You should have all of the following for all the lamps (followed by the respective bulb name):
KALTUEBERWACHUNG_
KALTUEBERW_
FEHLERMELDUNG_CC_
WARMUEBERWACHUNG_
WARMUEBERW_

The last 2 are for warm monitoring. I assume you'll need to change those as well but you might know better than I do. I've never replaced bulbs with LEDs.

Thanks for the reply e90drvr!
