I honestly don't see any issues with LEDs at all!
They are fully sealed, and won't break from vibrations. Just looks at your ordinary bulb (traditional and HID). They have an outer glass shell, that is fragile, and the wire inside that emits the light can snap in 2 at any time.
LED's have a very high efficiency grade, meaning they don't waste a lot of power...
For LEDs, it's just a matter of getting the right setup, so I'm with "tehdutchie"
