may be a slightly different colour, as you can get anthing from 4300k up to 20000k i have 6000k in a mk1 i'll post a picture, i dont know what the renault part looks like, but with these you put the bulb in connect to the ballast, and find somewhere to locate the ballast, either cable tie somewhere or bolt them in.
You're not going to believe this, but i just got my car out of the garage for the first time in 2 days, one of the ballasts has failed and will not light the bulb. However Don't let this put you off this kit is over two years old and has been through 2 corsas and now only the Clio, was just like luck that they're all the same bulb fitment. As far as i'm aware pretty much ALL HID kits are the same, just some have been branded and the price wacked up, never had an issue with the kit before today.

HID Kit installed under bonnet.
HIDs Ignited, Mine are technically illegal as i'm not running projector lenses, but i believe the 172s have projector lenses?
