## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice quality
*by F***N on 2 April 2024*

The good thing about it it have a built-in fuse which make life easier, and a relief of the wiring hassle. So far no issues with the relay.

### ⭐ Fix the images
*by D***A on 15 December 2023*

Carefull some misslabeling in one image that confuses common trigger wire and positive source. Ur relay will still work but you will be pulling power from wrong side. Best read the numbers on the relays and trace the wires
