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.

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

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

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.

  • Wireless LED Tow Bar Light with Magnetic Base

  • How Would 2001 TJ Wrangler Custer Wireless LED Tow Bar Light # LIW-LDTL Fit Wrangler
    The Custer Wireless LED Tow Bar Light # LIW-LDTL that you referenced is designed to attach with the powerful magnets on the bottom of it either to the top of a vehicle or to the rear bumper. Looking at the rear of your 2001 Jeep TJ the best shot it's going to have at fitting properly is if you have a metal rear bumper you can set it on top of since the top is not metal. If you have other ideas let me know and maybe we can work out a better solution. I attached a review video for this...

  • How to Charge Custer Wireless LED Tow Bar Light # LIW-LDTL
    The Custer Wireless LED Tow Bar Light # LIW-LDTL does have a rechargeable battery and the only way to charge it is by plugging in the included 12V DC/cigarette style adapter charger. 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.

  • 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. Since this is made to be installed on the top of a towed...

  • 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.

  • Using the Custer Wireless LED Tow Bar Light on a 2016 Chevrolet Silverado 1500

  • How Many Hours Will the Custer Wireless LED Light Battery Last Between Charges
    The Custer Wireless LED Tow Bar Light # LIW-LDTL has a 4-8 hours battery life before it would need to be charged, so it's not really ideal for the use that you're looking for. With that said, if you could figure out a way to keep it plugged in to a 12v power source inside the tow vehicle you could likely make this work as you're hoping. You could also use a setup like the Roadmaster Standard Magnetic Tow Lights # RM-2120. Check out the attached video to see how easily it is installed.

    The transmitter for the Custer Wireless LED Tow Bar Light - Weatherproof - Magnetic Base - 23" Long - 7-Way Round Item # LIW-LDTL-7B gets it's power through the 7 Pole plug on the back of the RV.

    The only option for charging the Custer Wireless LED Tow Bar Light # LIW-LDTL-7B that you referenced is using the 12 volt cigarette lighter style connector that it comes with.

  • Is It Normal For Brake Light Of Custer Wireless LED Towbar Light LIW-LDTL-7B To Flash W/ Turn Signal
    It sounds like you are saying that when the brakes are pressed in your tow vehicle, and the turn signal is on at the same time, that the brake light on the Custer Wireless LED Tow Bar Light - Weatherproof - Magnetic Base - 23" Long - 7-Way Round # LIW-LDTL-7B flashes with the turn signal. If that is the case, then everything is working correctly. On a 7-way connector like this light is powered by the brake signal and turn signal are powered by the same wire so their functions will be combined....

    I wet ahead and checked out the transmitter on the Custer Wireless LED Tow Bar Light - Weatherproof # LIW-LDTL-7B, and was able to find out that this unit gets it's power through the 7-pole on the back of your RV. So when your RV has power to the 7-pole, and it is plugged in, the transmitter will send a signal to the light. This light does have an 3AH battery which can be replaced/charged that I recommend checking first, and it can be accessed from a panel at the bottom of the light. The...

  • Will The Custer Wireless LED Tow Bar Light Interfere With A Wireless Backup RV Camera's Signal
    The Custer Wireless LED Tow Bar Light - Weatherproof - Magnetic Base - 23" Long - 7-Way Round # LIW-LDTL-7B is most likely going to use a different frequency than your camera will. To verify for sure you can look up the mega/giga hertz of your camera's frequency and see if it matches the 914 megahertz frequency that this light will be on. If it does not match the frequency then you will have no interference issues.

    I contacted the manufacturer in regards to this question. Per the manufacturer the Custer Wireless LED Tow Bar Light - Weatherproof - Magnetic Base - 23" Long - 7-Way Round # LIW-LDTL-7B should be fine for several weeks after a full charge, if it is just sitting on the shelf. They recommend that if you use the light bar during the day, you should plug in the charger and get power to it during the night. That way it will always be ready to go. Once fully charged, the bar should last 6-8...

  • How to Use Custer Wireless Tow Bar with RV that has 6-Way Round
    The 4-way round connector is very rare and the 6-way round is somewhat common but more rare than 4-way flats and 7-ways so what that means is that we don't have an adapter for your configuration but I have a similar solution. We have a version of the Custer Wireless Tow Bar Light that uses a 7-way blade with the part # LIW-LDTL-7B which we do have adapters for like with the # 337TC1067P which plugs into your 6-way and converts to same connector as the tow bar.

  • Magnetic Versus Wired Magnetic Towing Lights For Long Road Trips
    If you were to go with the either the Custer Wireless LED Tow Bar Light 4-Way # LIW-LDTL or 7-Way # LIW-LDTL-7B I recommend getting 2 of these. That will allow you to have one in the cab charging while using the other one. As they have an expected battery life of 6-8hours per charge this will allow you to switch them out as you stop for gas or food. Otherwise the Magnetic LED Tow Light Kit # TLL21RK will provide you with 20' of wiring to use hard wired lights. These lights uses LED's...

  • Why Are My Trailer Brakes Activating/Deactivating When Plugged In/Unplugged to 7-Way Plug?
    If you are experiencing power at the 1 o'clock position on your 7-way, the issue most likely lies with the trailer's wiring. With this situation, it is important that the trailer wiring is correctly inserted into trailer's side 7-way plug so that the correct pins on the vehicle side can activate the correct corresponding pins. All that being said, I recommend removing your trailer's 7-way and using the Junction Box # 38656 to make sure that the wiring is on the correct pins on the trailer's-side...

  • What Does Custer Wireless LED Tow Bar Weigh and Can it Be Operated with 4-Way
    The Custer Wireless LED Tow Bar Light # LIW-LDTL-7B itself weighs less than 9 lbs. Because the connector for the light is a 7 pole, a 7 pole plug needs to be used but we do have an easy solution with the part # 37185 which you'd just plug your 4-way into and it would be set.
