Technical Tip for Electric Golf Carts (36/48-Volt Systems)
All electrical accessories such as headlights, taillights, fans, and audio equipment require a 12-volt input. For 36/48-volt electric carts, it’s crucial to use a voltage converter to reduce the entire battery pack voltage to 12 volts. This prevents damage to individual batteries and extends the overall life of your battery pack.
Recommended Voltage Converters:
- For Single Accessory: 13-084 (*sold separately)
- For Multiple Accessories: 13-030 / 13-034 (*sold separately)

Super easy install. This 12-volt horn kit came with everything—wiring harness, button, fuse, and clear instructions. Loud enough to get attention on my golf cart. Universal fit worked great!
Jacob T. –
Installed this horn kit on my UTV in under 30 minutes. Wiring harness made it easy. The horn is decently loud, maybe not for highway use, but great for trails and neighborhoods.
Kate D. –
Great value! The universal fit worked perfectly on my Club Car Precedent. Harness plugs were snug and the horn has a crisp sound—not too high-pitched. Fast shipping too.

Does anyone know if this horn kit works with a 36V system using a 12V reducer? The quality looks good, but I haven’t wired it up yet. Just want to avoid frying it.

Perfect universal horn for small vehicles. I put it on my golf cart—great volume, and the push button fits perfectly on the dash. Definitely a safety must-have.
Mark N. –
This complete 12V horn kit was a breeze to install on my ATV. Loud enough for street and off-road use. Would’ve given 5 stars if the wires were a few inches longer.

Solid little horn with everything included. Prime Golf Parts had the best price and fast delivery. Fit my EZGO cart no problem. Wiring diagram was simple and clear.
