[Roadsters] "B" dash light - circuit to nowhere?

[Gary McCormick]

Someone should be keeping a log of how often this question comes up.

The pretty red light in the "Brake Safety Lamp Check Knob" (as it is referred to in the Owner's Manual) is the Brake Safety Lamp. The light in the knob is activated when a) a failure (drop in pressure) in either the front or rear brake hydraulic circuits is detected, or b) you pull the knob out.

There is a valve block mounted on the firewall which the front and rear brake circuits are routed through. If the valve detects a pressure imbalance between the front and rear circuits when the brakes are applied, a switch is activated which lights this lamp. Pulling the knob checks that the lamp is functioning.

Is there some missing hardware that should connect this light to the parking brake? Should I wire it to the brake lights?
