I just checked the Highway traffic act ...
Note:
If a Police Officer or Ministry Officer believes that your vehicle is not "in compliance" he/she can give you a notice to take it in for testing within 96 hours to the ministry testing facility designated on the notice. If the officer believes it is dangerous, they can take your plates right there and then on the roadside and keep them until your vehicle is proved to be safe and/or repaired. It's a lot of hassles for them and a lot of paperwork. If you're nice and polite to them they will probably just give you a warning.
Here's some sections of the traffic act:
62.(1) Lamps required on all motor vehicles except motorcycles
When it’s dark or difficult to see, your vehicle must have 2 headlights on the front 1 white or amber side marker on each side and one red taillight (yes only one).
62.(4)Light requirement
Your lights have to be bright enough to be clearly seen from 150 metres.
62.(6) Strength of lamps
Your headlights must be bright enough so you can clearly see anybody or anything within 110 metres head of you.
62.(9) Strength of front lamps
You can’t have more than four lights on the front of your vehicle that are brighter than 300 candela.
