^^^^ The light units are available and IIRC are around £10 each (although you would need to check that against the part numbers that i posted as i never bought any, you'll need to make up the wiring yourself as i don't think they are available as all im afraid. Easier to but the standard units and looms from Boldsport,
2 dr £25.18, 4 dr £40.93 both those prices are with the cheapest form of shipping.
I have bought items on 4-5 separate occasions from them in the past with no problems and usually receive the items within a week, even when using the cheapest form of shipping. As mentioned as their products are OEM but for the Far East market, for some reason they get all the trick bits as standard.
