Hi Ben
I am probably talking complete nonsense, I certainly have no first hand experience with this sort of thing, but I would imagine that changing the wiring, such that the sidelights are not permanently on with ignition, constitutes a modification from the manufacturers standard. If that is the case then, as I understand it, it must be declared to your Motorcar Insurers. The question is whether this mod would be deemed to make the car less visible to other road users and therefore slightly less safe. If so would that result in an increase in your insurance premium or worst still nullify your cover. I think, if it was me, I would contact the Insurers and ask before I carried out the mod.
Regards Tony
