Air Direction Wheel - Needs Lighting

[tomroscoe]

My Zetec 100PS has that big rotating knob ahead of the gear lever that directs the air any which way. It's a bit of a clunky thing and I'm glad I haven't got arthritic fingers because it's hardly 'camera control' precise, is it?

Anyway all the various locations are nicely back-lit at night but the big problem is the white indicator line isn't, so with a quick glance down it's very difficult to see where the air is actually being directed, or where the line is when you turn the dial.

Anyone had any ideas as to how to light this indicator line? I've thought that an extension of the red LED line above the glove box might work, or an LED fitted below the 'passenger air bag' sign might beam some much-needed light down.

Luminous paint and a fine brush? Lol
