Led change in dial cluster

For removal add extra solder to both pads then heat each side quickly and it will slide off

always use solder to melt solder, heating dry solder will take longer and be less effective
 
I haven't touched it, didnt know there was an option to alter the brightness?
 
Same here, I know you can adjust the brightness of the RNS-E display but not the instruments?

Where is that option?
