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 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.
