Welcome to the club Brett,
I put a poiler on mine with the integral breaklight. The cost was £280, plus spraying, about £65 for paint and fitting about 1-2 hours (about £65 an hour). I got a discount through being a gold member and fitted it myself. Quite an easy job but worth taking your time over. It cost me in total about £250. There is a link at the top of the page for Quanan parking sensors, deffinately worth a look...
