I thought about this too but need to identify where the fault is otherwise could end up with the same issue. My garage is £50.00 an hour labour costs if it has to go in.I had a similar issue with a different model Thule. In the end, I decided the cheapest fix was to buy a trailer light bar on ebay and lash this over the top of the original light set with cable ties. Works fine and much cheaper than the £90 replacement part or garage repair, I thought.
