pulluptothebumper do coloured sensors but unless you get the perfect match they look naff. Do what I Did and get the black (cheaper), sand to take off clear coat and mount them onto a piece of very stiff card and spray the correct colour. I bought my paint from
www.auto-paint.co.uk in St.Helens. They were drying whilst i got the bumper off drilled the holes, mounted the sensors wired thro the existing hole, replaced bumper, pluged in sensors in sequence, pwered from the reversing light wire, buzzer placed behind rear seat, job done.

I'll put a photo on tomorrow, dark out there now
