Claim 0:
1. An outage detection circuit, comprising:
a current monitor electrically connected in parallel with a lamp, wherein the current monitor is operable to determine current supplied to the lamp;
a sense resistor electrically connected in series with the lamp; and
a load element separate from the lamp and electrically connected in parallel with the current monitor and the lamp, wherein the load element, the current monitor, and the lamp are electrically connected in parallel between a power supply and a ground reference;
one or more switching devices responsive to the current monitor and electrically connected to the load element, wherein the one or more switching devices are operable to adjust current through the load element according to input from the current monitor, and wherein the current monitor is operable to control the one or more switching devices to change a current flow through the load element when the current monitor detects a change in current flow through the lamp.
