1.2. Except for Racing Cars be equipped with battery, generator, self-starter, side, tail, and brake lights. All this equipment to be in normal working order. Exceptionally when taking part in an event held totally off the Public Highway, need not comply with DfT Statutory Requirements regarding lighting or horn.

1.3. Have Auxiliary Batteries duly protected to exclude leakage of acid and to protect terminals from short circuiting and producing sparks.

1.4. If located in the Driver / Passenger compartment, where a Passenger / Co-Driver is present the Auxiliary battery must be situated to the rearwards of the base of the Driver ’s or Passenger / Co- Driver ’s seat and ‘wet’ batteries must be enclosed in a securely located leak-proof container.

1.5. Have the Auxiliary Battery earth lead, if not readily distinguishable, identified by a yellow marking.

1.6. If non lead acid Auxiliary Batteries are used as the main Vehicle battery, they battery pack(s) must carry the appropriate “EC” and markings and be either a Standard Part or manufactured by an ASN registered manufacturer.

1.7. Except for Electrified Vehicles , the total quantity of recuperated energy stored in the Vehicle must not exceed 200 kJ; this energy may be re-used without exceeding 10 kJ by means of 1kW maximum.

2. Starters

2.1. If required to have a self-starter, be able to demonstrate during the Competition that it is capable of starting the engine.

3. Radio suppression 3.1. Engines must be fitted with effective radio interference suppressors.

4. High Voltage (60V+)

4.1. With the exception of ignition systems any Vehicle incorporating an electrical system which may run at a voltage exceeding 60V must display the sign detailed in Drawing 1 of this Appendix next to all Competition Numbers.

Drawing 1

5. External Circuit Breaker

5.1. The circuit breaker, when operated, must isolate all electrical circuits with the exception of those that operate fire extinguishers.

Motorsport UK 2025 National Competition Rules Chapter 7 Appendix 5 - Electrical Systems 263

5.2. Any re-set of the circuit breaker must be operated by a distinct different action to the trigger.

5.3. The triggering system for the circuit breaker on saloons should be situated at the lower part of the windscreen mounting, preferably on the Driver ’s side or below the rear window.

5.4. On Open Cars the triggering system should be situated on the lower main hoop of the Roll-over Bar on the driver ’s side or at the lower part of the windscreen mounting (as above).

5.5. Alternatively on Vehicles of Periods A to F the mounting point may be mounted approximately vertically below the line of the scuttle on the Driver ’s side.

5.6. The triggering system location must be identified by a Red Spark on a White-edged Blue triangle (12cm base), with the ‘On’ and ‘Off ’ positions and method of triggering (Push, Pull, or a Rotation direction indicated by an arrow) clearly marked.

6. Red Warning Light

6.1. A rearward facing red warning light of a minimum of 21 watts, with surface area minimum 20cm2, maximum 40cm2, or of 21 watts with a surface area minimum of 50cm2 and with lens and reflector to EU Standards, must be located within 100mm of the centre line of the vehicle and be clearly visible from the rear.

6.2. Vehicles fitted with full width bodywork may alternatively use two lights equally located about the Vehicle centre line.

6.3. An alternative light unit of equal or enhanced constant luminosity or LED lights that are either homologated by the FIA or comply with relevant EU Regulations may be used.

6.4. The warning light must be switched on when visibility conditions are reduced, or as detailed within Championship and / or Event Regulations , or when so instructed by the Clerk of the Course .

6.5. Electrically operated Fire Extinguishers Refer to App. 6.
