  "textContent": "A failure detection circuit capable of detecting an outage for a hybrid turn signal lamp is provided. The failure detection circuit is capable of detecting the failure of an incandescent light source and an LED light source and capable of sending a single failure signal to a body control module (BCM). The failure detection circuit includes an outage detection module connected in series between a power supply and an incandescent light source. The failure detection circuit also includes a lamp driver circuit adapted to detect a change in LED current or voltage that is indicative of a LED light source failure and thereafter output the failure signal to the BCM.",
