Good value, well made,
Nice packet of 12v 5-Pin automotive relays with attached pigtail connectors. Appear well made, well marked, good materials used and have built in mounting tabs which are a plus. Nice 30/40 Amp rated, comparable with most common 5-Pin 12V relays found on automotive accessory devices. Easy to install using the pigtail wiring instead of having to make individual connectors. The 5 pack is a good value for anyone adding accessories like lighting to a vehicle.

Great Value for the Money
I bought these as for a truck project, and thank goodness I bought the 5 pack. The wires are very good thickness, easy to understand schematics, and you can pull out the wires that aren't needed (3-4-5 PIN) to complete your project. I have connectted accenting lighting to LED Bars to this relay.
