I thank Deputy Ahern for raising this question. Ministers of State, Deputies Canney and Buttimer, and I had good discussions on this with officials yesterday in preparation for questions here. This issue of the new LED lights and high intensity discharge, HID, headlights are known to provide greater brightness, improved colour rendering, increase efficiency and, in the case of LED in particular, longer performance life. That is fine and that is good. However, I am aware of the concerns and the Minister of State, Deputy Canney, and I have discussed the concern expressed in some quarters in relation to glare particularly with LED and HID headlights. The Deputy might note that the use of these headlights in the EU is regulated by the European type-approval system. This system establishes the technical and safety standards required for a vehicle or component of a vehicle to be placed on the European market and to place a vehicle or a vehicle component on the market and used within any member state. Type-approval requires the vehicle or component to meet specific safety requirements. Accordingly,if a headlight has been approved and entered into service, it is considered safe to use within the EU. During roadworthiness testing, the lighting system in a vehicle is tested to ensure it is in full working order and, importantly, correctly aligned for the safe performance of the vehicle. Factors which can contribute headlamp glare include misaligned aim and various other things. I understand that the UNECE Working Party on Lighting and Light-Signalling is going to establish a task force to investigate this issue and I can assure Deputy Ahern that I, Minister of State, Deputy Canney, and my Department will be guided by that work.
On a personal level, I have experienced this as well. I do think this is a matter which needs to be looked at. It is a European competence in relation to the specifications. However, the survey clearly shows that four in five motorists have experienced this. All of us have at this stage. It does merit further investigation. That working group will be important and we will be guided by its recommendations.
