Advanced equipment: Headtorch!

My friend Lindsey, who is a recent back to knitting convert – after many years in the wilderness, told me she used her headtorch for knitting at night on the motororways. I tried it and it is genius. It has made it possible for those long stretches of endless straight road to be pure knitting indulgence. Thanks Linds X

Does anyone have any other canny tips to enable 24/7 knitting? Or can comment as to whether the above means we are now road traffic criminals. (I need to stress that the beam is low and lies directly on the stitches!)
