Change light bulb in headlight

Hello together… Sign me up from the Golf 1\2 forum here with you since I need your help…. So a work colleague asked me if I can exchange the glow bulbs in the main headlights with her….she thinks you have to remove the clothing so bumper? can’t be or? find absolutely nothing about the search…so you can tell me how to take the smart so apart that I can exchange the glow bulbs? where which screws out and so…. H7 bulbs would have to be that or? she just tells me “in the board instruction is only under lamp change “let this please just make in a smart center`lol ” hm.. hope you can help me? gruß
