It probably has those grain of wheat bulbs available in 12V and better in 14V
The Volvo switches use them and they thread into little plastic twist lock sockets.
There's no soldering, just carefully thread the leads through the little tracks
and cut off the little extra and you're done.
In some radios they are soldered in.
Try to find the 14Volt bulbs since they outlast the 12v bulbs in a 14 volt car.
The other thing is run your dimmer down on the low side, it will extend the life of your bulbs. Over voltage kills filament bulbs.
