Depends if you want to use the lights to see with.
If so then FORGET H3-LED-"bulbs". To get anywhere near the light the Halogen H3 offers you will need close to 1300 effective lumens. This will ime require in the region of about 20W. And believe me the lamps will still get warm. I have converted Triumph lamps to LED - but the lenses are cheap and getting a proper focus on the LED is time consuming. Remember the Triumph lamps are FOG lamps - meant to give a wide & not far reaching beam.
Beam patterns - Long Range lights are useful where you have wide open roads. Twisty leafy lanes not so much.
