The interior lights are all LED's but always have worked just like stock lights, fading in and out when the doors are open/closed, today they stayed on for an extra 20-30 seconds or so before fading out.[/QUOTE]

since the lights do not have fuses of their own, the LCM shunts off the lights that give problems to the LCM.. the visor lights are not on the LCM, they have fuse... when the issue is rectified, the LCM provides juice to the circuit again... sometimes, you need to "reset" the LCM.. there is not an actual reset procedure, but cycling power sometimes helps, as the LCM scans the lines again...
