The increase in vehicular traffic on Indian roads has led to a significant rise in the frequency of horn usage, particularly in city driving conditions and during peak traffic hours. Existing electro-mechanical horns are designed to have a mission life of 100,000 cycles according to Indian standards IS 1884 [1]. However, the intensified usage patterns have prompted a re-evaluation of the efficacy of these requirements. Studies reveal that the average horn blow frequency for normal usage vehicles is approximately three times per kilometer. When extrapolated to various usage categories, such as public transport and privately owned vehicles, observed increase in average horn blowing frequency per kilometer. When extrapolated, this corresponds to more than 4 lakhs cycles for a vehicle mission life of 2.5 lakhs kilometers. This insight drives the need to review and update validation test specifications to better align with customer usage patterns, thereby enhancing component reliability. By doing so, we can also predict potential failures or issues at an early development stage of components or project, leading to a more robust validation process and ultimately improving overall customer satisfaction. Additionally, for electro-mechanical horns field failure issues of horns not working, early kilometers tuning, and bobbin melting are increasing due to this rise in the frequency of horn usage. This emphases for review and optimization of horn validation test specifications.
