When you changed the front brake light switch, did you check to see if the brake light was on while the wires were disconnected before you soldered the new switch in? Disconnected from front and rear bake switches.
Are you "sure" that the brake light is on and not just the tail light? A quick test with the front brake switch button fully pressed in. With the key on so the lights are on, take a jumper wire and go between the two wires that go to the rear brake light switch. That "should" make the brake light come on.
If this has an incandescent bulb, you should be able to look at the bulb and see if both filaments are lit or just one. Not sure what you will see if it's LED. Different LED's do the brake light differently.

Since your "SURE" the brake light is on and not just the tail light.
You might try removing your front brake lever CAREFULLY and with the rear brake light switch wires disconnected. Turn the key on and push the front brake light switch button in with your finger or a suitable substitute. That should turn off the brake light. If it does, then an adjustment would be needed, re-read the previous posts for that.
If it does not go out??? I do not know how the brake light is controlled. BCM, ECM TSSM??? That could also be the issue????
Do you have some sort of aftermarket brake/tail light control device? One of those that flashes the brake light or the like? I have one that makes my turn signals tail and brake. If that device on my bike failed, maybe it could keep the brake light on???? Not sure what would happen.

I justs went out to the garage to check a few things before heading of to work for the night shift and it appears my battery is now dead. I always keep it on the trickle charger when it sit for long periods but I think the charger actually dis charged the battery. I've been suspicious of it lately.The " Charging" light never seems to go out even after a long period. I have another in the basement so I have it charging now. Will check in the morning. Will perform more tests when I have some time through the week. Seems like it's one thing after another. Between my truck/car/ and bike I'm always trying to fix something.

Just on my way to the store see if I can match up a rear brake light bulb for this 2006 heritage softail classic. And I just remembered I need a new bleeder valve for the front caliper. Rather than go back home does anybody know the proper thread size and wrench size for replacement bleeder nipple for this bike?
