A couple years ago, I bought a pair of GP Thunder 8500K for $16 + $5 shipping. They've served me well. The color output is much whiter than stock and more closely matches the HID xenons. They look great at night, dusk and dawn, but can look slightly washed out in full and direct sunlight. That’s why I'm debating about getting the Weisslicht LED's.
As far as inspections go, I've never had any problem. If you think about it, how could they give you a hassle? Angel eyes are just DRL's which are not required by law anyway. In my iDrive, and I suppose the OBC stalk as well, you can choose whether enable or disable the DRL's all together.
