Headlight bulbs needed - recommendations/tips

[moltuae]

I think you probably made a good choice regardless. I suspect the Gen2 improvements (over Gen1) are negligible and not as great as the marketing spiel would have us believe. I think both will show similar improvements over standard. I actually bought a pair of Gen1 bulbs first but I haven't fitted them. When I discovered the Gen2s were out I decided to buy those too and keep the Gen1s as a spare set.

You're probably already aware of this, but just make sure the bulbs you have are genuine; there are a lot of fakes, especially Gen1s (probably just because the Gen2s haven't been around very long yet). As I understand it, some of the fakes are far inferior and can radiate a lot of UV which can damage the plastic headlight lenses. The first pair I received were fakes. At first glance they looked genuine but the giveaway was that the authenticity labels were identical and had the same number; comparing other fake characteristics online (in particular the lack of welding) confirmed they were fake. The seller pleaded ignorance (blaming his supplier) but replaced them with a genuine pair. The labels on the genuine pair were unique and the holographic part was much more noticeable.
