No idea what the audio issue is about...uploaded it twice and same result...SORRY!
Here is a Motormax Ford Interceptor Utility / Explorer that has been painted (Thank you Sun Park!) and decaled as a WVSP unit. It has flashing headlights and tail lights added along with blue strobes in the grille and rear visor. Those are controlled by a circuit board that provides a couple of triple strobe patterns. There is a blue strobe lightbar on the roof and an interior worklight, too. Matching WVSP antennas were mounted...even the big ol' whip on the driver's fender! An Evan Designs 4-tone siren kit provides the sounds.
