Why are some lights on buses blue?

[jonnoman]

Ive always wondered this.....

One , it's supposed to have a calming effect , and secondly it makes it hard for users to find a vein x

if you mean the ones inside the bus near the driver, its so the driver can see out better when driving at at night, or thats what i was told lol
