65 dart can I get Led lights for it?

I notice the bulbs you linked to were red. Doesn't this cause a problem with a red bulb behind a red lens?
Absolutely not. The red lens is actually a filter that filters out the other colors and allows red to pass. An incandescent lamp throws out a broad spectrum of colors including red. A white LED pretty much throws out white. Putting it behind a red Lens basically causes not much light to pass through. See the picture in the next post after yours.
