Manufacturer

Hella

<p>Founded in 1899 by Sally Windmüller in North Rhine-Westphalia, Germany, Hella has evolved from a manufacturer of acetylene lamps into one of the world's most respected automotive lighting and electronics specialists. The brand name likely honors Windmüller's wife Helene, whose nickname was Hella, while also evoking the German word "heller" (brighter)—a fitting tribute for a company that has illuminated the road ahead for more than 125 years.</p><h3>Innovation in Automotive Lighting Technology</h3><p>Hella has been known for its innovations throughout its years, and plays a major role in bringing new features into lighting systems. The company's pioneering spirit is evident in its history of firsts: in 1971, Hella became the first company to get the go-ahead to build a halogen light, and in 1992, Hella started manufacturing the first-generation Xenon headlights. More recently, the company introduced the world's first full-LED headlamp system in 2007.</p><p>Today, Hella develops and manufactures headlamps, rear combination lamps, signal and interior lights for almost all renowned automotive companies, ranking among the top 5 suppliers worldwide. Their <a href="/312-hella-headlight-assembly-10762">headlight assemblies</a> and <a href="/312-hella-headlight-2796">headlights</a> incorporate cutting-edge technologies including matrix LED systems, adaptive lighting that adjusts to road conditions, and high-definition illumination that projects safety information directly onto the roadway.</p><h3>Electronic Components and Safety Systems</h3><p>Beyond lighting, Hella is primarily engaged in the development and production of high-performance lighting technology and vehicle electronics, with major products including headlamps, rear combination lamps, sensors, actuators, and energy management systems. The company's expertise extends to <a href="/312-hella-hazard-warning-and-turn-signal-flasher-10461">hazard warning and turn signal flashers</a>, which incorporate fully electronic control systems for reliable operation.</p><p>Hella also manufactures special signalling for official emergency vehicles, including flash beacons and beacons in blue and yellow, Visual Warning Systems, and all-around sound combinations. These specialized products demonstrate the breadth of Hella's engineering capabilities across both civilian and professional vehicle applications.</p><h3>Global Reach, German Precision</h3><p>Hella has more than 100 locations in over 35 countries and operates in the economic regions of Europe, NAFTA/South America, Africa, and Asia/Pacific. Despite this global footprint, the company maintains its commitment to German engineering standards and rigorous quality control. When you select original parts with the Hella label, functional safety, a perfect fit, and product durability are guaranteed—that's Hella Original Parts Quality.</p><p>For specialized applications, Hella's product range extends to <a href="/312-hella-light-bar-1069">light bars</a> for off-road and commercial use, as well as <a href="/312-hella-mastheadall-around-lights-with-fixed-mount-200665">marine navigation lights</a> through their Hella Marine division. Hella marine is a globally recognised leader in LED manufacturing and design, renowned for offering complete piece of mind and enduring safety at sea.</p><h3>Aftermarket Excellence</h3><p>Hella is the undisputed top-ranked supplier of vehicle-specific lights in the independent aftermarket, with almost 70 percent market coverage in Germany and 50 percent in the rest of Europe. This extensive catalog ensures that vehicle owners and repair professionals can source authentic Hella components for virtually any make and model. The company's aftermarket parts maintain the same exacting standards as their original equipment, manufactured in the same facilities using identical production lines and testing procedures.</p><p>Whether you're restoring classic vehicle lighting, upgrading to modern LED technology, or replacing failed components with factory-quality parts, Hella's combination of pioneering innovation and proven reliability makes them a trusted choice for automotive lighting and electronics.</p>

Product Details

The Hella 012010821 is a high-performance dual-tone horn kit designed to deliver superior sound output for automotive, marine, and powersports applications. This universal 12-volt horn system produces an attention-commanding 110 decibels, significantly louder than most factory horns.

Key Features:

  • Dual-tone design with one 500 Hz high-tone horn and one 400 Hz low-tone horn for rich, attention-getting sound
  • Powerful 110 decibel output ensures you'll be heard in any situation
  • Compact 3.2-inch trumpet design fits most mounting locations
  • Durable yellow ABS plastic housing resists weather and vibration
  • 72-watt power draw on 12-volt systems
  • Includes galvanized metal mounting bracket for secure installation
  • Universal fitment for cars, trucks, motorcycles, boats, and RVs

The complementary frequencies of the high and low-tone horns create a distinctive sound that cuts through traffic noise more effectively than single-tone horns. The weather-resistant construction and corrosion-resistant bracket ensure reliable performance in all conditions. Complete kit includes both horns and mounting hardware for straightforward installation.

Great price but had to search several times to find the product and your company

I believe the shopping experience so far is good, but adding sedan or coupe is ideal to car choices. I am hoping these springs fit my sedan
