A black cab has one light. Now every business can
On means free, off means taken — and nobody rings the cab office to ask. Every other local business can now show the same light. Animated in-house; narrated with a synthetic voice.
What's said in the film
A black cab has one light. On means free. Off means taken.
You don’t ring a cab office to ask. You don’t leave a message and hope. You just look.
Every other trade in the country knows exactly when they’re free. They’ve just never had a way to show it.
So now they can. Plumbers. Sparkies. Salons. Dog groomers. Same light — same meaning.
Green means free right now. Not, we will call you back.
Speedi. Put your light on.
