Rear defogger switch lights

['87 Turbo "T"]

Just got done cleaning up & testing my defog switch. Question is this.....

The on & off don't light up. Do I need to get two new bulbs(1 for the on & 1 for the off) & have them resoldered into the board?

I believe I do from looking at the set-up. Would anyone know the correct bubs? Would it actually be worth it?

Thanks!

Not likely the bulb. Probably the dimmer switch circuit. Does the defogger get warm? First push will be 10 minutes, after that, the second push will run it 5 minutes. After that, pushing the switch twice will shut off the lamp and the defogger.
