it's still not going to affect the connection points.Pretty nice low profile design, for it being a light bar. Has a handle on top so you can easily move it around and take it with you. It is Department of Transportation compliant. Product's made in the U.S.A.A few measurements to go over with real quick, then we're going to hook it up to power, and I'll show you everything that it has to offer. So edge to edge, we're looking at about 23".From the very front of the unit to the very back, I did take a measurement from the outermost point of the LED lights, to the back of the charging port, and on and off switch. We have about a 5" depth right there.The box itself is just 4". And then when it comes to the overall height, bottom to top of the handle, it's about 4-1/2" tall; 3-1/4" tall not including the handle.I'm going to take this, I'm going to hook up my wires to it. I'm going to go ahead and turn on my light bar. You can see both illuminate, so that means we have a really good charge right now.What I'm doing is I'm just simulating as if I'm plugging this into a socket on a vehicle. And I'm going to go ahead and turn off our overhead lights so you can get a better look at it.This is the tail light function. You can see how we have the side markers illuminating as well. Now I'm going to hook up the turn, or I'll do the brakes first. You can see there how everything brightens up when the brakes are applied. Now I'll do turn signal. And I'll do the other one.Again, wireless design. This just plugs into the four-pin socket on your vehicle.That's going to do it for today's look at the Custer Wireless LED Tow Bar Light.

2017 Ford Explorer

I use the light bar on my SUV towed behind my RV. The towed vehicle is a $50k SUV so I was not excited about tapping into the wiring, or drilling holes in the taillight for an extra incandescent light in a well designed LED setup. I just have two comments. One make sure you zip tie the transmitter. If you are driving on 95 in the Northeast it will vibrate out. I am glad I thought of it or I would have been very unhappy. Second, you can not tell if the light runs out of juice. If it was not for irate truckers honking I would not have known. Be ready with a backup power supply in case your driving day includes a 3 hour delay due to accidents. Otherwise it has clung well, worked great and is very bright. I would recommend this product for any tower’s 455217

2018 Ford Edge

This is the best way I've had lights on the dinghy. I've been towing for 30 years. It's great not to have to get into the vehicle wiring. 551811

2005 GMC Envoy

2015 Buick Enclave

I just received the Custer Smart Light from etrailer yesterday. Charged the light bar for a few hours as recommended then mounted it to the roof of my SUV and plugged the transmitter into my motorhome. The light bar works as advertised. Time will tell if this item holds up to about 8K miles of towing per year. If all is well after a years use I give it 5 stars. 402632


Custer light Bar works great 9K miles of use without a single issue... 5 Stars!!

Do you have a question about this Tow Bar Wiring?

  • Equipment Needed to Flat Tow a 2015 Jeep Grand Cherokee
  • All of the equipment that you will need to properly flat tow/dinghy tow your 2015 Jeep Grand Cherokee will be base plates, a tow bar, tow bar wiring for working lights, safety cables, and most states now require a supplemental braking system be installed on any vehicle that is being towed. For your Grand Cherokee I recommend going with the Blue Ox Base Plate Kit # BX1128. I like the Blue Ox systems because you can detach the tabs so that your Jeep has a much cleaner look when not being...

  • Availability of Wireless LED Tow Light that Uses a Rechargeable Battery
  • The exact thing that you just described is the Custer Wireless LED Tow Light # LIW-LDTL. It uses magnets to install on the towed vehicle and has a rechargeable battery so you to not have to purchase AA or AAA batteries to power it. For the light functions to work you will simply need to plug in the wireless transmitter to the 7-Way on the back or your RV or tow vehicle and then flip the switch to the "on" position on the light bar.

  • Recommended Parts to Dinghy Tow a 2017 Chevrolet Sonic LT Sedan
  • I have the perfect setup to dinghy tow your 2017 Chevrolet Sonic LT. For a tow bar I recommend using the Blue Ox Base Plate Kit, part # BX1703. This kit does not require any welding and has base plate tabs that can be removed for a very clean look when you are not towing your Sonic. The next thing that you will need is a tow bar. I really like the Blue Ox Alpha, part # BX7365, for this setup because it works well with the base plate kit and it comes with safety cables. This tow bar...

