Hi there,

I backlit my MGB a few years ago and happy with the results. The backlight came with a 100ohm SMD resistor already installed and the brightness is perfect when using alkaline batteries. But when using rechargeable the brightness is significantly less. As I want to be able to use rechargeable and non-rechargeable batteries; my thoughts are to add a pot in parallel with the 100ohm resistor to be able to control the brightness.

An SMD pot could probably be glued just below the battery cover where the cover clips goes through. A small screwdriver could be used when needing to adjust it,

Has anyone done anything like this?

Thanks for any help.
