I have an automotive light I want to be able to activate by 2 different signals.

Lets say it is a blinker.

I want to be able to activate the blinker via the normal blinker switch in the vehicle's cab.

But I also want to light the blinker via a bluetooth trigger device as well.

Example: Normal use of blinker, and, at a car show, light the blinker solid via my phone.

Seems I need something 2 input and single output that wont mix the input signals.

Cut lead to blinker light(+) wire and add an SPDT relay as follows:

#30 to blinker light side(+)

#87a to blinker light switch side(+)

#87 to 12V+

#86 to ground

#85 to (+) Bluetooth trigger

If you have a negative Bluetooth trigger, connect (-) trigger to #86, and 12V+ to #85.
