Here is some more information to help trouble shoot. The bike fell over on to the right side when I was taking it off the center stand. The front brake lever broke and some minor scrapes on the exhaust pipes. I replace the lever. I didn't check to see if the lights worked properly until today. So, I uninstalled the brake lever and reinstalled. Brake light stays on. I have hyperlites installed so I removed those. Brake light stays on. Anything else I should check?

Thanks.

The brake light comes on via the front or rear microswitches. The front switch is located on the front side of the brake reservoir, down low. When the switch is in the normal position (brake light off) the brake lever has a tang built into it that depresses the button on the switch. When the brake lever is applied, the tang lifts off the switch and the brake light comes on. You can hear the switch click when it is operating correctly.

Either the switch is bad or the lever you added doesn't have the tang on it. You can physically test the brake light via the button on the switch.

I believe you are correct. I hear no clicking sound when I depress the front brake lever. I hear the clicking sound on the rear brake control.

I took the front brake lever off again and there is no tang or switch. See photo. Must have come off during the shuffle. I wonder if I have to replace the whole right right side controls or can I just get the brake switch?

Thanks tahtye for your help.

The switch is there but the Ďbuttoní that mechanically activates it is gone. Youíll obviously need a correct lever too.

Iíve read one needs to purchase the entire housing in order to get the switch. But, I think I remember somebody did find a switch that could be purchased separately. I donít have any part numbers though, sorry.

Here is a rear brake switch for my T120, itís a SPDT, #T2024932. Not sure if this could be made to work but it looks like it might.

If you don't want to buy the whole assembly just for the switch apparently this is the correct part.

Thanks for that... They don't ship to the USA.

I did find this on eBay...

Okay, I need some more help. I have the new switch installed and it works fine. That switch is very fragile. Anyway, I am trying to reinstall my Hyperlites. Like an idiot I didn't mark the location of the lights when I took them off. I am not sure of the wiring. I believe the Back is the ground and the Green/Red is brake light power.

Triumph
Black=Ground
Green/Red=
Green/White=
Green=
Yellow=

Hyperlites
Black=To Ground
Gray=To Running Light Power
Red=To Brake Light Power

Thanks for the help...

Hi again, What functions do your Hyperlights have? Or what functions are you trying to make work? Are they turn signals? Brake light?

Triumph
Black=Ground
Green/Red= left front + left rear turn signals
Green/White= right front + right rear turn signals
Green= try connecting this to the brake light
Yellow= try connecting this to the running light

Hyperlites
Black=To Ground
Gray=To Running Light Power
Red=To Brake Light Power
