Feb 7, 2019 at 10:22 comment added Criggie @JamesBradbury yep - that's the sad state of affairs in some countries.
Feb 7, 2019 at 8:24 comment added James Bradbury Although in most places the chances of police stopping cyclists for incorrect lighting are small, in the event of an accident drivers may use the SMIDSY defence to avoid taking full responsibility if you were missing a pedal reflector.
Feb 6, 2019 at 15:19 comment added Baldrickk If it's a "warm white" yellow, then that should be fine (I'm specifically thinking of old incandescent bulbs here, or LEDs that emit a warm light). Likewise, a "cool white" light (majority of LEDs) isn't blue. If it can be more accurately described as "amber" (colour designation here) then don't use it unless it actually is an indicator light (though I don't find that the ones you can get for bikes are much good)
Feb 6, 2019 at 9:49 comment added Criggie @gerrit that's what the rules say. White is front, red is rear. A yellow might be seen as an indicator or a running light, specially in fog or poor conditions. Oh, and yellow used to be a stationary light fitted to roadworks so yellow could also be seen as a stationary obstruction (though those have been phased out now.)
Feb 6, 2019 at 8:12 comment added gerrit Must it really be white? Yellow is not allowed?
Feb 5, 2019 at 21:11 comment added Criggie @mark goes to show one shouldn't rely on memory. All fixed.

Went and looked up the authoritative source. Even living here for decades I still made a couple minor mistakes. Fixed.
Feb 5, 2019 at 21:05 comment added Criggie @mark nzta.govt.nz/resources/roadcode/cyclist-code/about-equipment/… has the proper list - updating answer now.
Feb 5, 2019 at 21:03 comment added Mark Is that rear reflector size "175 square millimeters" or "175 millimeters square"? There's a huge difference: 175 square millimeters is a tiny spot that I doubt I'd be able to see in time to avoid hitting you, while 175 millimeters square is a huge reflective patch that I'd be able to see well in advance -- and probably before I'd be able to see your rear light.
Feb 5, 2019 at 14:38 comment added ChrisW Yes in some jurisdictions a blue light is not only not-legal (i.e. is not the light which you're required to have), but it's also illegal (i.e. is impersonating a police vehicle).
