I have a 2016/17 Octavia SE Sport and wondered before buying boarding lamps, whether there is a connection for them within the lamp assembly. I am also thinking of fitting dynamic indicators at the same time. Any help or advice much appreciated.

What do you mean by boarding lights?

Not a term I have come across on VAG cars. Do you mean the light at the bottom of the door card? or the downlight in the door mirror? Interior lights come on when getting in the car?

Downlight  door mirror leds

I think they're more commonly known as puddle lights
