The reflectors I bought from sjscycles.co.uk arrived today, 2x
Cateye front reflectors (only ordered one bracketed but both arrived bracketed) so I had a spare in case I screwed one up, and a
Cateye back reflector which I only threw into the order because it was cheap and might have been good on my bike except for the mounting block on the back sticks out quite far and the setup I have for the back light/reflector (shown in the first post of this thread) is much thinner.
I managed to steal 15 mins on a milling/drilling machine today so:
Merv, the LEDs won't be directly powered from the bike battery's voltage but through a 5v regulator, then the LEDs will be powered in parallel sets of 3 with a current limiting resistor. The regulator will have a fuse between it and the bike battery so it'll blow if anything shorts, a rough estimate showed I'll need probably 1.5A at 5v to power all the LEDs.
