I did the h4 bulb with heatsink conversion on the beemer to reduce the load on the rotor/alternator, as you know the Bosch system is the weakest link on Guzzi/Bmw.

I've heard some northern neighbors complain of condensation issues in the lense.

Mines new enough (2000 Jackal) that it's got the brushless System which is fairly reliable, but unlike the Bosch or Marelli system, it needs to be almost up to road speed to knock the indicator light out its fault bulletproof unlike the Boach rotors dying..,

My old ambassador has the Marelli 350w generator with the mechanical VR. It's also 350w rated. If the bike was runnable, it let it go till it quit then mount something else in its place...
