I contacted Ed and he suggested using a D2H bulb. It ended up being a better option then the H7. The D2H has a better flange for mating up to the weird setup of the Ed's headlight. It's also a longer bulb, which puts the light further into the housing. All in all, it turned out pretty sweet. The dynamic turn signals are awesome!
Any updates on these lights? I'm on the fence. Looking at GOLF R 2018 look for my mk7.
I really like the look but the install intimidates me and I want to be sure I'll end up happy with the product.
