Mike.
Having looked at the pictures of the vehicle in your link I agree that it would appear not to comply. The orange lights don't appear to be visible through 360 degrees, and, more importantly, they look like strobes. The usual way aerodrome authorities get around this problem is by escorting individual vehicles with a correctly lit airport vehicle. A good example would be when local authority fire vehicles attend an emergency and are escorted to rendezvous points airside. I presume that the St Johns vehicles wouldn't be for regular airside use so it would not be practical to equip them to a CAP168 specification. As has been stated, nobody really polices this sort of thing seriously and aerodrome authorities seem to only notice vehicle lights if they're not on! Usually after ATC prompting. Having said that however, the use of powerful strobes on a vehicle on the apron, particularly at night, would be very unadvisable for various reasons. Probably not much help but I mean well!!!

P.S. I've seen too many people helped by the St.Johns to EVER take the p***
Oh! Forgot to put in........
As a St.Johns driver would be exceedingly unlikely to have a current airside driving licence an escort would be obligatory. (I\'m talking about attending at any \'regular\' airport).
