<abstract id="abst" lang="en">
<p id="pa01" num="0001">The present technology is generally related to LED bypass circuits and associated methods of operation. In one embodiment, an LED bypass circuit includes a monitoring circuit and a switch. The monitoring circuit is coupled to the LED to monitor the differential voltage across the LED. The switch is coupled to the LED in parallel. When an open status is detected by the monitoring circuit, the switch is turned on to bypass the LED.
