Autofy NightHawk 40W Bike LED Headlight Review 2026: Brighter H4 Upgrade for Rs 1,199

Diwali shopping, late office rides, early winter fog on the highway: October to January is when most of us suddenly notice how weak our bike headlight really is. If your bike or scooter still runs a yellowish halogen H4 bulb, the Autofy NightHawk 40W is a plug and play LED upgrade at Rs 1,199. Here is an honest look at whether it is worth it.

What does H4 mean on a bike headlight?

H4 is a standard bulb type with a P43t base. One H4 bulb carries two filaments, one for low beam (dip) and one for high beam, which is why a single bulb handles both beams on most single headlamp bikes. Car H4 bulbs are typically rated 60/55W, while many two-wheeler H4 bulbs are 35/35W at 12V.

Which Indian bikes and scooters use H4 bulbs?

A large number of commuter motorcycles and scooters sold in India over the years have used an H4 type halogen headlight bulb, but this is not universal. Many newer models now come with factory LED headlamps, and some older bikes use HS1 or other bases that look similar. The safest check takes two minutes: open the headlamp, pull the stock bulb and read the marking on its base (it should say H4 or P43t), or check your owner's manual.

Autofy's own product page is clear: NightHawk is for bikes and motorcycles with an H4 headlight connector only, runs on 12V DC, and is not for cars. If you drive a car with H4 sockets, look at the Autofy Falcon H4/H19 car LED headlight instead.

Halogen vs LED: is a 40W H4 LED worth it for your bike?

The short version: a good LED gives whiter, brighter light for similar or lower power draw, and lasts far longer than a halogen filament. Here is how NightHawk compares with typical H4 halogen bulbs.

Notice the low beam: NightHawk is rated at 20W on dip, which is the beam you should be using most of the time in city traffic and fog. That lighter load on your bike's electrical system is a real plus over a 35/35W halogen.

Is a bright white LED legal and safe on Indian roads?

Brightness is only useful if it lands on the road, not in the eyes of the oncoming rider. The Ministry of Road Transport and Highways has published draft amendments to the Central Motor Vehicles Rules that propose lower maximum headlamp intensity for two-wheelers (100,000 candela, down from 150,000), low beam only automatic headlamps on new two-wheelers and a 6,500K cap on headlamp colour temperature. These are draft proposals, not final rules, and reports differ on the start date (April 2027 or April 2028).

NightHawk is rated at 6500K, right at that proposed limit. Whatever the final rules say, ride responsibly:

• Aim the beam low after fitting. Park facing a wall at night and check the cut-off sits below the height of the bulb.
• Use low beam in the city and when another vehicle approaches; flash high beam only on empty roads.
• In fog, stay on low beam. High beam bounces off fog and reduces your own visibility.
• Keep the headlamp glass clean. A quick wipe with a 1200 GSM microfiber towel makes a visible difference.

How to install the NightHawk H4 LED on your bike

• Switch off the ignition and let the old bulb cool down.
• Open the headlamp (remove the visor or headlamp screws as per your model) and pull off the rubber dust cover.
• Unplug the stock H4 bulb, release the retaining clip and confirm the base says H4 / P43t.
• Seat NightHawk in the same slot, lock the clip and plug in the connector.
• Test low and high beam before closing anything. If the light does not switch, check plug orientation.
• Check clearance for the cooling fan, refit the dust cover if it fits without pressing on the fan, then close the headlamp.
• Re-aim the beam against a wall as described above.
