bright flouro clothing is USELESS for nighttime visibility - reflective or it doesn't count -

i ride in sub/urban areas so my concern is being seen - there's enough ambient light for me to see where i'm going. i've got reflective sidewall tires, ankle straps and a construction vest. in front i've got a PB blaze 2w and a small
yellow blinky. on the rear i've got a radbot-1000 and a bspoke version of the PBSF. monkey-lectric on the front wheel.
rechargeable ni-mh batteries in everything.
during the day i've got my reflectives, radbot and blaze. at night i look like timothy leary's christmas tree.
if i needed light to see, not just be seen, i'd get one of these -
