IT DEPENDS WHAT THE CIRCUMSTANCES ARE, LIKE MAYBE UMM, I DONT KNOW, WHERE YOU ARE!?
GEEZ, LEARN TO SPELL TRAFFIC!
Oh, I'm really sorry... i suffer from imense rage blackouts.
A yellow traffic light means to slow down or stop completely. When the light is yellow it is about to change to red in a few seconds. Contrary to popular belief by many drivers yellow does not mean speed up.
It takes 2-3 minutes for a traffic light to change from green to red! (P.S I have counted the seconds myself!)
changes twice per minute, 120 times per hour, 2880 per day, 1,051,200 per year
You don't have to wait any amount of time when the light turns green, when the light turns green that means the intersection is safe for you to proceed.
About 1.5 light-seconds to the Moon.
By "amber" I assume you mean yellow. A yellow traffic light indicates that your "right of way" is ending within the next couple seconds. When the light turns yellow you shouldn't enter the intersection if you haven't already, unless you've reached "The point of no return". It's not illegal to go through the intersection while the traffic light is yellow, but if you can stop you should, if you can't stop then go through the intersection (determined by your own judgement). A yellow light is basically a warning of a red light coming, where it is illegal to proceed through the intersection. The duration of a yellow light depends on the road the traffic light is governing. For a side road the traffic light may only show a yellow for around 3 seconds, for a major road such as a state road or US Highway, the traffic light may show a yellow for 4-6 seconds. These timings all depend on the road that the traffic light is governing and what the speed limit is for that road.
Light seconds is a distance not a time.

A light second is a unit of distance, not a unit of time.
According to Federal Guidelines 3 seconds is the minimum recommended.
It is five seconds
A traffic light in Jakarta, Indonesia has a 300-seconds timer. If you are unlucky you have to wait for 5 minutes there. A traffic light in Sofia, Bulgaria at an intersection between a main road and a small one used to be constantly red for the cars coming from the small one. The only way to get a green light was to get out of the car and press button for pedestrians. The traffic light was repairer 5 months later.
