continuecrushing not sure if this thread is still alive but,
I wired up my 4th light for the V to be alone and for the triangle to flash when braking (following the instructions from the video). However what happens is when I turn on my lights the triangle flashes and stays on without hitting the brakes, and the V does not light up at all. I'm not sure if this is a bad soldering job on my end (I did use a crappy older one), or if I fried one of the nodes.
Wondering if you have any input or advice. Thanks.
