LOL! Not surprising response. It's not "dinan stage 3" badge. It's just a Dinan3 badge. I like my warranty since I beat the car pretty hard on tracking days. You are right, it's pretty pricy. But if I can burn my $$, then why not? I'll probably lose more investing in the stock market.
I figured I am paying 20% more if I were to piece the kit together using similar parts. That said, I am also paying for the R&D time of the setup. You could say the same thing abut Alpina, Stasis, etc.. But they all exist and are profitable because people respect the products.
WRT LEDs, I have shitty Bimmian ones right now. One time, a cop stopped me for not having DRL. That's how dim they are. Hence the upgrade. It's Lux V4 btw.

I don't think I will be able to stand any other color but white for normal use. That said, being able to go blue could be cool for fun every now and then.
