    I've been using these for years. They work great. From polarity switching to ignition coil power up, they are great.

    I have used hundreds of these relays for the custom relay systems I fabricate for classic VW's. After more than 3 years of use I have never had a failed relay. Highly recommended for any dry location use in 12V applications.

  • "High quality and unbeatable value!" by garyfish on 2/26/2010

    Quality:

    I'd been looking for a reliable source for 12-VDC relays to use in a variety of electrical upgrading projects for my car -- e.g., installing fog lights, and re-wiring my headlights with heavier-gauge wires to accommodate brighter bulbs. These inexpensive but excellent-quality relays were just the ticket! They're about a quarter the cost of comparable relays on eBay and other discount outlets. And MCM also carries high-quality and very affordable relay sockets that are compatible with these relays. Thanks MCM!
