I propose to take Questions Nos. 412 and 413 together.
The relevant regulations require lamps that show a light to the front of a vehicle to be fitted and constructed so that they will not dazzle or mislead other traffic when lit. In addition, such lamps must be fitted with a dipping device so that the beam of light from the lamp, when dipped, is incapable of dazzling a person more than 25 feet away from the lamp and in a specified position, which approximates to that of the driver of an oncoming vehicle. Exceptions to the dipping device requirement are made for direction indicators and for one or more other lamps with a combined maximum power output of seven watts. Dipped headlamps must be used when a vehicle is either passing another vehicle or travelling close behind one. The use of fog lamps is permitted only in fog or falling snow. Within this framework a maximum power rating is not specified for vehicle lights. The Garda has responsibility for enforcement of the regulations.
