In my experience, you have to be careful trading out LEDs into a refelector/diffuser assembly designed for incandescent. Case in point: I have the Kisan Tailblazer flasher lamp which upon brake application begins with a fast flash and then slows. The initial flashes are not very distinct with the halogen lamp in the flasher. An LED would show the flashing better, so I was excited to try the LED replacement lamp from Kisan. It ended up being much less visible in the housing, since it only projected in one direction and didn't fully illuminate the lens diffuser. The reflector is designed to capture the side spill light from the lamp and project it out, lighting up the entire lens. With the LED it was more like a point of light in the center of the lens.
I had a similar experience with another bike that had LED turn signals when purchased used - when I replaced the LEDs with a regular lamps, they appeared at least three times brighter. Of course, there are many different kinds of lamps out there. If you do go the LED route, you should probably look for lamps that project all around as well as straight out, and get the brightest you can find.
