The STL201XRFHXB has a patent-pending circuit board configuration and LED light projection technology designed to create an optical bridge that projects red LED light from the red area of the lens to the clear area of the lens during the braking function; the same portion of the lens also is used for the white light backup function.
The lamps have lenses and housings made of a sonically welded polycarbonate material and employ a solid-state surface-mount design that helps protect their electronics against moisture, shock and vibration.
