Night Signals

Chevrolet transformed its OOH media into functional safety infrastructure with "Night Signals". By day, these are standard ads; by night, advanced retro-reflective materials reveal vital traffic signs activated by vehicle headlights. This repurposing of existing assets turned passive advertising into active road guides. To scale impact, Chevrolet shared the tech as an open platform with competitors and the government. This deployed, scalable system led to a 28% decrease in highway accidents.
