A signaling control device apparatus (10) comprises at least one LED (20)
having a light emitting surface (18). A sensor (24) is set to detect an
external light load (16) directed to the light emitting surface (18) and
generate a control signal indicative of a presence of the light load
(16). An electrical control system (14) detects the control signal
indicative of the light load (16) and sources an elevated current to the
LED (20) while the light load (16) is present. The elevated current
increases the contrast ratio making the signal perceivable by the users
as being in a particular state.
