Hello, I would like to ask for some advise regarding my good old Fazer (FZS600), which for many months now  (3-4) has a problem with electrical circuit, particularly with headlamps.


Bike has installed an Oxford heat grips and DataToolDemon Evo immobiliser - which I guess may contribute to the problem


Recently it started to happen more frequently, but strangely, when I start to ride the bike for 10-20 minutes and rev the engine a lot - the headlights start working again, but later occasionally they go off (for like 30-60 seconds, when I'm riding the bike)


Can anyone advise if there is anything I can do myself, before I take it to a workshop?
I obliviously tried changing fuses already and it's still the same 

For couple of weeks now the engine oil warning light occasionally comes on, it stays on for around 30-50 seconds and then it goes off. It's not the case that it's happening when sharp turning or going up\down hill. I spoke to my mechanic about it it and he is not sure what is causing it. He said that it may be a problem with a oil sensor (maybe it got some gunk stuck to it), but wasn't sure and he said he it would be quite a lot of work to check it\clean it, he would have to remove the whole exhaust system to do it and probably it wouldn't be cheap. Does anyone know what could be causing it and is it something serious? Is it safe to keep riding the bike if it keeps happening?

Is it me or the original headlights in FZS600 '02 are extremely poor on dark roads?Can anyone advice how to upgrade it? Are there a brighter bulbs available for this model that won't melt the plastic cover; maybe some LEDs? I asked my mechanic about those and he said that it would cost around £80, which is way above my budget. Is there anything cheaper or is there any other solution? I heard that there is a MOD for Fazer Boxeye model that improves its headlights; maybe there is something similar for Foxeye model. Or maybe there is a decent set of spotlights available?
