Brake light won't shut off

I have a 2009 fireblade and replaced the taillight (oem) and levers. I crashed the bike which is the reason I needed these items. I don't know 100% that the brake light was functioning properly after the crash but I noticed it as soon as the new levers were on, hard to miss the bright red light being on as soon as you turn the key. I disconnected the rear brake line and it did nothing. If you take the front brake lever off, it stays on. I took the plunger out and pressed on the bowl, it has compression in and out. I can get rear brake sensor $30 new or $10 used but I'm pretty sure it worked before switching the lever. Any suggestions?

With the front brake lever off, if you manually depress the brake light switch does it go off?

......nothing will get the light to go off. I took the plunger out and pressed on the bowl it sets into cut the light stays on.

Maybe you wired the brake light to the running light, so when the bike is on instead of the dimmer light being lit it is lighting the brighter brake light portion in the taillight.

I just unplugged the old and plugged in the new one, no wires. Also...I noticed it after changing levers but before switching taillight. The damaged taillight was stuck on as well.

One thing to add. I unhooked the two wires that go to the front switch and it shut off the brake light, running light still on. I was hoping the back brake pedal would engage the brake light but no luck.

So it's your front brake switch, correct?

2017 Fireblade

I was hoping not, its $200. I don't understand why the back brake pedal won't trigger it. Aggravation is going to lead me to waste money buying both switches....uuuugghh
