What is a Good Wireless Towed Lighting System??

These are the Tow Mate wireless lights that I use. They work as advertised and Tow Mate stands behind their product. Had a set of old TN3N lights that the batteries were going bad. Since they no longer use that battery setup in their new lights they sent me a NEW set of lights for $50. I realize they are more than you want to pay but sometimes it's worth it in the long run.
