You could use a voltage regulator or a series resistor to reduce the applied voltage to 24V. Or, with 48 volts DC you could just wire them in series so that they each get only 24 volts. The current (amps) will take care of itself (I=V/R), about 5 Amps, I'm told. **Q: Which prong is power and which is ground?** A: Does not matter..no polarity. **Q: Will this fit a 2016 subaru legacy? please only yes or no. no shoulds.** A: This isn't a yes/no question. It'll fit any car so long as you can find a proper place on the frame to mount them. Mine came with only one high-tone horn. I had to find a place to mount the second. Look at videos of others doing it. You may need to drill, and you'll need to run one wire only as the negative runs through the frame. **Q: why are there two ? can i just install one?** A: Some vehicles are outfitted with two of these, like my SUV. Yes, you could install just one, but I find myself wondering why you don't just by a single horn? ## Frequently Bought Together - HELLA 002768821 Black 92mm 24V Disc Horn Kit (Universal Fit) - VRWEARE Universal Motorcycle Electric Horns Waterproof Round Loud Speaker 12V 1.5A 105db small horn for Motorcycle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/263640779-3am-002-768-821-signal-horn-hella-heavy-duty-horn](https://www.desertcart.us/products/263640779-3am-002-768-821-signal-horn-hella-heavy-duty-horn) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-13*
