I have a record player from the 80's.
There is an orange neon bulb 12v above the platter.
There are slits in the platter.
There is a light sensor underneath the platter. Depending on what patter of light is coming through, the player will know what size record is on the platter.
Pic related is the player. One of those three sets of slits is open (other two are just for decoration symmetry). The light for the lamp comes out of that semi-rectangular cutout on the left side at the back of the player.

https://www.youtube.com/watch?v=McG9IC9zibQ is some guy fixing one. You can see the lamp working at around 6:30. It's the one sticking up like a spotlight at the back.
If I can't find the OEM bulb, or even a close enough match, can I use a different type of bulb? (LED?)
Thanks. I'm not a tech dude, just fixing my dad's old shit so I can use it for myself. But I enjoy learning about it all.

Here is the schematic of the power supply section, including the bulb. The part number in the schematic is 65e02013s01, but that doesn't bring anything up on google. The bulb in the video looks like a generic indicator bulb that you can find on ebay and various online shopping sites.

Can you post a picture of the bulb itself?
Also, please do a quick test: tape a torch/flashlight where the bulb should be and test with different sized record, just to test if the LDR portion (the detector) is working. Just to be sure.

The schematic can be found on Vinyl engine if you need the rest of it. To answer your LED question, to do that you would need to find somewhere else to piggyback the LED in another part of the circuit that has lower voltage and DC current, since by the looks of the schematic it is hooked up directly to the 120v center tap on the primary of that transformer. Neon lamps require higher voltage to glow than LEDs
The most straight forward and simple way imo is just to get a neon lamp assortment like this, and find the size that best matches the original.

Flip to the back of the service manual, there is a parts list.

Literally any neon bulb you can find will do the job. These are one of the least sophisticated components you'll encounter, and are easy to source through any of the dozens of online parts retailers out there.
