I would assume they are the same kind of fitting as the twin headlamp kit I have on the toledo. There are a couple of bolts on top of the headlamp just under the bonnet.
Below the headlamp I think there are two more bolts to take out. This will require the bumper to be removed.
I am just going by memory here as it has been near two years since I changed my lights. I'm sure someone will correct me if I have forgotten something, lol.
Hope that helps
