Why do my lights get brighter when I rev the engine?
 
Perhaps the battery is on it's last legs? I have some heated grips on, but that's it.

Also, The top half of the brake lights are dimmer than the bottom half. They also get dimmer when the indicators are on. :confused:

Any help gratefully received as always... [-o<

I think it is a good thing, that's the test to see if the alternator and reg/rec are charging the battery.

Which year do you have?

I believe that pre-k5 (or k6) pointies have a problem with the Rear light unit......

Yes, my K4 had a dodgy rear light unit. It was very subtle (possibly would of passed an MOT even), but one of those things that once you noticed, couldn't help seeing. A replacement unit fixed the problem.

Ok, I'm guessing a search will help here...?

Was that the only reason you replaced it? Was it expensive?

Thanks!

It's not a good thing. the regulator does exactly that, regulates the voltage. If your lights get brighter with the throttle then it's on its way out and will probably take the battery with it.

Really?! Everybike I've ever owned has done this. :confused:

It's a sign from god that you are the new messiah. You should form your own cult religion based on nudity and free love.
