12 LED Light Set. To suit 1/10 scale models car or truck shells. Lights react to receiver signals so for example if braking the rear red leds will show (depending on how you set it up). Total of 12 LEDs recommend using light buckets (not included). This set would be powered by the receiver (any 27mhz / 35mhz / / 40mhz AM/FM or 2.4ghz) which must be running by an esc or have a 6v DC input if using two servos for nitro models. Note: Servo and receiver pictured not included.
