5.5. A headlamp may consist of a single reflector with a dual filament bulb, or separate reflectors each with single filament bulbs providing the functions of main beam and dipped beam separately. This will be considered as equivalent to a single dual filament headlamp unit. Lamp units comprising two reflectors where one is fitted with a dual filament bulb will be considered as a combined headlamp and auxiliary lamp. In this instance therefore no additional auxiliary lamps may be fitted.
5.6. Auxiliary lamps unless fitted as standard equipment using gas discharge or LED technology are not permitted and gas discharge or LED headlamp units may not be retro fitted.
5.7. Auxiliary lights must not be used in neutral sections except in poor visibility as permitted by law.
5.8. Where more than four beams are fitted as standard, only four may be used and the remainder must be rendered unusable for the duration of the Event.
5.9. Vehicles must have all lights fitted and used according to motor Vehicle lighting regulations. 5.10. External navigational or Marshal lights are not permitted.
5.11. For Events taking place wholly between half an hour before sunrise and half an hour after sunset App. 15 Art. 2.3, Art. 5.1, Art. 5.2 and Art. 5.10 do not apply. App. 15 Art. 6.1 is relaxed to permit advertising not exceeding 1250 sq cm in total. Also, it is permitted to fit a sunstrip of no more than 90mm deep which may display the manufacturer’ s make or model, or the name of the Event, or a recognised Motor Club, or a registered national charity, provided that this does not affect the Driver’ s view.
