Blue Lights

Col i'm pretty sure you can set the lights to come on at whatever revs you like, or you can switch them off altogether,my bike must have been set pretty high, but the one i had a test ride on must have been set at the lowest setting as it was always on and it got on my nerves!

 

As DD says, you can get into the settings and change the rev speed at which the blue lights illuminate.
I have mine set to 9,000 rpm with the progressive strobe type setting, this means that actually start coming on (one light) at about 6,500, then progressivly more illuminate as the revs increase until all are lit and flashing at 9,000.
I do this before it redlines, plus I have reduces the revlimiter to 9,500 so that the engine is never 'accidently' thrashed, such as sticking in 1st gear or some similar, jsut a precaution!

When the bike is new, the blues are set low so that they illuminate at around 4/5,000 as you shouldn't go above this for the 1st 1,000 miles. You can then adjsut them to reflect your preferences.

 

Mine were also set low & I wondered what the hell they were mean't to be for. Then I found the relevant bit in the wee manual and adjusted them - don't hit the top one so much

 

I don't recall seeing my flashy blues since winter, now it is summer I guess I don't notice them.
But yeah, I think I reach that area of the rev's now and again where they would start getting excited.
