In 2003, traffic control lamps (red and green) and pedestrian control lamps were switched from incandescent to LED lamps at 27 controlled intersections in Maple Ridge. Switching to LED lamps saw an 87% reduction in energy consumption, totaling a yearly savings of 402,672 kilowatt hours (kwh) of electricity. Grants totalling approximately 50% of the material costs for this project were provided by BC Hydro.
Since 2003, new intersections have had LED lamps installed during construction. Yellow traffic control lamps at the older intersections are also being replaced with LED lamps as the incandescent lamp fails. The yellow traffic control lamps were not changed to LED lamps in 2003 as they are not used as much as green and red lamps, so they have lower energy consumption rates and a longer lifespan.
