4) Correct use of lights: Sidelights, or "parking lights" to give them their alternative name, are not to be used for driving. If it is suitably dim that you need any lights, use headlights. After all, lights are so others can see you more than so you can see others. And a dimly glowing parking light is no good to be seen.
Highway code doth proclaim:
You MUST
use headlights at night, except on restricted roads (those with street lights not more than 185 metres (600 feet) apart and which are generally subject to a speed limit of 30 mph)
use headlights when visibility is seriously reduced (see Rule 201).
ensure all sidelights and rear registration plate lights are lit at night.
Laws RVLR regs 24 & 25 & RV(R&L)R reg 19
So presumably as long as the drivers to which Adam refers are in streetlit, 30mph built up areas, then they are acting within the law??
