BS4 Compliant Motorcycles: Why They Come Without a Light Switch

The recent shift towards Bharat Stage 4 (BS4) emission norms and the implementation of Automatic Headlight On (AHO) features in motorcycles have changed the landscape of these vehicles. This article explores the reasons behind the absence of a traditional light switch and highlights the safety benefits of these new features.

Understanding BS4 and AHO

Bharat Stage 4 is an emission standard set by the Indian government to reduce harmful pollutants from vehicles. However, this discussion focuses on a related but distinct feature: the automatic headlight system. Why have motorcycle manufacturers eliminated the traditional light switch, and what does the AHO feature entail?

The Key Reasons Behind the Change

The absence of a light switch on BS4 compliant motorcycles is primarily due to the AHO feature, which is mandated as part of the safety standards. This feature ensures that the headlights are always on during specific times, enhancing visibility and reducing the risk of accidents.

Visibility Enhancement:

Headlights play a crucial role in improving visibility during low-light conditions. By keeping the headlights on, AHO ensures that riders are more visible to one another, which is especially important when riding in fog or during dawn or dusk. This feature is not just beneficial for motorcyclists; it also helps cars and other road users to spot motorcycles more easily, reducing the likelihood of accidents.

Safety Feature:

The AHO feature is a safety initiative by the Indian government to make motorcycles more visible on the road. This reduces the risk of blind spots and lowers the probability of accidents during low-light conditions. Studies have shown that accidents involving motorcycles are more prone to occur during low visibility, making the AHO feature a critical safety measure.

The Basics of AHO

AHO is a standard feature on all BS4 compliant motorcycles. This system automatically turns the headlights on and off based on the time of day. For instance, from dusk to dawn, the lights remain on permanently to ensure maximum visibility. However, riders may find this feature inconvenient during daylight hours, which is why there is a lot of discussion about modifying the system to allow for manual control.

Customization Options:

While AHO is a mandatory feature, some manufacturers offer optional switches to allow riders to turn off the lights during daylight. However, it's important to note that altering this system may void the warranty and affect insurance policies. It's recommended to consult with a mechanic or professional to ensure that any modifications are done safely and legally.

Government Initiatives and Guidelines

The Road Transport Ministry has mandated the AHO feature for all vehicles manufactured after April 1. These guidelines aim to enhance safety and reduce the risk of accidents on Indian roads. The government's initiatives in this area are part of broader efforts to make motorcycle riding safer for everyone.

Advantages of AHO:

Enhanced visibility and safety during low-light conditions Reduced risk of accidents involving motorcycles Improved detection by other road users

In conclusion, the absence of a traditional light switch on BS4 compliant motorcycles is a result of the AHO feature, which is a safety measure intended to improve visibility and reduce the risk of accidents. While the feature may be a challenge during daylight, riders have the option to customize it to suit their needs, as long as they are aware of the potential consequences.

Key Takeaways:

AHO feature is mandatory on all BS4 compliant motorcycles. This feature enhances visibility during low-light conditions. Customization options are available but may void warranty and insurance.