  • Installing a Wireless LED Light Bar for Towed Vehicle Lighting
  • I might have a solution for you. You will need to replace the current 7-way trailer connector on the RV with # HM48470 that has both a 7-way and 4-way connector. Then you can use the wireless LED light bar # LIW-LDTL plugged into the 7-way with your dolly plugged into the 4-way. You'll also need a 12-volt socket in the cargo area of the vehicle if there isn't already one. You can use # RM-9332. You'll then need to figure out a way to mount the light in your vehicle's window, like...

  • Will Custer Wireless LED Tow Light Still Work when Plugged in and Charging
  • I spoke with my contact at Custer about the Wireless LED Tow Light # LIW-LDTL. I learned that it can function while it is plugged in and charging at the same time. However, it charges via a 12 volt power outlet on a vehicle and since it is meant to be used on a vehicle that is being towed there are a couple of potential issues that could arise from this set up. First, the 12 volt outlets on a vehicle may not have power when the vehicle is turned off. And if the outlet does have power...

  • Can Front Mount Trailer Hitch and Base Plates be Installed on 2001 Jeep Cherokee at the Same Time
  • With base plates installed on your 2001 Jeep Cherokee, # 1418-3 or # 1418-1, you will not be able to also install front mount trailer hitch # 65009. The issue is that both the base plates and the hitch install in the same place and occupy much of the same space so both cannot be installed at the same time. The same goes for Curt hitch # 31084. Neither the base plates nor front hitches are designed for or rated for being stacked or sandwiched. They are all meant to be in direct contact...

  • Base Plate for 2004 Jeep Liberty Thats Compatible with Reese Tow Bar
  • As long as your Liberty doesn't have a brush guard on it, the Roadmaster # RM-521423-5 base plate kit would be a good choice. If you DO have a brush guard, use # 521426-1. In order to be compatible with your Reese tow bar, you'd also need an adapter like part # RM-025. I'm not sure which Reese tow bar you have, but keep in mind that some of the Reese towbars have a limited speed rating of 45 mph. The # 40602 bracket you referenced is more suited to something that would have a completely...

  • Recommended Wireless Magnetic LED Tow Light
  • We carry the CusterWireless tow light system # LIW-LDTL that do not splice into the vehicle wiring as you said you wanted. We do not carry the Pilot lights you mentioned. The great feature about the # LIW-LDTL is that it is a magnetic light and you only have to be concerned with one area to attach it to. This system has a charging cord for the light, where the Pilot system uses 6 AA batteries that can be a hassle when the batteries go dead.

  • Can RV/Tow Vehicle Be Spliced Directly Into 2017 GMC Sierra Tail Lights without Using Diodes
  • If you were to wire in the 2017 GMC Sierra 1500 tail lights directly to the tow vehicle there could be back feeding problems which could damage electrical components even if the battery is disconnected. There could also be shorts when the truck is not being towed and its lights are used. Using a diode system such as # TR118821 prevents that from happening. If you do not like the idea of tapping into the tail light wiring and adding diodes another option is a wireless and/or magnetic...

  • Recommended Tow Bar Setup for 2013 Mini Cooper

It is very easy to maneuver and it comes with the safety cables for added security when driving down the road. Next you will want your base plates. Blue Ox has their Mini Cooper Base Plate Kit # BX1307 which works really well with the Alpha tow bar. This kit is very well hidden. You can remove the arms...

  • Equipment Needed to Flat Tow 2001 Chevy Tracker Manual Transmission 2WD
  • According to my research, the 2001 Chevy Tracker RWD w/ manual transmission is capable of being flat towed without modification, however it's not recommended to tow the vehicle above 55 mph. Your motorhome would need a hitch and a trailer connector at the rear. For the vehicle, you'll need a tow bar, base plates, wiring so the vehicle taillights work along with those on the motorhome and a supplemental braking system. The Blue Ox Alpha Tow Bar, part # BX7365 is an excellent choice...

