Class 86/2.... Am I Missing Something?

Just on my first run with the class 86 and can't turn the headlight on?

As can be seen from the images the both the marker and headlight switches are on (3rd and 4th from the right) but the headlight isn't lit? Does something else have to be done to get the headlight to work?

 

got the lights on. turn on my train all switch to on above the flash light. to the right?

 

Yep as per the first image both the marker light and headlight switches are on (The rest are all off)

 

Change the bulbs?!! - it's a new TSW6 feature 'leaked' early!

 

Realised they are on but just not really visible in bright sunshine.

 

I also thought this. The difference is more noticeable when you turn it off again.

It's like trying to see if the headlights of the DB 103 or 110 from Koblenz Mainz are on.
