There are plenty of plastic body clips available. I'd remove one, measure it, and then look for one matching the dimensions on Amazon or ebay.
I got them on Amazon. They aren’t cheap otherwise they are probably fake. Once you get them use osrams site to verify authenticity.
Both are in and I went for a night drive. I don’t like them. They have a yellow tint as opposed to the white color of stock lights. Visibility doesn’t seem much better. I really want a bright white light!
That's a bummer, but good feedback. On the (slight) upside, a more yellow bulb will provide better visibility in the rain/wet, but I am surprised they were more yellow than stock. Are you sure the car had the original bulbs, or did the PO replace them at some point?
I just ordered a pair of the Lasers from hidconcept.com. A pair was ~$174.25 shipped with the promo code listed on their page. No affiliation - just seems to be the best price right now from a reputable seller.
