4 Modes RC Flashing Light 12 LED Flashing Light System for RC Cars by RCRunning

Easy to install, lights are bright, not all my lights worked though. I emailed the customer service line so I will update if they get back to me. Update: customer service never got back with me. It's been over a year now. Lights are still bright but not all lights worked out of box. Also do not buy if you think turn signals will work. Left and right turn signals do not work. Just a generic flash setting.

Work very well
