Using red or blue strobes on your bike may get you into trouble. The wardens and cops have them, they may fine you for it. However.....the group of fellas you scare with them may cause you physical harm for making them toss their beers.
I am pretty sure that running flashing red or blue lights on any vehicle in Canada, unless part of emergency services is illegal.
I found this in the Nova Scotia Motor Vehicle act:
Red, blue or flashing lights
179 (1) No person shall drive or move on a highway a vehicle with a red light visible from directly in front of the vehicle unless the vehicle is
(a) an ambulance or school bus;
(
a police, fire department or fire patrol vehicle;
© a vehicle being used by the chief or deputy chief of a volunteer fire department when acting in an emergency arising from a fire or an accident; or
(d) a vehicle being used by a conservation officer appointed pursuant to an enactment when the conservation officer is performing duties as a conservation officer.
(1A) In this Section, "fire patrol vehicle" includes a fire suppression or fire vehicle operated by the Department of Natural Resources.
(2) In this Section, "red light" includes a red reflector or other device that gives or is capable of giving the effect of a red light.
(3) No person shall drive or move on a highway a vehicle with a blue light visible in any direction unless the vehicle is a police vehicle or a vehicle being used by a conservation officer appointed pursuant to an enactment when the conservation officer is performing duties as a conservation officer.
(4) In this Section, "blue light" includes a blue reflector or other device that gives or is capable of giving the effect of a blue light
I am sure it is the same all across Canada.
