Activating dummy lights

[wheelbender6]

My Genuine Buddy has some lights in the front of the bodywork that are not powered. (they are required in some other countries where turn signals must be integrated into the body. My signals are mounted on the bars). There is a company that makes a wiring harness addition that will allow me to use my dummy lights but it costs $100. Couldn't I just splice into a hot wire and add a simple rocker switch to power the dummy lights? Anybody done that with there dummy lights?
