"How to wire turn signals and brake lights into a single filament bulb?" is a question I often get. It is slightly tricky to do, but very doable with the help of some relays and a YouTube video. The key to making there whole thing work is understanding how a relay works, specifically pin 87A. That is the pin on the 5 pin Bosch style relay that allows this functionality to work. Hopefully this video helps you wire your tail lights and turn signals on your automotive project!
