I made my own led lights shape,color,size..
It does help the engine a bit,
but it is sooo little that is just useless..
Don't leave me stop you!Do what you have in mind..
And for the taillights removal, just unscrew the two bolts that "shines" when you open the rear door/hatch and then grab the light and push it outwards from the car..
There's just 2 clip things that hold it in the front of the hull..
The left light push to left, the right to right..
I'm not sure that i explained it properly..
[color=#FF0000]Watch out because the clips are plastic!!!!![/color]
I'll try to find my old one and take some pictures for you to see what i have in mind..
