I need to know what diode I need for a light set up I am working on.
The main current flow through the diode is going to be 9v going to power a 55watt roughly ??? amp bulb. There will be ocassional burts of 12 v power for when the light is flashing however I am going to wire up a seperate switched line to provide constant power to the same light on demand with 12 v power and wanted to keep that from back feeding up the line that supplies the 9v power.
Above is the schematic, I need help figuring out what diode I need to get so I do not fry the electrical systems in a 2012 sierra
