So an update: I raised an issue with PayPal who initially found in the favour of vendor.
I finally managed to speak with a human to whom I explained what had happened and that all I wanted was the lamps I’d paid for and ordered. They tried and failed with vendor for this to be understood so EVENTUALLY I got a refund and told to keep the wiring inc switch etc.
These are decent quality lights without the Denali price tag.
I’ve had a pair of these ( the same pair) on three of my bikes without issue , for ten years . Just keep swapping them from bike to bike..
LED so very low power drain.
Mine had fog light type lenses and were mainly intended as a DRL. They can be bought with spotlight type lenses.
