Multi-Mode Light Bar: Not just a light bar with accent lighting, the XKGlow Razor light bars offer an optional strobe function to help bring safety and security where you're working. Flip the switch, and you'll get proper performance to see what you're doing too! From XKGlow: Want to enhance your driving high beam and fog light while driving, and increase safety with strobe light while working? This light achieves them all! The middle section is built with 80w 4800lm high beam and the two sides are equiped with fog+strobe LEDs. Flip the light from strobe to fog mode with the ease of one click. The control panel provides three strobe modes (check the video in the listing) selected by quick switching the STROBE button. The last running mode is automatically saved as default. Compared to common "round spot" beam, the 2nd gen Razor Series is design to meet the SAE J581 auxiliary high beam and SAE J583 standard for on-road fog light use (when installed as a pair and aimed in accordance with your state's regulations). The light beam is projected in a wide rectangular pattern with focus in the center, utilizing the automotive grade led light in the most efficient way for both on-road and off-road use. ** The included wiring harness has two outputs and you can select from "Make it a pair" menu to purchase one more light.
