bpw Well... since its been revived. I did get it, my voltage regulator was fried and it messed up some wiring just below it. Replaced the regulator and the rear harness now they work like a charm.

Still cant get my F'n fan to auto kick on though I just flip a switch when Im at a red light. Would be cooler (lol) to not have to.

bpw I'll chime in since the OP is all good. I'm horrible at wiring chasing down issues ect but I'm a quick learner. My brake lights don't work either. Running lights yes blinkers yes no brake light front or rear. It's not the bulbs and it's not the switches I used the front switch to wire up a LED brake light bar that I mouted on my plate and that works. I got so frustrated trying to find it I bypassed it... I would like for them to work.

Glad you got it.

My credentials are invalid.

canuck Yes brake lever not engaging the switch pin. As both filiments in the brake bulbs were lit and all running lights operational.

My levers are chrome and are adjustable . Are these aftermarket or stock

jondog9 Cool, you seem to have got it.
So it was switch related, just that your lever wasn't releasing far enough to let the switch turn off? Which kept the brake lights on, like Wibbly suggested?

canuck First off thanks for all the help. The problem was the front brake lever would not fully open once the brake was applied. I'm hoping that the Lever just needs to be lubricated and I will also replace the brake fluid as it is quite dark maybe that will allow a little more feedback from the lever and allow the lever to go back to its original position thus allowing the pin to be fully depressed deactivating the brake light on.
Its just a little nudge out to get the lever to engage the pin.

So a lube and fluid change should rectify the leveres ability to pop back open. Will confirm

you clearly did very poorly in reading comprehension my friend.

Wibbly why is mr. gimmie talking about signals? the op is clearly talking about the brake light. the "running lights" he mentions is the natural state of the tail light, the second filaments clearly aren't lighting.

first just check the bulbs, maybe the brake filament is broken in both, though I doubt it.

what I actually suspect is that one of your switches is closed and you aren't seeing your running lights, you're seeing your brake lights.

unplug one of the connectors at the front brake and see if the lights dim, if they don't, check that the rear brake light switch is working properly, it could have malfunctioned. you could just unplug it to see.

if the running lights are working, then there isn't a ground issue, as both the brake light and running light share a common ground.

You will have PWR to the switch.

What needs to happen is to chase continuity through the harness on the ground side of the rear brake light switch to the bulb as well. Green with a stripe. I'll post photos of the CBR600 I fixed soon. Big you can work a meter and know how to validate continuity along a wire buried in the loom you will be ok. If not best to see my photos, call me, or take it to a solid mechanic.

OP didn't say the rear blinkers were lit. He said the rear running lights were working. Which is normal if the turn signals are stock. Are you assuming the turn signals are integrated and lit? He didn't state if he has stock rear signals or integrated into the rear brake lamp.
Anyway, I don't see what that has to do with the front (or rear) brake switch.
Or the bulbs.
It's a long shot but both bulbs could have broken brake filaments at the same time. Possible, but not probable.
Assuming both bulbs check out, a quick two minute test will eliminate the switch as a problem.

I did say I thought you were right about wiring, specifically a ground.
It just made sense to me _a random member on a forum_ to chime in with a different approach.
To the same end.

Lets see what pans out...
