1980s MTO Bilevel Lighting System The section of the 401 through Oshawa has a unique lighting setup, there are two cobraheads on each side of the pole. I believe this was a test install by the MTO to test a bilevel lighting system where the second light is shut off when traffic volumes decrease to save energy. I believe the original lumes used on this stretch are 100-150w HPS Powerlite R37s some of which has since been replaced by other lumes with the same wattage. Fun Fact: That GE M-400A3 is 100w HPS.

Hmm. Pretty interesting that they did that. It must not have caught on though...

Yeah since the MTO later switched to using highmast lights instead of cobras all together.
