              1. Scope

              1.1. This Regulation applies to:

              1.1.1. PART I: Approval of audible warning device, audible warning system, multiple audible warning system supplied with direct or alternating current or compressed air, which are intended for fitting to motor vehicles of categories L3 to L5, M and N, excluding mopeds (categories L1 and L2);[1]

1.1.2. PART II: Approval of motor vehicles listed in 1.1.1. with regard to fitting of devices specified under Part I.

              I. Part I. Audible warning device, audible warning system, multiple audible warning system
              2. Definitions
 For the purpose of this Regulation:

2.1. "Audible warning device" means a device consisting of one or several sound emission outlets that are excited simultaneously, emitting an acoustic signal which is intended to give audible warning of the presence of a vehicle in a dangerous road traffic situation and which is intentionally operated by a driver;

2.2. "Audible warning system" means a combination of audible warning devices mounted on a common bracket operating simultaneously by the actuation of a single control;

2.3.  "Multiple audible warning system" means a combination of audible warning devices capable of functioning independently;

2.4. Principles of operation of audible warning device, audible warning system, multiple audible warning system:

2.4.1. "Pneumatic" means a principle of operation by an external compressed air source;

              2.4.2. "Electro-pneumatic" means a principle of operation by a compressed air source which is controlled by electrical supply (direct or alternating current);

              2.4.3. "Electro-magnetic with resonator disc" means a principle of operation by electro-magnetic force amplified by resonator disc;

2.4.4. "Electro-magnetic with horn" means a principle of operation by electro-magnetic force amplified by a horn;

2.5. "Type of audible warning device (audible warning system, multiple audible
