Agree with others regarding swapping incandescent lights in place of LEDs. You would need to carefully assess the wire size, fuse size, and heat resistance.
If you can find a make or model of the fixture you have it might help. LEDs come in a variety of colors and brightness ratings. However, finding something that would adapt to your existing fixture or be a drop in replacement may be more difficult. Dimmers are an option for some, but not all LED fixtures, but it may be difficult to install a dimmer or dimmers depending on how easy it is to access your wiring. You might be able to install dimmers at the wall switch location depending on how many fixtures you have on a switch and what type of switches you have.
In our travel trailer, I moved the over the bed reading lights down below the bedside cabinets and replaced them with different fixtures and dimmers, but these would look quite out of place in the middle of the ceiling.
