Can 1600 be adapted? I know they drop down a bit lower but 
wonder if the angles are the same and would they be easier to get?
 
 
They look similar to the later models with reverse lights
 
I'm in the same position as you unfortunately and the my wagon is meant to go the shop for paint and panel next week. I still don't know what I am going to do for rear lights

Cheers mate.
 
What's the difference? Has it got the reverse light?
 
Because if you're intrested in selling them, I'm willing to modify my wagon to suit. I just don't know what else to do necause it's meant to go for panel and paint next week

I think we should get some made up from somewhere, do a group buy. Mine are in perfect condition, really glossy not faded but they are brittle and slight hairline cracks when i undid a screw one time. 
 
I would buy like 5 sets just for the rest of my life with my wagon haha

There are some good companies in Taiwan and Thailand that can do them but lost their contacts
You can try Alibaba.com and search

There use to be several mobs that did minimum 10 order but all gone, I just checked also
but you can use the readily available diy kits, finicky but with patience they work.
Easier than painting a car of course but the same kind of attention to details required

I'm keen to give it a go also.
 
I will ask a few place first to see if they are interested in making up a batch but failing that, I'll be giving it a go
