Check the easiest things first, is the signal light wired properly? Check that the wires go to the right terminals and that your jumper is in and every connection is tightened down.

Check that the plug on the bottom of the light is all the way in. When we tightened our light down last year, the plug would pull out ever so slightly and stop the light from working. Easy fixes are great because they have very little time involved.

If your LED is blinking on the sidecar and the amber RSL isn't that seems to point to wiring between the sidecar and the amber RSL, or a faulty RSL. Check it with a RSL from last year maybe...
