Yea, I think they're shorter and "wider.
I'd just go with something like an FX-R or a TL, unless you can get a really good deal on used Navi projectors. Those are pretty good bi-xenon projectors that should be better than the Navi ones.
As far as your friend, if they are in any way blue, the aren't 4300Ks. Hints of blue start at 6000K with really blue being 8000K and 10000K. Depending on the seller, 12000K/30000K can be either
very blue or pink. 3000K are yellow.
These are what mine look like. Hopefully the forum resizes correctly:
You can tell mine are plug and play from the hot spots in the center of the road. I don't mind them, and they work pretty well in rain or fog, but I do want to retrofit. Someone gave me a set of E55s, but I haven't had time to finish the retrofit. I might just break down and buy FX-Rs, since they should be a lot easier to retrofit.
