VF;

I would agree that seems odd...and I have no explanation for it other than the bulb might have coincidentally have burned out, or the sensing switch at Handbrake coincidentally went sluggish, or an associated electrical connection might have been mechanically disturbed during the bleeding operation and have gone open...all might/should be answered depending on what you find when troubleshooting...I'd start by first checking the Indicator again, by earthing sensing wire at Brake Diff Sensor (Ign ON!).

Good Hunting!
