I bought exactly the same items for my c32, clear lens bi-x.
£450.00 PLUS £25.00 P+P
One thing you need to know though, in order to exchange the lights the front bumper must be taken off as some of the screws are attached underneath it. I took the liberty in re spraying the bumper whilst it was off "as i had a few too many stone chips for my liking" from a decent sprayer.
Cost £250.00 all in, inc exchanging the h/lamps.
Going in on Monday finished by Wednesday afternoon.
Ill post some pics when its done if you'de like.
