Change from halogen to LED in WoWa

I would like to modify my existing, standard 12V interior lighting for the Puck L with LED lamps. Since Eriba has shown once again with my only 5 years old Puck L, that despite astronomical prices you still like to install nostalgia technology, these lamps must be AC and DC-suitable. In the 3 flat underbody lights are each 2 pieces G4 halogen lamps of each 10W and the two swivelling construction lights are also equipped with MR16 halogen spotlights 10W each equipped. (light goes differently…) I would like to exchange the 6x G4 halogen lamps for flat G4 LED “dishes” of approx. 2.5W each. There is already a larger selection, which I could also accommodate spatially in the luminaires, but it does not always stand in the technical data, whether these are also suitable for AC. With few lamps stands e.g. 12-30V AC/DC, but with many others only stands for e.g. 12V. therefore my question to the LED experts: can these LED lamps basically also be operated with AC same question then for MR16 (G5.3) LED lamps…
