High beam is an H1. Yeah I remember there's a mistake in the handbook. And not the only one!
Note getting at them is extremely fiddly, top fairing panels off, and if you drop the H1 into the bottom of the lamp unit it requires taking the unit out to get it out again, guess how I know
Not sure about LED's, but I changed my H1 (the main) to a Philips X-treme, also did the wiring mod that keeps the dips on all the time, was proper impressive on a dark country road.
