The Demco Wireless LED Light Bar is a great product! Road safety is always a concern for travelers who tow a vehicle behind their motorhome. Using the Demco Wireless LED Light Bar is a great way to increase visibility on the roadway. We find it useful to have the Demco Wireless LED Light Bar because we carry bikes on the back of tow vehicle that may cause slight visual disruption. The Demco Wireless LED Light Bar gives us piece of mind that our tow vehicle signals are clearly visible.


The Demco light bar is a great solution to the problem of dangling wires across your vehicle in order to put lights on your vehicle in tow. It is also a less expensive option than wiring the lights into your vehicles existing lights. It mounts nicely in the vehicle and stays in place well. The wire that powers it is plenty long enough to reach to the vehicle's lighter socket. You need to make sure, however, that the power stays on in your vehicle when it is tow. The transmitter requires a 7 pin round connector, and syncs up easily.


Concerned about the safety of towing your vehicle and looking for a product easy to use right of the box to help solve this issue? The Demco wireless light bar is definitely worthy of consideration. I was able to install this product completely within a matter of minutes after opening the box. The instructions were easy to understand. Installation in the rear window of my tow vehicle literally took less than 45 seconds. And the only "installation" required was plugging in the included 7-way plug that includes the wireless transmitter. The light bar quickly indicated turn signals, braking and emergency lights. It is a solid product with durability and appears that it will be long lasting. It's easy to remove when not towing and takes up minimal space when not in use. It is important to note that you will need an "always on" 12 volt supply to power the light bar or you'll need to spring for an opitional add on product to provide power to the light bar. This is an excellent product and definitely something that helps me know that my tow vehicle braking and lighting is visible to other drivers and the fact that it doesn't require string wires from my RV to the back of my two is worth a lot!


Extremely easy to use! Plug and play does not oversimplify it. We bought an adapter for the 7-blade to 6-round for our specific setup and we were set. The cord from the light to the power source inside the vehicle was plenty long enough and once everything was plugged in it starts working immediately. No pairing/no setup. The articulation with the ball joints allows you to set the light bar to just about any angle you might need, and it holds firm with no movement during travel. We have a Class C and are pulling a Jeep and see no issues with signal strength from the adapter in the RV to the light bar. We really like the added security of having the extra lights to let those behind us know what we are doing.


I do highly recommend this product for the ease of installation and the functionality of it. This unit is very bright and visible from afar. It definitely gives us the extra comfort and security that we were needing while towing our vehicle.
