The car I drove for quite a few years when delivered to the Scandinavian market had a different battery arrangement despite being same engine and mine having the same preheater. No differences in electrical options or accessories. I suspect it was to allow for much greater use of air con, defogging, heaters etc.
This doesn't happen with bikes because no need to set them up for riding in -10 or -15C.
But the high load and cold has a huge effect on the battery and a start on a cold morning is quite telling. That's why I wouldn't put the 20A 200CCA battery in my K. Too marginal in our climate although 99% of the time I would get away with it but I want 100%. On the Honda it would happen after a run that I used the lights on there wouldn't be enough in the battery to start the engine again....but it had a kick start so that was manageable.
Trouble is the place BobT lives in is warm enough there won't be a heated grip or heated suit in sight.
I too had to deal with needing extra light and it made such an amazing difference it was worth it. Sadly my experience to date with LED lights etc is that while they can be vastly more efficient the lumens don't seem to be where you want them.
When I popped the 160W H4 in the K it was awesome and the early K isn't all plastic so will take it. I have the ceramic bulb holders and relays and it was better than any of the cars.
On the Honda I wired the extra lights to the original wiring but with a switch so there was an option to have them on or off when using full beam, wired through a separate relay. Like the K it didn't have any relay as standard so it was easy and just ended up with two relays.
