Think we could persuade them to make a run of St. Louis Game Time branded lights like this? Powerdecal shines new light on car window stickers Perhaps there's a law of marketing that states, "If you want to add to an existing product's gee-whiz factor, just alter that product so it lights up in the dark." Really, who wouldn't want glowing paper clips, or baby bottles, or ... automotive window decals? That's the theory behind Powerdecal, a device that mounts on the inside of your vehicle's window glass, then displays an illuminated image of your favorite sports team, university, or other group to which you wish to proclaim your unflagging devotion. You might start seeing these on vehicles around town soon. St Louis Blues POWERDECAL POWERDECAL™ is an LED backlit logo for your vehicle window. Device turns on automatically while driving at night via sensor technology; device shuts off after 2 minutes once parked. Easy installation with quality 3M adhesion material, just peel and stick, no tools required. Actual Size: 4" LIGHTED DIAMETER Includes: Batteries & Window Clips (2 sets) Packaging: Quality white box; makes a nice gift.
