Having read people installing a headlight switch to help with battery drain when switching bike on to check stuff and to have more power going to the starter, I have been searching for of an automatic solution... until now ! (to borrow a line from one Mr Clarkson -from an old BBC motoring series)

I was watching this recently posted video and realised that the Latest new Himmi ( the one with the tripper ) has this automatic feature of headlights only coming on after the bike starts, much like my BMW :) !

Watch the video at 21.36 minutes onwards in- towards the end of the video to see this - 'you beaut' feature.


Does any one know if there is a retrofittable part that we can add to our older bikes to save our batteries.

I am thinking it is some sort of circuit connected to the starter switch which triggers a relay with a timer delay perhaps?
Any electrikery l whizzes or any one any ideas?

Probably a relay that is activated by the alternator. With the ignition off, there' s no power to the lights circuitry. Once you start the engine the alternator or RR will provide voltage to activate the relay. Switch the engine off again, no more current from the alternator and the lights go out.

The first injected BMW K bikes (bricks) had a "load control relay" which tried to achieve something similar , but they usually ended up switching of the ignitions too.
Intermittently!
Drove service technicians to distraction, as it did not show up on the scanner.
When someone finally discovered the problem BMW was left with a pile potentially dud relays which sat on a shelf somewhere until someone dusted them off, blanked out the part number with a Texta and fitted them to the first F650 GS 's, and we went through the whole pantomime again!@*!

I have recently fed a pair of spot lights on the misses BMW R1150GS via a relay which was energised by the alternator to help out the starter motor and save a drain on the battery when the engine is not running. worth a look at the Himmi wiring diagram.
