This one is Red. Auto Theft Deterrent LED Simulated Car Alarm + 2 window warning stickers. *Thieves look for easy targets with a low risk of getting caught. This flashing LED will make them think your car has an alarm system and GPS tracking device. They'll move on to an easier target. No wiring or patching into your car's electrical system. Powered by 2 AAA batteries. It has an on-off switch so you only need to activate it when needed. LED's use very little energy. If left on, the batteries will flash the LED for weeks. Turn it off when it is not needed to provide a credible warning for many months. The LED is attached to the battery pack with 12" of wire. The battery pack can be placed in your glove box, on the dash board, center console, ash tray or in some other cubby. Dangle the LED so that it is visible to anyone looking in from either side of the car. It is very bright at night and easily seen. Match your cars interior lighting system. Choose from Amber, Red, Blue, Green White, Blue/Red or Rainbow. The single color ones flash about once per second. Red/Blue alternates like a cop car flasher and Rainbow changes from red to blue to green with flash rates from slow to fast and back again. (It almost makes it look like an indicator light for a GPS system that is transmitting a signal up to the satellite) (Batteries are not included) Other Ideas: 4th of July "safe sparklers", party decorations. Put them in a cut glass vase and they light up the room, "psychedelic". Use in Halloween pumpkins, light up their eyes for a "smashing" effect. Christmas decorations? Retail store attention getters? To attach the warning stickers... *Make sure surface is clean. *Spray a liberal amount of water or water-based glass cleaner to the inside of the window. *Peel the protective film from the face of the sticker and apply the sticky side to the surface. *Smooth to remove water and/or excess air under the decal.
