Review: Working well for a good priced item!! - These horns are working out nicely on my wife’s ‘50 Chevy pickup. We’ll see how the plastic type housing holds up against time but the price was good and they fit and mounted nicely where I envisioned them going and they put out a good horn noise/sound too. So far I’m glad I bought them and for the price I recommend them and would purchase them again!!
Review: NOT A TRAIN HORN SOUND - The sound and decibel level is exactly the same as a factory horn. There is zero difference. I believe this to be 100% false advertising!,,

## Questions & Answers

**Q: How many amps do these horns use?**
A: Replace the stock ones, with these.
Nowhere near train level.
But at least now I have horns.

**Q: Can these horns be wired together in parallel circuit**
A: Yes.  That is a standard wiring configuration. Not in series, parallel is correct.

**Q: What's the amperage draw/load?**
A: Very low

**Q: End cover for luggage rack**
A: No.  These are "not so loud" horns, nothing to do with luggage racks.
