Glad to know its not just me. The paddock ones look identical to the Amazon ones tbh, I nearly got those instead, just was in a hurry and nobody at home and Amazon delivery is easier to manage than DPD, royal mail, etc in those circumstances.Turned out to be a nightmare as there were some parts missing and an Amazon drop ship, so getting the right parts was a pain to say the least going round in circles with Amazon: (we will give you a refund er...they are fitted; we still give you refund; er no, I have spent hours installing and would have to do more to uninstall, just send the missing part; we authorise refund; no.... Amazon even rejected a negative review as it was not a fair review ????).
Moral of story: get from Paddocks!. On that note, have you asked paddocks???
On MOT note - Do they test a tow bar in an MOT? Just remove the bulb / trailer fuse for MOT???
