Yeah I know Barry, I'm pals with his big brother Colin.
The gauges point straight at me, as for cost I don't really know as they were in the car when I got it. The dials are white, just glow red with the backlight to match the cars dials. My Defi's glow white though...
You get them amber but having the white numbers didn't look odd in my Glanza!
As for settings I use the lowest ISO I can (64 on my camera) and use manual settings, long exposure, it differs from photo to photo depending on light conditions, and I was trying to take a lot of dif exposures as well to try make some HDR images. I always use my tripod when I've got it though.
