Exposure Lights Sirius Mk10 Daybright Front Light

With an increased output to 900 watts, the Exposure Lights Sirius Mk10 Daybright Front Light has gone from being a favourite 'to be seen' light to a 'to see' option, making it ideal for darker country lanes. Constructed from CNC machined aluminium and with an IP65 water rating, this light is tough, durable, and reliable in all conditions. Visibility extends to the sides, with 240° illumination making sure vehicles approaching from the front and from an angle are fully aware of your presence. 

There are a number of modes to choose from, both static and flashing, including DayBright, a pulse that cuts through distractions in the brightest sunlight. Intelligent Thermal Management prevents the light from overheating by reducing power to the LEDs when they go over the optimum temperature. Once cool again, the output will return to previous levels. 

The light has a 7-hour battery charge time and a maximum run time of 36 hours, depending on the mode selected, and there's a fuel gauge to alert you to the remaining battery level so you don't get caught out.
