High & Low Note Horns for Tesla Model 3 | 1486943-00-A

1. Key Specifications & Compatibility

2. Why This Brand-Grade Dual-Tone Horn Is Critical for Your Model 3

1. Ensures Visibility to Others: The dual-tone (510Hz high + 410Hz low) sound cuts through traffic noise (e.g., highway speeds, busy intersections) better than single-tone horns, making other drivers/pedestrians aware of your presence to avoid collisions.
2. Meets Safety Standards: The 115–120dB sound level and frequency range comply with global automotive regulations (e.g., FMVSS in the US, ECE in Europe), ensuring you won’t face legal issues from an underperforming or overly loud horn.
3. Withstands Harsh Conditions: IP65 protection means it works in rain, snow, or after high-pressure car washes—no rust, short-circuiting, or sound distortion from moisture (a common issue with cheap generic horns).

3. What It Actually Does (No Tech Jargon)

• Delivers Clear Dual-Tone Sound: When you press the horn button on the steering wheel, both horns activate together—producing a loud, balanced “honk” that’s easy to distinguish from other vehicles (no faint beeping or scratchy noise).
• Works in All Weather: Rain, snow, or road salt won’t damage it—you can use the horn confidently even in heavy downpours or after a winter drive.
• Easy to Install: The included brackets match the factory spots in your Model 3’s front bumper, so you don’t have to drill new holes or modify the bumper.
• Long-Lasting Performance: The electromagnetic core and stainless steel hardware resist wear—no rust on brackets, no motor burnout from frequent use (e.g., daily commutes in busy areas).

4. Signs Yours Needs Replacement

• No Sound at All: Pressing the horn button yields no noise (even if the fuse is intact).
• Weak or Faint Tone: The horn sounds quiet, scratchy, or distorted—unable to cut through traffic noise.
• Intermittent Function: The horn works sometimes but not others (a sign of worn electrical connections or a failing horn motor).
• Single-Tone Only: One of the two horns (high or low note) stops working, leaving a flat, less effective sound.
• Rust or Damage: Visible rust on the original horn housing or brackets (signals water damage, which will soon cause complete failure).

5. Why This Brand-Grade Horn Outperforms Generic Alternatives

• True Dual-Tone Performance: Generic horns often claim “dual-tone” but only produce a single frequency (or uneven sound). This set’s 510Hz/410Hz combination matches the original Model 3 horn’s tone exactly.
• Durable Materials: Stainless steel brackets resist rust (generic brackets use cheap steel that rusts in 6–12 months), and the IP65 housing avoids short-circuiting (generic horns often have IP44 or no protection, failing after rain).
• Perfect Fit: Mounts to the factory spots in the front bumper—no forcing brackets, trimming the bumper, or zip-tying horns in place (a common workaround with ill-fitting generics).
• Consistent Sound: The electromagnetic motor maintains steady volume and tone over time (generic horns fade or distort after a few months of use).

• 1x High-Note Horn + 1x Low-Note Horn (1486943-00-A set)
