A Daytime Running Lamp module provides a fully automatic Daytime Running Light function by operating the vehicle's front directional signals steadily, except when they are flashing as turn signals. This DRL implementation complies with US and Canadian DRL performance requirements, and has major advantages over headlamp-based DRLs. Because directional signals are legally required to shine light in a wide angle, the DRLs are visible through a wide horizontal angle for maximum conspicuity and safety benefit in avoiding angular collisions with pedestrians, bicyclists and other motorists. Turn signal bulbs cost much less, consume much less power and have a much longer lifespan than headlamp bulbs. There is no undue glare with turn signal DRLs, as can be a problem with headlamp-based DRLs... All of the vehicle's original lighting functions—turn signals, hazard flashers, parking lamps, etc.—carry on working as they always have.
