Nothing.
Well i actually went to fit LED replacements for the conventional bulbs in the interior/reading lamps.
Had bought several wedge 5w equivalent LEDs since these are used in many lamps around the car. Allegedly.
Except the reading lamps have bayonet bulbs and fittings.
I'm now wondering which other lamps have bayonet fittings instead of the wedge type that are specified in the user manual.
Sidelights (2), wing repeaters (2), numberplate (2) and high-level brakelight (3) are all wedge in the book.
I'll have a look at those when I've daylight free time. The package of 21w/5w, 5w, HB3 and H7 LEDs arrived yesterday.
