If you turn on the headlights (without using the autolight function... i.e. the conventional way).. Then it goes back to the "2 stage" high beam.
As Cliokhunt says, if the auto headlamps are enabled there is no half way click on the stalk, but when you physically turn the headlamps on with the stalk you will now get a half way click
Pull it back halfway to flash , its a fine line between pulling the stalk back and flashing and putting your full beam on ,i've blinded a few people lol .
