LED for brake indicator

70 Duster with Rallye Dash. I want to put LED bulbs in all the indicators. I realize they have to be orientated correctly and got them all figured out except for the brake indicator light. It connects to two pins, does anyone know which way the bulb goes in? I got the steering column out also, so cant really put it in and try, and don't think I can get my hand up there after everything is installed to change it.
