Hey all I am currently creating a custom rain light for my car (Light on rear bumper that flashes 5 times then holds when brakes are pressed). At the moment the rain light has positive and negative connected straight onto the + and - of a brake light globe wiring. However it being super bright and only wanting it to really be used in rainy or reduced visibility I wanted a way to be able to turn it on and off with the rear fog light switch in my car. The rear fog light also has only a + and - going to it. How am I able to have it so if the rear fog light switch is off pressing the brakes does not light up the rain light but when the rear fog light switch is turned on it then will flash when brake pedal is pressed. I'm not sure how to really go about this as wiring up something like this is completely new to me and I'm not sure if its really even possible or not.
