2012 S550 Front Parking lamp left and right not working
 

Hi.My car was wrecked, so i installed 2 front headlights with all modules,and from beginning parking lights not working.I did teaching,learning,took it to dealership ,they was trying to do adaption and said there was a electrical software failure during installation.(all other lights working fine.)and now i need to buy 2 new headlamps !i removed the headlamp and didnt find that i can replace the bulb for parking, so i guess its built in?was trying to locate the fuse,checked fuses all good,may be i miss some,there is fuse location?So my question is it possible to replace just the bulb inside the lamp?or what can be the problem,wrong module?

Thx!
