I have a truck on which the rear turn signals are not very visible when the parking lamps are on. So I am trying to get the parking lamps to turn off while the turn signal is on. Below is the wiring diagram that I am planning to use and I just need a professional confirmation that it will work. The bulb I am using draws 2.2 Amps. I have learnt from this forum that a regular auto relay which is 30A rated may be an overkill as the current draw of the coil is a couple amps. So I am planning to use this 10A PCB relay. https://www.e-sonic.com/product-detail/mode/505330.html?p=45319483
Will this work, and is the relay suitable? Also, I am assuming I do not need a flyback diode with this relay, correct?
Your input is greatly appreciated.
