HotLinez LED Tailgate Bars are the hottest addition to any truck. This LED Light Bar features 60 LEDs that act as a Brake Light, Turn Signals, Running Lights, & Hazards. It works with your existing truck's signal system for simple installation by plugging it into your trailer-hitch adapter. If you do not have a trailer-hitch adapter, instructions are included to hard-wire it. 3M Self-Adhesive Pads mount the LED Brake Light below your tailgate so the bar itself is not visible, only the light emitting from it.HotLinez can also be mounted on the side of your truck as running lights/turn signals.  If you wish to do this setup, you will need to order 2 bars.
