Im assuming your talking about the UK law of you must have a 'flasher' on your bike if your insistent on using a 'static'
Despite the weather I have never own a 'mac'

The Exposure guys have new rear lights too and they do a pack with an aussie plug. Im assuming they are for sale over here as Ive seen a guy at the track with a set on his bars.
I can personally recommend the 'joystick' for a front light for commuting(or second night helmet light) - great charge time, water proof, great running time two static settings and yes Yoni it does have a flasher mode

you may need the more powerful version for serious off roading at night.
Also bear in mind if your going off roading at night, the most powerful light is not necessarily the best as some can 'white out' terrain - go for quality of light over brute power (lumens)
Having worked and a bike shop for a few years and having had to educate the public on draconian UK traffic law towards bike lights I couldnt agree more on her stance on rear lights.
Ive been quite alarmed at seeing the amount of little backup lights being used as permanent lights on the back.
Be safe Be seen
