Nicking a generator from roadworks and towing it in does seem a little overkill, thought it might sort my fitness…
Obviously riding with my lights on is the most straightforward and simple solution, but where’s the fun with that? Besides, the idea would be to make it possible to have several riders going at the same time. Lots of headlights might be a bit painful on the retinas.
I reckon rope led’s are the way forward;
Blue on the outside of berms, green on the inside, yellow at the lip of jumps, orange on drops and red for gaps… (not entirely serious suggestion)
