High beam indicator

[packer]

I just bought a 72 shortbed that runs great the only problem I have noticed is when I turned the headlights on the indicator for high beams was on when the low beams were on and got brighter when I turned the high beams on, I figured it is a bad ground but thought I would ask before I started looking, I searched in this forum and didn't see anything, the headlights work fine, just the indicator light is a problem. Thanks

Does the dim light go out when you darken the dash light?
There's little cardboard tubes that block the light from the other lights from getting to that lens... if it is missing, it'll be dimly lit.

I checked and it does dim when I dim the dash lights also it is still on with only parking lights ond dims then also, so are these cardboard tubes inside the instrument panel assembly and where can you buy them?
