Just in case anyone is unfortunate enough to need replacement lights.....
Mine being the last 4thirty kit expected to be sold in the UK, the part numbers on my lights appear different to those I've seen mentioned on the forum; Ten Pin's rear light wiring details [which were a huge help - thanks TP] stated the rear lights:
Left to right they are:
157516 157514 -------- 157513 157515
The two outer lamps 157516 and 157515 are wired the same, as are the two inner ones.
Using the superseal connectors pin nos
Lamp pin # function wire colour
157514 4 common white/black stripe
& 3 reverse red/blue stripe
157513 2 not used
1 Fog yellow
157515 4 common white/black stripe
& 3 side green (thin)
157516 2 indicator green/black stripe
1 brake green (thick)
My lights are:
Outer - 185670 and 185671
Inner - 185668 and 185669
On the inners 185668 and 185669, there is a minor wiring configuration needed:
Pin 4 = common = white/black stripe - as previous
Pin 3 was reverse red/blue stripe, my light part numbers = not used
Pin 2 was not used, my light part numbers = reverse = should be red/blue stripe
Pin 1 = Fog = yellow - as previous
