A device for protecting leading surfaces of a lens of an emergency vehicle warning light. The device has a replaceable, transparent shield adapted to be conformed to the profile of the leading surface. The shield is attached to the lens by upper and lower grooves formed in the lens. Notches are provided to assist with removal of the shield for replacement. Channels are provided to drain moisture from the lower groove. A first lens modified protector provides tracks, secured to the lens, for securing and conforming the shield to the lens. A second modified protector provides a thin, removable film for attachment to the lens by a pressure sensitive adhesive. A third modified protector provides a heating element attached to the shield for thawing, and for operably defrosting and preventing accumulation of frozen water products from and on the shield.
