3 amps, I think is on the low side?! I replace all mine with LED's as well as all the running/tail lights.
I think the dash lights are fused along with the running/tail lights. I know when the fuse would go on mine, I had a line going to the back lights shorting out, and it would take out the dash lights as well. For many years that is how GM would do it. No dash lights, no tail lights!
