Unnecessary replacements of Xenon bulbs
|
Saab 9-3 and 9-5 with Xenon lights.
OK Xenon bulbs have been wrongly replaced.
Perfectly functioning Xenon bulbs have been replaced as customers have
complained about a colour difference between the two bulbs after one has been
replaced.
When this type of discharge bulb gets older a thin coating will cover
the inside of the bulb. This coating will slightly change the visible colour
spectra of the light from "white" to "blue" during it’s first year and
some customers will observe this colour difference when the headlamps are
turned on.
There is no need to replace a Xenon bulb because of the colour difference
between left and right bulb. The lighting quality is at the same level for
both the new bulb as well as for the old bulb, despite the slight difference
in colour. As the new bulb gets older the colour difference will decrease.
No warranty claims will be accepted for unnecessary replacements of
Xenon bulbs.
