Rigid Industries police, fire, first responder, military, and EMS LED lights have an advantage over strobe and rotating light bars by being extremely durable and having extended lifespans. Traditional light bars often have lights with filaments in them that can burn out or shake loose over time. LED light bars do not have these problems. The lifespan is three times greater than traditional lights. Additionally, our lights have 100% On/Off performance with no warm-up time.
