Default Help! Strange Tail Light Malfunction (video)

Well basically, my tail lights do not light up when I turn them on and also no brake lights..not even the license plate lights work...front headlights work, turn signals work, hazards work....but look what happens in the video when I step on the brake pedal...

Only thing i can think of is that a couple days ago I had an aftermarket head unit installed at a pretty decent audio shop...maybe cut a wrong wire?
I already checked the fuses and harness for the euro tails...all good

I had an electrical issue basically the same as yours a few months ago and it turned out to be a bad ground connection in the rear lighting wiring harness. See thread HERE
P.S. I also have the euro taillights.

A lot of times that indicates there might be a bad ground and the current goes thru the bulbs to get back to ground

Update....well the problem is back...no tail lights...licenses plate lights and rear side markers...all out again. So I unplugged the euro harness and plugged it back like stock...whaalaa...my lighats work now!!

So, the problem is with the euro harness or maybe even the stock one...thing is everything looks fine...so I just tried puahing all the wires into the connectors...maybe they came loose??

Check your wire under the dash on the drivers side, The one you had to cut for the euro harness.
