HC Deb 28 November 1989 vol 162 c181W
Mr. Roger King

To ask the Secretary of State for Transport if he will consider the safety aspects of forward-facing green-coloured roof marker lights displayed by trucks.

Mr. Atkins

I am not aware of any safety benefit, or harm, due to green roof-mounted lights on trucks.

The rules on lighting require that if additional lamps are fitted which serve to indicate the width as well as the presence of the vehicle, they must emit white light. These do not, however, prohibit the fitting of green ornamental lights near the centre of truck roofs.
