This is a replacement left or right Vertical Outrigger Wireless Tow Light with Strobe. You should only buy this item if you have lost one of your two previously purchased outrigger tow lights, or if you only require a single light. (for example if you just want to use it as a single four way flasher or a single brake light).
Includes a single tow light with LED light, bracket and receiver. It can be either the left or right, and you can change it as required.
This does not come with a transmitter or a charger.
A complete set with charger and transmitter can be found here:
