I don't think there is a hiden meaning behind the Red/Blue lights. They used to be all blue but found that the red was easier to see during the day. Probably spent tens of thousands of dollars for a scientist type to do an encyclopaedia size report telling them what they could see with their own eyes.
Toggy,
Good to see another Goulburn Valley resident on the board. Does the saying, "Five litre, five speed, life is complete" mean anything to you? Or did I get your handle wrong?
