No idea on that kit but I wouldn’t go for 8k or 12k lights as they are too blue and you’ll look like a wannabe cop plus the bluer the light the less distance it throws onto the road.
6k would the max I’d for.
Sorry no advice on which kit, I’d had mine fitted ages ago.
12000k lights will be far from blue, more like purple, and there is a chance will be worse than stock.
Best option for best visibility/distance is 4300k, ,most stock cars have 5000-5600k (light blue’ish)
I was thinking of a similar kit for the Bonne’ to upgrade some running lights for night riding, let us know the pros and cons of your installation and some photos too
