To ask the Minister of State, Department for Transport what research (a) his Department and (b) its agencies have undertaken on the effectiveness of (i) halogen and (ii) bi-xenon headlights. (318636)

The Department for Transport has commissioned two studies related to the effectiveness of halogen and bi-xenon headlights.

TRL carried out a review of existing research on gas discharge (i.e. bi-xenon) headlights in 1994 to assist in the development of European regulations on the subject.

In 2000, ICE ergonomics at Loughborough University studied headlight glare and driver vision to help establish a basis against which future headlamp performance requirements might be assessed.
