Why did they make such a fuss about not having the blue sidelights - does that mean they are allowed to be used then?
Aido,
This 'not allowed blue sidelights' has become such an urban myth and legend that even some police officers believe it. Its just a lack of knowledge as opposed to any maliciousness.
When you think about it, Xenon lights have a blue effect. But these arent illegal.
You will notice that some HGV drivers will have small 'xmas' trees on their dashboard. This is perfectly legal, (as long as it doesnt affect his vision ahead), nor have any red bulbs in it! Remember - no RED to the front, no WHITE to the rear. You get the idea..........
In terms of the HID discussion, watch that ANY light you install does not dazzle oncoming drivers. This could constitute 'dangerous driving', due to the condition of the vehicle. It is not the colour that is the problem, unless of course it doesnt actually give you any light ahead!
