What you have is perfectly normal and you should be going through any problems. Its just the type of connection you have with Comcast.
The upstream light [F] is neither red nor green. It is amber. The link light [D]flashes amber. All others are green. When it was installed , all lights were green except the link which always flashed amber
Amber. Red. Its the same thing pretty much. You only need to worry if the light is flashing or not on at all. If you really feel concerned about the amber light, you can try to bypass cable splitters, cable extenders, ect. That would give you the best signal possible to the modem and may turn the light green again. Other than that it will still work perfectly with the Amber/Red light located on the US light.
How are you going to give this guy a hard time about reporting that his light was yellow and not amber when you can't even spell the word wasting, maybe you should have consulted a dictionary before posting... no, wait, Comcast has a SPELL CHECK for posting messages.
