headlight comparison (bi xenon - halogen)

[pologti18t]

To be honest I notice the same thing when it rains. Why is that?

The bluer the light source the worse it is in wet conditions.

Amusingly I washed my windscreen the other day at night, on a back road. The amount of water from the Euro's headlight washers effectively switched the lights off for a few secs (due to water volume not electrical connection etc). An amusing game when youre bored...

I'll be sure to give it a try. Living in Pakenham ensures there are a lot of quiet back roads

The bluer the light source the worse it is in wet conditions.

So it's a result of the temperature of the light? The "hotter" the light is the more it's effected by wet conditions?

That's why fog lights are very yellow. High colour temperature light reflects back from the water particles and makes visibility worse.
Not sure about the physics of it but likely to do with wavelength and total internal reflection in water particles of a certain size or somesuch...

In fact, for cars like the new VW Jetta the option has disappeared altogether.

I checked at VW Camberwell today and the sales guy told me that xenon lights will form part of an option pack for the MY13 Jetta.
