TR6 TR6 dash lights not bright enough

I would think that one could find a newer better quality rheostat. I looked at my customer car last night as the dash is out and looked at the schematic.
We need to know what the current draw of all the dash lights that are controlled by the rheostat. Then we can spec out the replacement part. As the gauges are all out, I could not easily do this last night, need to ground the bulb holders to complete the circuit and measure the amperage draw.
Has anyone already did this?
 
Stock bulbs are rated at 2.2 watts and I count 11 of them. So pretty close to 2 amps at full brightness.
 
I was not happy with the dim lights either, so I took all the gauges out, took them apart, sanded the interior, and painted gloss white, got rid of the plastic pieces that are suppose to give it a green or blue hue, and put new original bulbs in, experimented with LEDs, they dont work and are not designed for cars with reflectors, and now I can see the gauges at night
