Parts diagram, teardown or others for Gen 5?

Xグレード センターテール1文字化(Z化)（トヨタ プリウス・60系）by りぐっち@カロッツェリア信徒 - みんカラ

I found my own answer, if I'm translating step 10-13, the bulbs are in the plastic lens trim itself. No wonder I couldn't see where they go from the back of the trunk alone. It seems different versions have the light hole plugged.

In step 13 you see the little sticker I mentioned that was behind the plastic boot with the yellow tape on it.

I'm using an online translator so if someone speaks Japanese and can chime in, feel free.

Otherwise it looks like to accomplish this on an LE/SE, you will need a new centre lens piece, 2 bulbs and a harness. Basically not cheap.

 

Apparently not. If someone wants to try on their North American SE, I'd be curious to know. I do think Hammersmith mentioned there's different part numbers.

It also looks like it could be popped out and maybe be able to add the LED. Reflectors might be different and I think they are. I'm afraid of breaking the plastic trim on mine checking as it seems pretty brittle.
