I have had these on the ZS for only about 2 months, they are in mint - as new - condition but im happy with the standard set so they are up for sale.
As is common for these lights they misted once, so i have sealed around the outside (not seen) and if you double up the foam seals it's fine, not done it again since i sorted it
They are cracking lights and easily changed on your car.
Cost over £100 new, im looking for £70 and can post anywhere for cheap,
PM me if you are interested.
