Headlight water jet logic??

[Stuno1]

Mine have activated 2 or 3 times but no idea why??? Is it every x sprays they activate? Length of one I hold down the water spray button for?

They spray only when the lights are on and every 5th time you spray the windscreen.

Have you read the handbook yet? 

[Stuno1]

Oh ta makes sense. Only the bits I cared about ?

thanks chap.

I tend to flick the lights off before cleaning screen, otherwise the headlight washers just spray water all up the bonnet

You're not the only one.

Now I know I'll be doing that as well. It's a serious deluge of water when they activate.

When I went to see Craig Moncrieff (formerly of Murray Motors) about the lacquer on my headlights starting to peel, he said that one of the causes is thought to be if you have a high concentration of screenwash additive in the water, which could explain why the peeling started at the top edge of the light units as the water will gather there in the airflow. Since then, I've cut down on the mix and switch off the lights (if I remember) before I wash the screen.

See, they could have saved some weight and money - I also do everything I can not to wash the windscreen with the lights on. Have event thought about pulling the motor connection. Complete pain headlight washers.

Washers are a legal requirements (as is self levelling) with xenon bulbs.

Really, My Merc and both our minis are newer than the Evora and none have headlights washers. Both Minis have Xenons.

Part 6.2.9. "Other requirements" says: "Dipped-beam headlamps with a light source or LED module(s) producing the principal dipped beam and having a total objective luminous flux which exceeds 2,000 lumen shall only be installed in conjunction with the installation of headlamp cleaning device(s) according to Regulation No. 45.”

My mistake. Sons does have washer - relatively new and I hadn't noticed them. Wifes definitely doesn't but I'm now wondering if they are not Xenons - they are HID and self level  (am I being a numpty and not understanding the difference):

That's a very shiny Mini! 

[Colin P]

All my cars are very shiny - it's why I can't tell whether they have headlight washers.

  For the Mrs perhaps!  

Her headlights are LED - but that still seems to come under the above rule . I'm sure Mini know what they're doing.
