⚠️ Installation & Safety Tips:

• Most universal horns require a relay if drawing more than 3–4 A—avoid wiring heavy horns directly through the stock horn button circuit ([turn0reddit14]citeturn0reddit14).

• Highly recommended to use a fused wiring harness with inline fuse and relay for safe high-current support.

• Loud horns like Denali SoundBomb (~110 dB) are popular upgrades—though they require a relay and consideration of potential startling effect ([turn0reddit15]citeturn0reddit15turn0reddit17).

• Some riders report over-the-top loud horns may inadvertently cause startled reactions—use sparingly and responsibly ([turn0reddit16]citeturn0reddit16).
