Interested in attending a Mini in 2020? Minis are typically held on a weekend during April-July. Watch the Mini Christmas Expos forum to receive alerts (and emails) when planning and discussion begins.
At US$45 for the 16 output leads plus US$13 for the dual input leads this would cost approx AUD$84, based on today's rates. On top of this would be shipping, which is generally based on weight, and I would suspect would be quite expensive.
Compare this to 16 x approx $3 for 3m power leads from your local discount store, 2 (plug ends) of which can also be used for your input leads and a couple of dollars for crimp lugs.
