Topic: how many volts are supposed to be running the running light?

[J.Webster Designs]

hey guys.... how many volts are supposed to be running through the running light system? (solid brown wire) is it supposed to be a full 12V? (or in my case 11.59 without the bike running) Or should it be running less voltage to allow for a dimmer light?

The entire system is 12V.  Actually, 12 to 14.5V.  Bulb brightness depends on the filiment type.  The higher the resistance, the dimmer the bulb.
