Hi All,

I replaced the bulb in my B&M headlight (I believe it's the N2 plus Standlight) the other day. The new bulb is from another of the same light, and works fine BUT

• the standlight no longer works
• my taillight no longer works.

The taillight is wired to the front-most connection of the headlight (there are three downward-facing prongs on the light) and to ground, using a single wire to the back of the bike.

Has this happened to anyone else?

I feel I may have loosened something inside the light when replacing the bulb.

Did you change the wiring when you replaced the bulb? If not, you know you didn't mix up anything; if so, check B&M's literature for how the wires should be run. Did the taillight and headlamp-standlight continue to work with the blown-out old bulb? If so, you know that circuit doesn't rely on current through the bulb; if not, maybe it'd be worth it to try out a completely new bulb.
