I was hoping someone here may be able to offer me a little advice (I've done a search and can't find anything related).
I purchased 4 identical outdoor lights which I wired up about 6 months ago - all was well until in the past couple of weeks one has stopped working. On further investigation, it has been letting in water and essentially short circuited itself, irreparable damaging it.
The only issue is that they are no longer stocked (or indeed manufactured, from what I can tell), so for them to match as they originally did I would need to replace all 4.
What are my rights with regard to returning all of them?
Obviously it shouldn't be an issue getting a refund for the broken one, but the others will be well outside of the returns period for the retailer and I can see them refusing to take them back, especially as they are used, not current stock, and without the box (although with receipt).
Any help would be greatly appreciated!
