Abstract
Abstract A shade 17 surrounding the lens 20 of a centered "high mount" vehicle stoplight has an extension 17aat its upper end which blocks light diffused/dispersed by the lens and reflected inwardly by the rear window 1 to prevent such light from reaching the driver's eyes via the rearview mirror. The extension is sufficiently long to block light running substantially parallel to the lens and striking the window at a maximum angle Θ, whereby it will inherently also block the remaining light striking the window at a smaller angle.
