Thank you for viewing. This is a VARAD EVO SCANNERS LED security scanner. I've forgotten the part number. It has a silver body with 7 LEDs. The LED colors are red, blue, and purple. You can switch patterns and colors by pressing the chrome button in the center. The wiring has four wires: constant power, ACC, ground, and trigger. I used it in combination with an aftermarket security system (DEI Viper). It was fully functional, but I purchased it 21 years ago and removed it from the vehicle 15 years ago, I believe. Operation has not been confirmed. I think it's a rare item now.
