I have a Leon FR 1.4TSI, I have tried to find what kind of lamp bulbs there are for the licence number plate but no information in the manual. I want to change them to LED ones. Any of you guys who knows?
Are you sure you haven't got led ones, the led ones are not just the standard type fiting with a 32mm incandescent festooned which seat changed to a led festoon bulb
They are a complete sealed unit with two smd type leds soldered to a green circuit board
So your options are, see if you already have leds, there is a small plastic catch on the number plate light, push it in and the light unit will drop out
If you haven't got leds then you probably have the standard unit with a incandescent festooned bulb and you can change it to led, although you may need to recode the unit with vagcom to stop any bulb failure warnings on the dash
Or buy the complete led light unit from a Seat dealer and fit that
