My car is Octy 3 1.4TSI ambition with the normal headlights , is it possible to install the LED headlights instead of the original and do they need anything special to be done or just plug and play?

You can't get LED headlights - only LED DRLs with the Xenon headlights. And no, they can't be retrofitted as far as I'm aware (certainly not cheaply or easily).

LED DRLs with the Xenon headlights

 

i meant those , the default ones for Octavia Elegance

I thought the Elegance came with Halogen lights as standard - iirc only vRS and L&K come with Xenon as standard although could be wrong.

 

Might be worth searching this forum for it as it's been covered before.  The general wisdom seemed to be it was financially prohibative if it was even technically feasible.

 

I can't imagine the Xenon clusters are cheap, then there's the self leveling and self cleaning systems if you dont have them plus all the wiring.
