The amber is on the inside of the light, and I'm not sure whether or not it's a film that can be removed, but I'd strongly recommend against opening your lights up if you don't need to. You can clean them up and try to revive them, though. There are kits out there that you can use to clear up the plastic when it becomes opaque and yellowed. If you've already got a set of clear signaled lights, try and do that first.
