Tow Lights are necessary to alert motorists behind the tow truck of changes in driving behavior when towing a disabled vehicle. Whether it be stopping or turning, the lights mounted on the tow truck are often obstructed from the view to the other vehicles behind the tow truck in traffic thereby creating a need to mount indicator lighting on the towed vehicle. There are several different options available to the towing industry and each definitely have their pros and cons. While it may be perceived that it is more time consuming and troublesome to use the wired version of the tow lights, they are dependable and do not require the charging needs of their wireless counterparts. The benefit of the wireless tow light is not only it's easy to use functionality, but also the extended length at which you can use the lights that a wired set of tow lights would be limited due to the length of the wire. It has been an idea of law enforcement that wireless tow lights lose charge and tow operators are not always steadfast in keeping them charged which presents a hazard to other motorists due to lack of indicators such as stopping and turning. Check with local and state laws regarding the requirements of tow lights. One major thing to consider when using any tow light configuration is that the contact they make to the painted surfaces of the towed vehicle could cause scratches, so some sort of rubber padding on the magnets or attaching surface should be used.
