Abstract
Brake pressure indication apparatus in a vehicle includes a plurality of red L.E.D.s arranged in a ladder-like configuration. The L.E.D.s illuminate progressively in response to brake pressure. As brake pressure is increased, more L.E.D.s illuminate. Brake pressure may be sensed in either of two ways, such as movement of the brake pedal or the expansion of a flexible brake hose.
