How bright should gauge lights be??

X2

I have a dedicated ground wire back to a main buss for each electrical device rather than relying on chassis grounds and I never have ground issues.

I have a #6 Cu ring around my entire car that's bonded to the chassis, engine and sheet metal. I use it for lights, fuel pump, air pump, etc.....it terminates at the battery negative.
The ground ring is in addition to the normal grounding.

100% no ground issues ever guaranteed. :cheers:
