Steve Martin, the lights on my grill is the Rough Country LED Grill Light Kit. They are designed to steady burn as an off road light. I work in an emergency vehicle equipment sales and install shop. I purchased a LED Flasher and wiring it thru a diode and relay setup built in our shop, I am able to make it flash for emergency response and also it will still steady burn as designed by Rough Country. It is white only. The flasher I used had some other patterns but for this application, I chose the simple alternating pattern.
