Darin, in Ontario its the same thing about lights, if you can see signals on the car (turn/stop) during the day (1/2hour after sunrise and 1/2 hour before sunset) then you need nothing as per Part VI Section 62 Subsection 24 , the cop probably didn't know what part of the trafic act to look under:dunno:
"""""""""""""""""""""""""
Lamps required on rear of trailer, etc.
(24) When on a highway at any time from one-half hour before sunset to one-half hour after sunrise and at any other time when, due to insufficient light or unfavourable atmospheric conditions, persons and vehicles on the highway are not clearly discernible at a distance of 150 metres or less, every trailer and every object or contrivance drawn by a vehicle shall carry on the rear thereof one lighted lamp, which shall display a red light only. R.S.O. 1990, c. H.8, s. 62 (24).
