5. What’s Next for AHO? The industry is developing smarter AHO technology, such as LED lights and region-specific adjustments. There’s also a push for more public awareness, so safety can improve without causing unnecessary inconvenience for riders.

What is (AHO) Automatic Headlamp On in Bikes and scooters?

AHO stands for Automatic Headlamp On. It’s a safety feature that makes riding a two-wheeler safer and easier to see. When you start your engine, the headlamp turns on by itself, so you don’t have to remember to switch it on. This simple system helps you stay visible and makes riding less stressful.

Here are some key highlights of the AHO feature:

1. Automatic Activation: You don’t need to look for a switch. With AHO, your headlamp turns on as soon as you start the engine, so you’re always visible on the road.
2. Enhanced Safety: Whether you’re riding in rain, fog, or on winding roads, AHO greatly improves your visibility. This leads to safer rides for you and others on the road. Being seen means being safe.
3. Regulatory Requirement: Since April 1, 2017, all new two-wheelers in India must have AHO. This rule aligns India with global safety standards and makes riding safer.

Why Was Automatic Headlamp On (AHO) Introduced in India?

India has one of the highest rates of road accidents, especially among two-wheeler riders. Poor visibility at dawn, dusk, and in fog is a major factor.

To address this, AHO (Automatic Headlamp On) was introduced. It makes two-wheelers easier to see for everyone on the road, from pedestrians to drivers of larger vehicles. This should help make roads safer for everyone.

What are the implementation and regulations of Automatic Headlamp On (AHO) in two-wheelers in India?

1. Legal Regulations

MoRTH notified AHO as compulsory for motorcycles and scooters post-April 2017, based on the Justice Radhakrishnan Committee’s recommendations, following Safer Roads Foundation advocacy. No manual on/off switch allowed; non-compliance blocks type approval under CMVR 1988, with fines up to ₹1000 for tampering under Section 190. Applies uniformly to BS4/BS6/EV models, verified during ARAI certification and RTO registration.

2. Technical Implementation Standards

Headlight circuit wires directly to ignition coil or ECU, powering low-beam (35-55W halogen/5-10W LED) within 2 seconds of engine start; alternator sustains output post-cranking. AIS standards (e.g., AIS-010 for headlamps) ensure 1000+ lumen brightness and no glare exceedance; manufacturers like Hero/Honda integrate via relays/ECUs without sensors.

3. Compliance and Enforcement

All post-2017 models from Hero, Honda, Bajaj, TVS, and Royal Enfield must feature AHO for factory clearance; pre-2017 bikes are exempt but encouraged via DRL kits. PUC/RTO inspections check functionality; disabling voids warranties/insurance and risks impoundment amid 30% tampering rates. 2025 updates tie to BS6 Phase 2, pushing LED mandates for efficiency.

How do bike and scooter manufacturers implement AHO in their models in India?

Since 2017, all new two-wheelers in India must have Automatic Headlamp On (AHO), which turns on the headlights automatically when the engine is running. Manufacturers use simple electrical setups suited to each model, focusing on safety, efficiency, and rider satisfaction as rules change.

1. Core AHO Implementation Mechanism

Manufacturers connect the low-beam headlight directly to the ignition coil or ECU, so it turns on within 1-2 seconds of engine start. The alternator keeps the light running, whether it’s a halogen or LED bulb. Riders still control the high beam and pass functions. This setup meets MoRTH standards and costs about ₹200-500 per unit to make.

2. Brand-Specific Wiring and Tech Strategies

Hero MotoCorp dominates the mass-market 100-125cc commuter segment with models like Splendor Plus and HF Deluxe, featuring basic relay-based AHO tied to magneto ignition, minimising startup drain via upgraded 120-140W alternators. Honda integrates ECU-controlled AHO on Shine 125 and Activa scooters, auto-defaulting to low beam and phasing out toggles entirely for seamless BS6 compliance.

Royal Enfield employs robust relay circuits across Classic 350 and Hunter 350, routing power post-ignition to handle 350cc loads. However, models add optional LED pilots for glare reduction. Bajaj (Pulsar NS200) and TVS (Apache RTR 200) leverage digital ECUs for precise activation, with premium scooters like Yamaha Aerox using sensor-assisted dimming previews.

Working of AHO Automatic Headlight On (AHO) System

1. The battery serves as the system’s primary power source.
2. When the ignition switch is engaged, it activates the AHO (Automatic Headlight On) controller, which automatically supplies power to the headlight.
3. The alternator generates a continuous power supply while the engine runs.
4. Consequently, the headlight illuminates as soon as the engine is started and remains on throughout the operation.
5. Riders can adjust the headlight’s intensity using a high/low beam switch.
6. However, no manual switch is available to turn off the headlight completely.

Working of Manual Switch Headlight System

1. The battery is essential for supplying power to the system.
2. The ignition switch is crucial in activating the electrical system.
3. A manual headlight switch gives the rider control over powering the headlight on and off.
4. A high/low beam switch allows the rider to switch between high and low beam settings to adapt to different driving conditions.
5. There is also a flash-to-pass switch activation of the high beam.
6. While the engine runs, the alternator generates continuous power to support the system’s electrical needs.
