Which XB headlamp - Lightning or Firebolt? I'm assuming it's the Lightning since you mention the 194 bulb, which should be a daytime running light. I can't speak for the Lightning, but the firebolt has the lowbeam on at all times. I would suggest against putting LED bulbs inside the reflector as signals, as they will not be seen when the headlights are actually on and they could be mistaken for a flashing headlight instead of a signal.
