Price was right and I like the color. The visibility is great. I think the lifespan is short, but oh well.
Also I did have to take the frontend apart to get the lights back in, it wasn't trivial but there are videos out there
I’m not sure if you are in the US. But I immediately bought these : Philips - Diamond Vision H7 Halogen HID Bulbs (Pair) https://www.amazon.com/dp/B007JZKBVW/ref=cm_sw_r_cp_apip_xt8yeJM4U9DTr To someone help with the yellow ish look.
But it certainly increase my range in visibility as the light projects so much further ahead than stock. I didn’t care for the leather seats and or sun roof. And the auto shut off feature and such. I’m happy with the S now.
They're not necessarily blue, just very cool white with a tinge of maybe some turquoise color. In my opinion perform basically exactly as other bulbs if not actually make the road look clearer because of the whiter color. I have recently put these Philips Diamond Vision in and they look great. Though I live in a well lit city so I guess I haven't tested them in very dark areas yet.
Philips Diamond Vision H7s, $35 on Amazon, and they ROCK.
