Bright lights with a long burn time
I'm doing a long ride in a few weeks time, and quite a bit of it will be in the dead of night in the middle of Wales. As such I'm looking for a front light system which has a good 8hrs of burn time (I'll be stopping for a lie-down from time to time!) and a rear light which will be sufficiently bright to ensure country lanes (especially the corners) are well lit behind me. I've done the usual google searches but come up with very little for less than a gazillion pounds, given that this is not the norm for me, I'd rather avoid the re-mortgaging the house option! Any thoughts?
