w124 question

[blk90s13]

wanna change my headlights and wanna get rid of the headlight wipers

I found headlights made by depot looks decent searched here people say they ok to have ( anything beats stock )

wiper panel I cant find a place that stocks it cheap

what is involved with changing the headlights ? I can do lots of stuff but I Wanna be prepared how long will it take etc any special tools I read vacum lines to headlights ? no clue what that is


is there a write up on headlight removal and install on the w124 body ?
