So, I was recently with a friend, and we were stopped at a signal. I then proceeded to say, the signal light is "open", this then led to an argument about whether it's open or on. I said open, because I view the signal light like a gate, when it's green the gate is open, when it's red, the gate is closed.
I thought it was traffic light? In any case, any light turns on. Usually filipinos say "the light is open"
my sisters would always say "open the light" in a room. i'd always correct them. it's "turn on the light". but with signal lights...um, "it's green, go".
i don't say "signal lights" and I certainly don't say the light is "open" or "on" red light/green light
Are you from the UK or something? Everyone I have ever known has just said "green", "yellow", or "red".
