the existing stop-lamp switch and circuit are capable of taking the extra load.

5.2.18. Additional requirements for electric vehicles:

         5.2.18.1. Electric vehicles fitted with an electric regenerative braking system of category A;

         5.2.18.1.1. the electric regenerative braking shall only be activated by the accelerator control and/ or the gear neutral position.

         5.2.18.2. Electric vehicles fitted with an electric regenerative braking system of category B;

         5.2.18.2.1. it must not be possible to disconnect partially or totally one part of the service braking system other than by an automatic device;

5.2.18.2.2. the service braking system must have only one control device;

         5.2.18.2.3. the service braking system must not be adversely affected by the disengagement of the motor(s) or by the gear ratio used;

         5.2.18.2.4. if the operation of the electric component of braking is ensured by a relation established between information coming from the control of the service brake and the braking force to the wheels which of it results, a failure of this relation leading to the non-respect of the prescriptions of distributor of braking among the axles (annex 5 or 6, which is applicable) must be warned to the driver by an optical warning signal at the latest when the control is actuated and having to remain lit as long as this defect exists and that the switch of "contact" is in the position "go".

         5.2.18.3. For electric vehicles fitted with an electric regenerative braking system  of both categories, all the relevant prescriptions shall apply except paragraph 5.2.18.1.1. above. In this case, the electric regenerative braking may be actuated by the accelerator control and/or the gear neutral position. Additionally, the action on the service braking control must not reduce the above braking effect generated by the release of the accelerator control;

         5.2.18.4. The operation of the electric braking must not be adversely affected by magnetic or electric fields;

         5.2.18.5. For vehicles equipped with an anti-lock device, the anti-lock device must control the electric braking system.

         5.2.19. Special additional requirements for the electric transmission of the parking braking system:

         5.2.19.1. In the case of a failure within the electric transmission, any unintended actuation of the parking braking system shall be prevented;

         5.2.19.2. In the case of a break in the wiring within the electric control transmission, it shall remain possible to apply the parking braking system from the driver's seat and achieve the parking braking performance specified in paragraph 2.3.1. of annex 3 to this Regulation. It shall also be possible to release the parking braking. system, if necessary by the use of an auxiliary release device carried/fitted on the vehicle. The engine/manual transmission or the automatic transmission (park position) may be used to achieve the above performance;

         5.2.19.2.1. A break
