Had brake light out on corsa D 4 door. Found uts single filament being both tail lamp AND brake light. Weird but hey whatever. But why has the other (lower) tail lamp got 2 filaments? It's not a fog lamp my first thought. As a spin off the fog is the lowest one on the cluster and I noted that the nearside one wasn't lit, took it out bulb is fine so why is that event there.

Vauxhall is confusing me with some if these ideas
