Is the LED kit exactly same for Seat Leon 1p ??
Im not sure mate.
Just go round all the bulbs and check which type they are. They will be either,
Capless wedge bulbs (CWB)….
or Festoon bulbs (FB)….
The Festoons on the Gti are all 36mm apart from the one in the Boot which is 42mm.
If yours are the same as the Gti there should be…
2 in the Front Map light (CWB)
3 in the Rear Map light (CWB)
2 in the Footwell lights (CWB)-Canbus.
1 in the Glovebox light (CWB)
2 in the Sun visor lights (FB)
1 in the Boot light (FB)
2 in the Numberplate lights (FB)-Canbus.
Let me know what type each bulb is and we can go from there.
