Minor Vintage Repair?


I've got a 40 year old Toshiba SA-2500  25 wpc receiver I got back in high school. Mid-fi at best in its day but well reviewed in its day and well reviewed recently by vintage audiophiles. It is in good shape and I use it regularly down at my country place. However, the light behind the station indicator is burned out. Without it you can't see which station you're on and you can't tell when the unit is on or off. The clear plastic indicator moves back and forth on a cable moved by the tuning dial. There is a wire that goes to it that presumably provides the power to the light but I do not see anything there that looks like a conventional light bulb.

Anyone have any idea how I can fix this? Probably not worth spending the money on sending it to anyone for professional repair.

Something like these?

I don't solder well but I can do it.

I also don't know what 'in series' means.
Does that mean: source wire (positive or negative???)-->resistor-->bulb for each of the three bulbs?
@imhififan The link shows a picture but doesn't say what those are. I'm assuming they are wire clips.
I think they would need a resistor as mentioned above to lower the voltage (or whatever) otherwise I think they would just fry.
