Thanks guys. I was able to reach under the dash and replace three 194 bulbs (one bad, two others probably on their last legs) with Sylvania 168LL bulbs. The last time I replaced a bulb in the truck was in the late 80s/early 90s, and some of those that I replaced this week may actually be original equipment!

The 168s are still not very bright, so next trip I may pull the panel and "brighten up" the inside of the bezel. I did something similar on my 82 truck. Instead of paint, I used aluminum HVAC tape. It made a noticeable difference.

On a related note, just replacing the OE wiring harness, fuse panel, and most connectors on my 82 increased the voltage to the instrument panel by nearly 2 volts (!) under load. Same is true for the headlights, so no headlight relays are needed!
