Taillight bulbs, confused about how they work Options

[RoadRage]

Today I was fiddling with the car and I took one of my tail lights out and noticed there is a second brake and light bulb in the casing, and I never saw it work, I thought maybe it was meant to, so I replaced the bulb but it still was not working, So im writing to ask whats the go?

After doing some research (Looking at some pics on this forum) I saw that the OEM tail lights seem to have only 1 light working on each side, but the JDM tails have 2 brake lights.

Im hoping to get some JDM tails soon, but until then, I want to roll with 2 lights working, because it seems like a wasted light if its un-used and in my opinion two looks cooler,

I had a play and switched around where the light goes but for now im just left with the decision about which way should my lights work for now until I figure out how to get both to work



Was the inside bulb (the right tail light in the photo, that I switched) never meant to work and it was always meant to be 1 light only (left light) or do I need some wiring harness of some sort?

Ok cool, I thinks it the angle of the photo but both lights are lit up the same voltage. Your set up of when lights are on only the outside is lit but when you brake all come on is good, but I don't know how I would do that set up, but I think I'll spice the wire and add it so all lights are on when headlights are on,

But does that mean every person who bought jdm tails and has 2 lights on each side had to spice new wire? Even tho there's one useless bulb there
