Review on Enhance Your Car's Aesthetics with ESUPPORT 12V Car Auto Green LED Light Momentary Speaker Horn Push Button Metal Toggle Switch 19mm Socket Plug by Kevin Barbon

A: It depends on how you want the light to work. I have a 12v wire for the horn but the wire to the horn does not. I also ran a wire from my navigation lights to plus and minus ground. which it illuminates when the light is on. If you want it to light up when the wire is pushed onto Nostephen Moos I reposted Steven's post which helped me figure out the wiring. THANK YOU SO MUCH!
