**The new “SUPER-LUMEN” patches will outshine your existing GITD patches, and glow for up to 8* HOURS in the dark!** Vanquest’s “SUPER-LUMEN” Glow-In-The-Dark patches will outshine any of your GITD patches, and glow for HOURS in darkness! Our R&D has finally perfected the “SUPER-LUMEN” formula: It is super bright, easily charged, and can glow for up to 8* hours in the dark! These “MED” Medical patches are perfect for identifying your medical gear, day and night. *Please let your eyes adjust to the darkness, and use your light-sensitive peripheral vision to observe the glow as the “rod” photoreceptor cells on the peripheral part of your retina are more light-sensitive than the “cone” cells at the center of your eyes.
