Pulsating LED lights, had them on my Harley’s, would turn them on if oncoming left turn vehicle was approaching, many times oncoming cars,trucks etc. saw the lights and didn’t turn left in front of me, easy to install. I hooked them up to my high beam switch. These lights save lives…. They all have various pulsating patterns and different colors. These hook up to switch and only come on when rider needs them on….
