LED headlights

Hello Together I own a Harley Davidson Sporster Forty Eight from the year 2018. Now I want to completely replace the lamp at the front and mount an LED headlight. On the internet I find only “favorable” models, which cost around 40 – 100 Euro. I asked two dealers (Switzerland), one told me, including assembly 850 Francs (850 Euro) and another about 700 Francs. Now I wanted to ask if someone changed this also at a dealer, and above all How much he paid for it. Of course the LED must have a test mark (TüV, MFK). Thank you in advance for feedback.
