@Krish123; LED headlamps were an extra cost option on SE models and above in 2017; page 20 of
brochure at the link below. That was when the model range consisted of just the S, SE, FR and Xcellence;
They’re standard now on FR models and above. I think they became standard when Seat dropped the entry level S model and expanded the model range from four to six models (SE, SE technology, FR, FR Sport, Xcellence and Xcellence Lux) but I don’t know exactly when that happened.
Brochure at the link below is dated Dec 2018 and LED headlamps are listed as standard equipment on page 4 for the FR and above.
