Benny,
I don't agree with your reason either BUT, I think there is a legitimate reason for having the lights on the roof.
A conventional light sits BELOW your eye height, so that your viewing angle of the road is greater then that of your lights.
What difference does that make?
Well, your lights will not be able to shine into potholes in a road. So you will see the pothole but it will appear black and you cannot judge it's depth. I am sure we've all experienced this off-road. A similar situation will happen when going over a crest of a
hill. You will see over the
hill, but your lights will not shine there.
With lights on the roof (ie, above your eye height), every hole that your eyes can see will be lit up and cleary seen.
But there is a draw back, and I am guessing that this is precicely the reason why roof lights have been illegal for so long (until 1st July 2007).
When on a road going over the crest of a
hill, your roof lights will "dazzle" the driver in the oppostie direction long before you see their standard lights and realise that they're there. And according to the legislation, if your lights dazzle other drivers, you can be fined.
So if you can't use your roof lights on any road, the only reason to have them on the roof is for show (and when on private property.
From Transport Operations (Road Use Management—Road
Rules) Regulation 1999
219 Lights not to be used to dazzle other road users
A driver must not use, or allow to be used, any light fitted to
or in the driver’s vehicle to dazzle, or in a way that is likely to
dazzle, another road user.
