Try this. With the key off, step on the brake pedal and have a helper watch the brake lights (or you can back up to a wall and see the light yourself). Now turn the key to the ON position (but don't start truck) and see if both brake lights stay lit. If the left one goes out my guess is that you have some kind of short in the ignition switch, or some seriously hokey wiring.

I know it sounds weird, but cycle the 4-way flashers.
Sometimes the switch gets stuck in a midway position.
There are a number of things going on in the column.
