Colour & Shape

Red circles prohibit

Making a security light with the added benefit of sound when activated is a great idea which already exists in the residential market.

I am unsure why this has not yet made the transition to the industrial market because this feature could increase the effectiveness of a security light product increasing the important surprise effect.

Who's There?

The personal aspect to security could create some interesting concepts.

Security objects which could convey human characteristics

Trips which trigger low level lights for example like a torch would perhaps convey an illusion of presence?

Using light and colour as warnings is not new, could something like this warn off criminals?

Colour Associations

Green = GO
RED = . . .

Some tests have proven that by adding blue street lights in city centres where there are high levels of violence it is posible to actually reduce the amount of violent crime.

Would red lighting have the same deterrening effect and cause people to stop what they are about to do?

This may be worth further investigation.

Road marking which act as territorial markers reinforcing the transition from semi-public to
semi-private but would conflict with road traffic markings.

Light beams

Is it possible to communicate to others that there are people present at different areas of a city or town?

Vertical beams of light which indicate someone’s presence in an industrial estate to others elsewhere is one way but has a number of different problems like levels of light pollution and disturbing planes.
