I have an Athern Blue Box S-1 switcher. The headlight bulb has gone out. Since I run DC the light is only brightest when at full power. I rarely run more than 35% power. Is there a way to install a new bulb that will be at the brightest whenever the loco is moving? I would like to do this to all of my locos if I can.
