Wait, is it the brake light on the right side of the cluster? If so then that strangely enough is like a warning light for having low voltage in the system. Also, it seems that a bad ground will trigger that as well, my battery was charged up just fine but I had left the ground to the intake manifold from the battery box off and I got that light, and the same symptoms you have. I connected the ground and presto, works great. I'm still guessing its the battery though.