  • Tow Bar, Base Plates and Flat Towing Accessories for 1996 Geo Metro

The Blue Ox Adventurer you referenced, part # BX7322 would work fine. For a base plate that bolts to the front of the vehicle frame and provides an attachment point for the tow bar, you could use the Blue Ox # BX3507 (as long as your vehicle isn't a GTI model.)

  • Tow Bar Cover for RoadMaster StowMaster and Parts Needed for Flat Towing a 2017 Chevrolet Spark
  • If you are using the RoadMaster StowMaster # RM-501, then the Tow Bar Cover is part # RM-052-3. For brake light wiring I recommend using the Custer Wireless LED Tow Light # LIW-LDTL. This is a magnetic and wireless brake light which makes it very easy to install as opposed to a kit that you would have to hardwire into your Spark. Other equipment you would need to flat tow your 2017 Chevrolet Spark will be: Blue Ox Base Plate Kit - # BX1725 RoadMaster Tow Bar to Blue Ox Brackets...

You will need to check your owner's manual to make sure that you follow any specific instructions on flat towing as well. For base plates I recommend using the Blue Ox Base Plate Kit, part # BX3728.

  • Fit of Roadmater Base Plate Kit # 310-3 on 1995 Nissan Altima
  • If your 1995 Nissan Altima has the factory installed driving lights in the front bumper, Roadmaster states that the # 310-3 or the # 310-1 are not a fit. It MIGHT be possible to remove the OEM driving light assemblies so the base plates will fit, but this has not been tested, so we cannot say with any certainty that it would work. You'll need to check with your owners manual or with Nissan to determine if your vehicle is capable of being safely flat-towed. In addition to the base plates,...

The adapter will allow your Demco Aluminator, Excali-bar or Kwik-Tow towbar to work with the Roadmaster base plates. To complete your flat towing system, you'll also need safety cables like # RM-643. You will also need a lighting solution so the lights on the towed vehicle work in tandem with those of the RV. Custer offers a simple wireless solution, part # LIW-LDTL.

  • The bulb and socket kit # RM-155-2 is not one of the tow bar lighting systems that is recommended for your 2015 Jeep Grand Cherokee (it doesn't fit) so I do not recommend using it. For another option that bypasses the vehicle wiring you can use a magnetic light kit such as # C-ATL20A or EZ mount kit # EZT20B at the rear hatch. We also have wireless options # NV-5164 and # LIW-LDTL.

The tow bar has a 10,000 lb capacity, so it would work fine with either vehicle. To flat tow either vehicle, you will need a tow bar, base plates, safety cables, a lighting solution so the lights on the two vehicle operate along with those of the tow vehicle and a supplementary braking system.

Custer offers a wireless magnetic mount tow lamp, part # LIW-LDTL. Installation couldn't be simpler. Plug the transmitter into the 7-way on the RV, and place the lights where they're wanted on the vehicle.

  • Can Anything Else be Plugged in when Using Custer Wireless LEDTow Light # LIW-LDTL
  • The 7-Way connector would be occupied by the transmitter for Custer Wireless LED Tow Light # LIW-LDTL. Any supplemental braking system you use that requires 12 volt power should get that power from the vehicle it is installed in and not from the RV. The reason is because if the vehicle gets disconnected from the RV the braking system will still have power allowing it to apply the vehicle brakes and avoid a runaway vehicle. If you can tell me the braking system you have I can look into how...

  • Installing Roadmaster 6-Diode Wiring Kit for Towed Vehicles on 2014 Ford Taurus

You can use a voltmeter or a simple circuit tester like part # 40376. There should be close to 12 volts being delivered to the taillights. Activate the left turn signal, and probe the wires until you find the circuit that makes the tester blink along with the turn signal. Do the same for the right turn, the brake light and...

It will still function like normal when it's actually plugged in and charging, but you will want to make sure that the 12V outlet in your towed vehicle still gets power when the vehicle is turned off for flat towing. I have attached a short video review on this tow bar light that you can also check out.
