Head light problem 2002 Scenic Cruiser

[RayChez1]

First noticed that one head lamp only had one light that was working on dim. On bright all lights were working until today. I noticed while driving from Las Vegas to California that every time I tried to switch from bright to dim that a little red light flash would occur on the instrument panel. So when I got home I noticed that only one light was working. Need some experts as to what could be happening. I got under the coach and took the rubber cover off one of the lights hoping that it was a twist and change type bulb, but to my surprise it is like a very complicated system and it could be on whole sealed halogen light. Has anybody changed these type of lights or could it be a direct short some where. I checked the fuse and it is ok, but I am not sure if there are other fuses on the line next to the light. It says on the beam that it is a VO H1 light.
