Here we go, sorry bout the crap quality, only realised now i have a big smudge in the lens.
First we got the new and old...

Then I took some photos of pulling out the old but its simple. Open boot and on the black trim on the side of the tail light where the boot closes, undo the 2 plastic clip screw thingees, i needed long nose pliers to pull the top ones out, then put a cloth over the tip of a flat head screw driver and just gently prize apart the trim from the side of the light, it will pop out and then pull it out. It then exposes 2 metal screws that retain the light assembly. Once theyre undone, then sort of palm the outside of the light and pull it back out of its 2 locating lugs. Unscrew the bulb fittings and your done. When fitting these LEDs then just pull out the tail/stop bulb from its holder as these tail lights have a plug wired to them to go into the factory bulb holder.

This is where the old tail/stop bulb was. The LED harness plugs straight into this, then screws into the back of the new light assembly the same as if you were mounting a bulb

Just check by turning on your park lights when you plug them in, if you don't see anything, pull plug apart, rotate 180deg and re insert and should be fine

Custom test stand not included so you can check the difference between off/tails/stop. Yes they are definately bright enough. Alternatively you can jam something between front of drivers seat and brake pedal if you dont have access to a custom stand this elaborate

Mounting is reverse of removal obviously and this is the finished result.
Tails

Stopping

And finally a real crappy shot comparing the colour, you notice it most in the surrounds of the light, and stays dark in sunlight blending in a whole lot better on a black car. Need to get some of those mirrored globes though for indicators, or are there LEDs to plug into those too?

So im happy with my hong kong specials, they really look top notch, and i didnt have to split my light open to do the tinting and wait for it to dry (dig at sedan owners) Honestly once you sus out what your going to do undoing which screws etc, all up you'll knock this over in 15 minutes. Rated 1.5 out of 5 difficulty. The .5 cos you need to check if they work, if not, undo light harness and turn over re insert.
Cheers in advance, thanks for looking
