I'm thinking of getting myself an insanely bright rear light for commute use. Here in London you need to stand out...too many of the taxi drivers are blind.
I am thinking of perhaps one of these
but then modified by removing the bar mount from the base, adding a piece of angled bracketry that I can reattach the bar mount to, such that the light can then be mounted to the seat post, sticking out behind it.
to make it red, I thought Id get one of these
and swap the led pills over, giving me a white t6 torch, and a red luxeon k2 tail lamp.
Is it as easy as that or have I missed something?
Oh and I know the battery and charger with the head/tail lamp will probably be poo. I'll sort out decent 16850 cells myself, and use the charger I have already.
