Bulb Change - Seat Leon 2012 Owner's Manual

Bulb change

General notes
Before changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a re-
duction in the bulb life and condensation on the mirror surface, thus reduc-
ing efficiency.
A bulb should only be replaced by one of the same type. The type is inscri-
bed on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle.
Main headlights
● Dipped beam – H7
● Main beam – H1
● Side light – W5W
● Turn signal – PY21W
1)
On this type of headlight, the bulb changes must be made by the SEAT dealer, given that
complex elements must be removed from the vehicle and a reset must be made on the au-
tomatic control system incorporated.
2)
The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3)
Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.
4)
Only in the LED light models. The LED modules cannot be replaced. The other lights, turn
signal light, fog light and reverse light can be replaced. If the warning lamp for the brake
light or side light (LED lights) lights up, the tail light assembly should be replaced. The fail-
ure of the lamp is only shown when the LED function goes out completely. Sometimes, a
LED will stop working, without displaying the warning as the function continues to operate.
