The bulbs are hi/lo headlight LEDs with Amber low beam and 6k white high beams.
I used a 5 pin relay to add the switchback function. The relay +VDC is connected to an ignition +, grounded to chassis, normally open to the amber, normally closed to the white, and the trigger wires to the turn signal +.
You'll need 1 relay per side.
