The ST/RS Xenon headlights use
2004-2007 Osram D2S bulbs dipped
2008-2011 Osram D1S bulbs both dipped and main
These work as both dipped and main beam as they are BiXenon, meaning there is a shield in the projector that lowers when the main beam is required
Mine are all leatherette mate. You don't need to take off any of the plastic trim pieces to fit the covers, the headrest ajuster/button things the material just pushes underneath them. I did remove the trim around the height adjuster to see if there was any more room for the material, but there wasn't any need really as like the headrest adjuster, the material just pushes under the trim and doesn't need to go too far under. The hardest part to do is getting the elastic loops for the metal hooks down under the front seats, but if you or someone who can help has small hands its not too hard.
Just email them for a quote on your chosen colours/range, think the guy I spoke with is call Lucio. He said the covers are made in Italy but they still had a very reasonable delivery time considering they are made to order. Just mention I recommended you if some more people decide to get these covers I could talk to him about an owners club discount.
I had a problem with mine as they had put a lumbar support lever hole on the passenger seat where there was no lever, but they sent out a new upper seat section free of charge with quick delivery. I would defiantly use them again
They are relatively easy to fit, but as they are car specific they can be tight. They took me a few hours to fit properly and make sure all the creases were out. The rear backrests just Velcro to the rear of the seat, the seat sections are attached with metal hooks to the underside of the seat frame. The front backrests Velcro at the bottom but can be tricky to get the material between the backrest and the lower seat. All in all I think they were worth the money.
Mine were the Tiffany range, came to £250 with the white inserts and white contrasting stitching. Yes mine are the black and white ones, if you do decide to get some I can always post some pics of how they are fitted
No they should come with a loom for all the bulbs. The loom is joined together with the LED wires, there is no connector for the LED that is seperate. Maybe the ones you have are modified in some way, any chance of some pictures
