You trying to get old Red lit up...LOL.
I think it is origional to the house..
Could date back to the 20's.
It's possibly time to get it rewired, but I would try to find those LED lights anyway. They work with a lot less heat and current, but you may not be able to use the dimmer.
Also, if loose filaments are the problem, new bulbs of the LED type will cure that as well.
