RIGID Rear Facing High / Low Dual Function LED Lights in Amber or Red provide the flexibility to adjust the lighting to the conditions with the flip of a switch. These lights feature a three-wire harness, and the High, Low, or Off three-position rocker switch gives the user an option to run at full intensity on high power, or 20 percent intensity on low power. Use the low intensity mode for a low powered running light and the high powered as a braking light.
