## Description

Nilight 5 PACK Waterproof Relay and Harness 40/30 AMP Heavy Duty 12 AWG Tinned Copper Wires 5-PIN SPDT 12V Automotive Relay and Harness Set

Review: Resolved my issues with an older Fisher plow install - Great 5 pack of relays and matching tails. I had old relays taped together running my Fisher plow lights. Weird light issues had me questioning these relays. These straightened out my concerns about cross wiring, and made the connections truly waterproof. Bam! Lights work correctly again.
Review: Excellent value and quality - This is awesome! I used it to turn my golf cart off and on since EZGO key's are a joke and they can be turned on with paper clip. Now I can use the fob to turn it off when I get off and won't worry about it getting stolen. Would buy again!

## Questions & Answers

**Q: Can I get 6 waterproof relays with sockets?  I need 2 each for 3 windows.**
A: No

**Q: will this work with 2010 hyundai santa fe passenger mirror relay?  I'm getting a clicking/ knocking sound from the passenger mirror**
A: the relay will not work for you, the relay is for horns, lights, plow equipment, or trailer brakes, the problem is , the internal   system in the mirror is warn out, you need a new mirror, and that's about two hundred usd, and your mirror is ten years old

**Q: Can this be used as a flasher?**
A: Maybe not a "flasher" since there is a steady blue light at the end where the magnetic adapter rip fits, bit it does light up there.

**Q: How many amps (at 12v) does the (+) switch pull to open the relay?**
A: Ohms law I=E/R 12V/80 Ohms = 150mA or 0.15 Amps
