Help with gauge cluster lights

[Truck82]

Half of my lights behind the gauges on the dash don’t turn on. So I got some new bulbs, plugged ‘em in and… still nothing in the ones that didn’t work before.
I know absolutely nothing about electrical and need some help here. Are the sockets that the bulb plugs into replaceable?
Thanks all in advance!

Most of the time the printed circuit board is wore a bit where the bulb sockets twist onto the gauge panel. Sometimes, if you have a burnt spot in the circuit board, it'll cut off power to the bulbs beyond it. I did have a weird, rare instance once where I kept replacing the bulbs that wouldn't light up, but it turned out to be that the last working bulb was the problem as it wouldn't pass the voltage to the bulb next in the circuit. Try replacing the last working one in that area.

The twist-in bulb holders are replaceable. You can also take a pencil eraser and gently clean the area they contact the printed circuit. Also, if you are trying to replace them with led bulbs, be careful. They don't always work and don't mix well with standard bulbs.
