4 Inch Round Shape LED Car Stickers, Wireless Decal Accessories Removable Glowing Sign for Car Taxi

People in the maket always call them "LED car stickers,  LED panel kit,  LED power decals, LED backlight logo, LED illuminated signs, LED car signs..."
 
Each LED car stickers is a super bright LED backlit logo that sticks on to the inside of your vehicle's window (no tools required). The battery operated device automatically turns on while the car is in motion and it's dark out. When the sensors detect no motion for 2 minutes or that it's light out, the sign light shuts off. Just set it and forget it.
An indicator light on the inside tells you if it's on or not. Because it's a bright light, you can see it through tinted windows too.
 
Each "decal" consists of a 4-inch circular graphic image, and a rear housing that provides backlighting via an LED light. The housing also contains light and motion detectors, so that once the power switch is flipped on, the light will only come on in the dark, and only when the vehicle is moving - once the vehicle has stopped moving for at least two minutes, the light automatically shuts off.
The device mounts on the glass via two adhesive-backed clips. It can slide in and out of them, should you wish to alternate between displaying different LED logo sign in the same location.
