Rear lights

IVA restricts the rear lights to minimum 350mm above the ground, max 1500mm and minimum horizontal distance to the fog lamp of 100mm.

Roll out the measuring stick again, I marked out a position more like 420mm high - where the lights sit virtually horizontal - i.e. not pointing up or down - on the wheel arch curve:

The easiest way to mark out the drill holes seemed to be a paper template created by pushing through into the holes on the lamp unit:

Then lots of double checking, measuring, spirit level etc before the holes & not forgetting to flip the internals on one lamp upside down so the brake and indicator bulbs are in the right places and change the default bullet connectors for spades while everything is easily accessible on the bench:

 I think we're ok... 

Consulting the GBS loom instruction sheet has the wiring layout for the plug, then it was just a case of wrapping everything up neatly and securing the cabling with P-clips on the lamp mounting bolts:

I'm all out of P-clips, so could only wire up the offside for now.

Perhaps I should shorten the loom from the lamp?
