Headlights have been a hot topic for Reliability Trials in the last couple of years, ‘what lights can be used?” and “how many can I run?” are some of the questions continually being raised as the 24 Hour Trial approaches every season.
The 24 Hour Trial and all other Reliability Trials incorporate the use of public roads as a part of the course riders must follow, and riders must still comply with the road rules when riding. Machines used in Reliability Trials and the 24 Hour Trial, must comply with the Road Traffic Act along with all other registered vehicles on the road, this means that a headlight must contain the high beam, and an effective short-range low beam behind the one lens. It must be a minimum of 25 watts and can only be fitted to the Motorcycle, (in the case of a sidecar).
Halogen, HID or or Light Emitting Diode (LED) with an (E) standard, which can be switched from high to low beam is acceptable. Lights that dim only, as a method of switching to low beam, or simply having a headlight pointing at a lower angle as low beam is not acceptable.
Where a combination of headlights are fitted (Maximum 2), Halogen, High-Intensity Discharge (HID) or LED with an (E) standard is acceptable for either headlight as the illumination. At least one headlight must contain the high beam, and an effective short-range low beam behind the one lens.
If two headlights are fitted and only one of the two headlights has the low beam, the second light is considered to be an auxiliary light, and therefore must be simultaneously switched off by means of the main headlight high/low-beam switch only, when lights are dipped to low-beam.
AUXILIARY LIGHT (second light) – NON (E) STANDARD Light Emitting Diode (LED) lights will be accepted only for the auxiliary driving second headlight. Only one auxiliary light is allowed along with the main light, and any amount of individual LED’s can be used in the LED array, as long as they are in the one housing.
Auxiliary driving light maybe isolated by a separate switch, but the high-beam or auxiliary driving light must not be operating when lights are switched to low-beam, and must be simultaneously switched off by means of the main headlight high/low-beam switch only, when lights are dipped to low-beam.
