Research into the effectiveness of daytime conspicuity lights on vehicles has been conducted for the Department by the Transport Research Laboratory. This work indicated that conspicuity lights could be of benefit in certain weather conditions, however, in clear weather, no obvious safety benefits were apparent.
The European Commission is presently considering the possible costs and benefits of the use of vehicle lights during daylight hours. The negative environmental impact of the use of vehicle lights in daytime is being considered as part of this work. No formal proposals to regulate in this area have yet been put forward but the UK continues to play its part in discussions with the European Commission and other member states.
