A320 PAX reding lights

[MD83FO]

Noticed that after takeoff, the PAX reading lights reset button on the flight attendant panel becomes unavailable, any idea how to reset them in flight other than a CIDS RESET?

The R/L SET and R/L RESET buttons are inhibited in flight. The only way to switch them off is to do it row-by-row on the Seat Setting page. I’ve often wondered why those options are only enabled on the ground?

Because they're a test feature, not a flight attendant's convenience feature.

Qatar airways uses them for boarding, and switches all of them off before takeoff. Complete darkness.
