Hi Exdee
The angel eyes I have fitted them my self, just bought them on eBay and then when I had time removed the lights and did the installation. Took half day in total.
The perforated film, I will not lie it does recuce the output by about 10% ... but I do not know how bad it will be on halogen lights. Mine being the factory standard HID look fine.
And at the end of the day it is just a self adhesive film ... can be removed at any point and wipe off the glue residue with some cream :) :) only cost me £10 and I only used half the film.
Thanks for your reply. Your retrofit has given me hope, that some day I'll be brave enough to transform my headlights.
