What is the reason to buy another set of headlights? To put them on the shelf?
The cost of the kit will be about £250-270, but it includes everything (rings, 2 modules, buttons, cables, connectors, cutting tool, silicone glue). You will only need to have, borrow or buy some tools and go step by step through my detailed manual.
The labour time is 2 days to modify headlights (obviously car is undriveable), and another 2-3 evenings, when you will piece by piece finish the installation.
I don't know how "ultimate" it is, but there is (or will be in the nearest future) 15 cars with my rings (incl. one in UK)
I will post here some detailed informations about my kit soon.
Till end of the year I want to collect orders, then some deposits. Complete kits will be sent early spring 2013.
