Okay last weekend I changed out all the bulbs in the gauges on my new to me '73. I replaced the standard bulbs with equivalent LED's and cleaned each socket and bulb housing the same way in the process.

This evening was the first drive I took after dark. What I noticed was that both the fuel/oil gauges and the speedometer were the brightness I'd expect but the remaining gauges were all equally extremely dim to the point that I had to look carefully to see that the bulbs were illuminating. They all were but something is not correct.

Any ideas??
