Doh! Sorry guys, please ignore my ignorance regarding LED and HIDs. For future reference I know very little regarding electronics.

Maybe you can tell me if you could hook up the Red/Blue grain of wheat bulbs behind the grille to the same electrical connections as the indicators. You could then put the hazard lights on and get red/blue alternating flashes - this would move the Vectra over so you could get past. Would be neat if the public thought the Police had an XF.
