I purchased this item to use while towing my bronco behind our motorhome. the charge only lasts 1-1 1/2 hours. the wireless connection is great, and the lights are great it's just the battery. this was a waste of money for our application and I have no other use for it. I am very disappointed.



by:

Poor quality trailer light connector/transmitter. I received two different ones both with already broken transmitters. The first one was the wrong part anyway.

Oh my goodness! I will have our Customer Service team reach out to you so that it can be replaced.



by:

Light works good very easy to set up and use. I do wish the battery life was better. The first battery died after 2 months. Called Custer and they immideatly sent me a new battery within a few days. The battery was easy to exchange and only took about 5 Min. The new battery has been good for the last 11 months.The batttery will need to be recharged after about 6 hours of use.



by:

I use the light bar to pull my car behind the motorhome. Light bar kept me from cutting the wiring in my new car. Works great

Great in concept, but seriously lacks in performance. This light broke and stopped working 1 month into use.

This light has a three year warranty. Can you tell me more about how it broke? Do you still have the light? I can send you the warranty details if you would like.



by:

Haven't had time to really use it, but I connected it and all lights appear to be working as designed. This saved me a lot of time. Rather than having to run wiring through my truck and modify the taillights, this will do just fine! Hope it holds up and glad it's made in the USA.

Love it! No hassle, no fuss. Only issue I had was forgetting to recharge life of the battery isnt all that long but we dont RV much at night. My truck bed didnt have a cigarette lighter that was hot with the key off. I ran a hot lighter to the bed and problem solved. This unit beat the extensive wiring that necessary to make my truck lights work off the RV Class A.



by:

The internal battery is very limited. It is difficult to ascertain when it is on and when the battery dies. It seems to have almost no life and when it goes out while driving you don’t know and are going without signal in a crowded freeway (voice of experience). We run a charge cable to the unit to keep it alive. We also add to modify the unit so that we could run the charge cable because of the location of the jeeps antenna. Would not buy again.



by:

Works well



by:

The ease of set up and use is just fabulous. The only drawback for me is the battery life. We have used this on several trips and only get about 7-8 hours of use before needing a charge. So, if you are planning a long day of driving, plan to charge during a stop or 2.



by:

The instructions and accompanying videos on your site made this a DIY installation that came out perfectly.

1. My radio antenna is in the way (2021 Cherokee). I have to place the unit in front of the antenna so the magnets cover the roof steel 100%. I remove the whip so the center light can barely be seen. Can I do that?
2. No directions came with it. How do you replace the battery?
3. Should have come with a charger I can plug into the wall. Do you sell one?

I reached out to the manufacturer about the question on the placement of the light and they will reach out to you to discuss it. I recommend viewing the video that we have on the light for information on installation. The rechargeable battery charges with the included 12V DC accessory socket.

My 2021 Jeep Grand Cherokee L didn’t have the wiring harness available yet at the time I had the front hitch installed so I opted for the Custer wireless LED tow bar light. It has performed well during our 3800 miles trip this summer. No problem encountered.

Im using this unit on my truck/camper towing my 2022 ford bronco. first problem i had was NO METAL on the bronco..lol I had to fabricate a metal bracket to mount on top of the spare tire. once that was complete the unit works great. the stop light feature flashes under braking, which is really nice as it really gets trailing traffics attention. magnets are super strong. easy installation (if you have something steel to sit it on)..



by:

works great, strong rubber coated magnets hold tight, could not be an easier way to install lights on tow vehicle.

A few glitches ,but nothing a handyman couldnt handle, 1 nut that holds the handle on vibrated off and was rattling around inside the unit, had to disassemble the light to replace. The charger connection plug became a loose fit causing intermittent charging while traveling, distorted the male plug to an oval to keep connection tight.



by:
2021 Chevrolet TrailBlazer

Simple install. Works great. Eliminates a lot of wire splicing that can only lead to problems. I would highly recommend this Tow Bar Light as opposed to running wires to the tail lights.



by:

still charging it up and will try it this week.looks good



by:

I’ve used the Custer light bar for about 8000 miles and it’s been perfect. Great battery life although I only drive during day. It fits perfect on my 2022 Spark and I didn’t need to cut the wiring.



by:

Seems to work well easyest installation



by:

Have not used the product yet but the overall quality is excellent and will make my flat towing much easier

Lite bar won't charge...went to use it and the batt was dead. Had to use the cord which was very inconvenient

A product this expensive should just work - especially when brand new

I have heard that the connection of the charging cord can loosen up over time. When you go to charge the light make sure the cord has a tight connection. Please let me know if that helps.

Looks great.. Just charged it and tried it. Looking forward to trying it on an actual trip over Labor day.. Great to not have to mess around with wires and all...

  • 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...

  • Can The Custer Light Bar Transmitter Be Placed In The Towed Vehicle 7-Way
    No, the Custer Wireless LED Tow Bar Light # LIW-LDTL-7B would have to be in the motorhome 7-way in order to receive the traffic signals from the motorhome and send them to the light bar. If it was in the towed vehicle you wouldn't get a signal at all since the vehicle isn't running and sending anything to the 7-way. The Blue Ox Patriot # BLU37TR would get its power from the battery of the towed vehicle. In most vehicles the 12v outlet loses power when the vehicle isn't running so you would...

    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.

  • Custer Wireless LED Tow Bar Light Will Not Power On When Switch Is Activated
    Hey Luther, sorry to hear about the problem you are having with your magnetic tow light. If you are sure it is fully charged and it will not power on, it could be due to a bad switch, or something else has failed internally. Sadly there are really no troubleshooting steps or replaceable parts for this so if yours will not power on it will be time for a new one.
