tunnel lights
-
anybody knows why the street lights in the tunnels' start and end are amber, while those in the middle of the tunnels are white? -
so that our eyes wont have to adapt too quickly?

So that it wont blind you when you get into and out of the tunnel.Originally posted by sinicker:so that our eyes wont have to adapt too quickly? -
You can post your question to LTA. They will explain to you the reason.

The contractor they hired ran out of that colour.

If you go other countries' tunnel... it will also have simply amber/white lights combination. it's for eye adjustment.
But the funny thing is... when i go other countries's tunnel.. it will really remind me of singapore..
the same lighting, the same ventilation, the same lane open/close signals.

the amber lights are for our eyes to get used to the different level of contrast..
from a super bright environment to a dark environment, our eyes cannot adapt too quickly and thus cause our eyes to lose focus... -
next time when you leave the tunnel, try looking back at with rear view mirror. you will see that the tunnel is really damn dark without the amber lights.Originally posted by zerocool85:the amber lights are for our eyes to get used to the different level of contrast..

You are right. The boost lighting is to let the driver adapt to the tunnel lighting when entering and exiting the portal.Originally posted by zerocool85:the amber lights are for our eyes to get used to the different level of contrast..
