In the control handle. If you take off the switch cover you will see the wires that lead into it. Usually it will need to be soldoered to replace it.
Check your brake light switches. Chances are its the front one. The clip that holds the switch in place may have fallen out or the lever isn't hitting the switch.
Most likely cause is a problem with the front brake light switch located in the right switch housing on the handlebars. If you installed new levers you may have ones for a different model or the clip that holds the switch my have fallen out.
the front switch is inside the handlebar right controll, the side the lever is on. you have to take this apart to se it, 2 torx screws, the back switch is located i n the brake line on the line to the rear caliper.
Motorcycle Front Brakes versus Brake LightsI'm not familiar with your bike as I'm into "old" [1950 and prior years] Indian and Harley machines.On those older machines, only the REAR brake pedal was fitted with a brake light switch, and the FRONT brake [on the handlebar] did not have a brake light switch.I suspect that is why you have no brake light operation IF using ONLY the front brake.If you're handy with tools, and with a little imagination, you should be able to successfully install a brake light switch into the front brake system.
check the play in your rear brake lever, may be too tight and activating the brake light switch. or the front brake lever may be depressing the switch in the control housing. or you have a bad switch. or, when you rewired it, after installing that cool skull tail light, you got the running light wire and the brake light wire backwards.

The front is on the handle bar and the rear is on or in line with the brake peddle.
