My tail light just has a single, 2 filament bulb. No festoon bulbs or whatever.
Brake switch is a "shutter".
My question is: does it matter where I connect each wire? Both tabs on the switch do the same thing as each other and both filaments on the bulb do the same thing as each other, no? Seems simple enough - I just don't want to eff it up.
(Ground wires are already connected out of shot in tail light photo below)

One of the filaments should be brighter than the other and the little round lugs on the sides of the bulb should be offset not aligned like a single element bulb.
The yellow wire 1 should come from the bar switch and is the tailor function.
The grey wire 2 should be from the rear brake light switch.
I would check the continuity with a meter from the switches to the rear wires.
Also if you have the correct voltage battery test the wires coming from the bulb socket to see which one lights the bulb brighter.

Thank you - so grey to the brighter, yeah?

That light looks like some aftermarket super cheesy funkiness.

Barn fix. The festoon holders are still there.

Still waiting to hear which "tab" gets which wire on a shutter type switch? Please.

I'm going to venture that it doesn't matter which side gets which wire. Just two wires and one is the ground. Just make a good connection on each side.

Yeah that's what I figured too but I thought that about the bulb too until this thread and then I started looking at the switch and how it functions and thought about the bulb and my brain just, well, farted. This shit isn't very googlable and Youchoob is fuck-all help too- I get close but just not close enough.

I'm not sure I'm totally happy with your "I'm going to venture" at the beginning of your post Razz emoticon , but if nobody disputes you then that's the direction I'll head.

+1 ^This. It doesn't matter. It closes the circuit to make continuity on a shutter-type switch.
