Anyone interested in this conversion should note the following:
I installed a kit with the slim (digital?) ballasts. These have a space-saving advantage and in my case, also ignite the lamp instantly (which means I still have a functioning high-beam flash function, albeit a bit dimmer and different color than when the headlamp has warmed up.
A bit of research appears to indicate that the big ballasts not only take longer to warm up and actually turn the light on but they draw a lot more current during initial start up. This means it may not be a good idea to wire them straight into the factory harness as I have done with both my oilhead GS and airhead RT.
