JD1912 Fused On/Off 4-Pin Car Relay 12V 30A Normally Open Contacts 30 Amp Car Bike Van

5 stars rating for sheerness and warmth!? It's a relay? So swap sheerness for conductivity and warmth for effectiveness and that's what I gave it 5 stars for. Reliability is probably what you're really wanting to know? Won't know for a while though. Could hazard a guess about where it was made because if it was local it would be twice the price? Anyway, doesn't matter and some of the stuff coming in from far away is pretty good now despite what Mr Trump says.

Added a reversing camera so had to replace my old relay, worked great

Used to replace duff rear window demister relay on Ford Capri - I needed one with a built-in fuse and it's done the job very well. Delivery good, all well, thank you.

Saves having a separate in line fuse when doing wiring on my car, works perfectly

As described,saved lots of time,

Fantastic used with an led light bar to wire directly into high beam

Works perfectly for what I needed it for.

I bought this relay because of the built in fuse. This meant I did not have to add a fuse in line. However the disappointment was that the fuse was not held very firmly and simply fell out there by breaking the circuit. It was therefore necessary to hold the fuse in position with insulation tape. Not the neatest of solutions but it did solve the problem.
