Sr-Q Srs Pro Diffused Mid/Surface Mount. It’s all about stealth with RIGID’s new Midnight Diffused Lens. Available in SR-Q, SR-M and D-Series, these lights feature blacked out hardware, blacked out spot optics and our NEW blacked out Diffused Lens. The Midnight Optics along with the new smoked diffused lens enable RIGID to virtually disappear during the day while still providing powerful LED technology to light up the night. Thanks to improved LED technology, the Midnight Edition PRO now gives more light output than ever before.
