High beam switch

[darrsi]

Wot Bludclot said.

So on high beam you have both lights on and just one on low beam or both on low? Can you measure the current being drawn from the battery with the engine off? It should be about 5 amps per bulb,so I would expect 10A with both bulbs on. Obviously you're going to have more than this but if it's close to a multiple of 5A then your headlight might not be turning off the low beam when you switch to high. If the new switch doesn't cure it (and I'd try to measure the current before and after the switch change) then you're going to have to trace it through.

When the r/hand side is switched fully to the left my H1 single filament bulb would be on (as standard), but as i've had the mod done the lower filament of the H4 would be on too.


When reversing the bike down my alleyway between two houses i could see the upper/high beam light flashing on, along with the high beam dash display light, anything between a split second or a few seconds, then it'll go off again.
