Some of my tail light leds are out, I've tried searching for a solution but I don't think any of the posts had a solution from what I found. Is there a solution to fixing that problem? Or is soldering leds and universal LED strips the only solution? Aside from buying a new spoiler etc. Any inputs would be nice.

 

Yes, replacing the busted LED or replacing it with a new LED strip would be the only solution. I advise replacing with a whole new set of LEDs just so they light the same brightness and they have waterproof ones too which can prolong its life.
