Welcome. As Leon said it is a horizontal drop in bobbin. You will want some sort of sturdy base or case for it.
You can find a manual for your machine at
https://res.cloudinary.com/singer-se...ng_Machine.pdf The instructions for changing the light bulb is on page 5 of the pdf and how to install the bobbin cover slide plate can be found on page 15 of the pdf. The slide plate is often missing as one tries to put it on sliding left to right instead of right to left.
I don't know if they have led bulbs for this machine, but more than likely there are. Also the lens covering can sometimes be tricky to remove and replace.
Have fun.
