The Exposure Lights Lighting Guide


  1. Length of time in darkness - Sunset on the 7th is at 21:07 and sunrise is at 05:19 on the 8th. 8 hours darkness for the 24 riders, 3 hours for the 12 riders. Depending on at which point you choose to turn your lights on.
  2. Availability of access to pits/length of lap - Lap times will be around 1hr 10min for the leaders. (Exposure Lights are offering a charging facility for those that have sets of lights to swap and charge. We charge all lights but only have chargers for our lights.)
  3. What lights you have available - Take stock of the lights you have and assess whether they will see you through the darkness at an output that enables you to maintain your preferred speed. (Exposure Lights are offering a hire program to take care of your lighting needs and proceeds go back into running the event. For more information email

Recommendations and Preparations:

Preparation - Charge your lights fully before the event! Thorough preparation will ensure that you not only have the tools to do the job but you'll be able to prepare better mentally for the task ahead. Test the lights on a night ride prior to the event so you are sure that they work as you are expecting and that they have the run time that you're preparing for. If you are new to night riding test your skills in the dark. Use your well known trails so you don't get lost or suffer any surprises. The trails will seem a completely different place in the dead of night and it'll inspire you to get out more for fun in the dark.

Set-up - Light set-up is a personal thing, we recommend that you position your light giving the maximum penetration into the trail ahead. For Handle bar mounted lights start be setting the bike up on level ground and then attaching the light so it is pointing slightly below horizontal. This allows maximum warning of oncoming obstacles which will keep you looking ahead for safe, fast riding. Having the light pointing too low will just dazzle when reflecting off the ground. Keep the light as close to the stem as possible, it keeps the beam pointing in the best direction and it will eliminate the tiny effect of misbalancing the bars. For helmet mounted lights align the light so that it naturally points where you are looking. If the light points off at a strange angle then you will constantly have a twisted neck as you adjust for the inaccuracy. To do this, stand away from a wall and focus on one point while looking straight ahead. Turn on the light and make sure the beam meets at the same point on the wall.

Using Exposure Lights - 24 Hour riders. If you have one set of lights you can use the 10 hour setting then you know that when you have switched them on that they will run for the whole night. If you want to make use of the higher 3 hour setting for bursts of speed in safety you will have to turn the lights to the 24 hour setting on the slower parts of the course to preserve battery. Piggy Back batteries can also be hired to extend the burntimes of the lights if you want to maximise your speed at night. If you have more than one set of lights work out the combination of use against the burntimes of the lights that can be found on the bottom of the light. For 12 Hour riders the lights can be used on their 3 hour setting so keep them on their highest power and head for the finish.

Lights to look at - 24 Hour, MaXx-D / Six Pack are the lights to aim at for 10 hour brightness as they will provide what you want for racing. Couple this with a helmet light for a more directional light that will help you in the twisty sections of the course. For more information on these lights visit or refer to the light hire form. If you're racing in the 12 hour you can use either of the lights mentioned above or the Toro would be great for this purpose. For either event, if you prefer more helmet mounted light then consider the Diablo with Piggy back cells to extend the burntime.


Remember, generally the more light the better. It means speed and safety. Then you can really enjoy the night hours. Your pit crew might like a little lighting too so their lives run smoothly. If you have a spare light pack that with you as you will be prepared for problems or there to help a stranded sole on the race track if needed. They might even be carrying that chain tool that you need later on the lap. Enjoy training as the event nears and keep well lit for safety whenever you're riding in the dark.
