When in the pre 20 second test mode a LEO's light bar will set the Blinder into alert. After test mode, the light bar had no effect.
Used my Blinder equipped truck & drove towards a "test vehicle" with a blue/red Whelen strobe edge light bar & LED red/blue grill inserts. Blinder went crazy with alarms in test mode. Would not reset alert. Just kept alerting. Made another pass all the way to point blank after test mode & no alert.
