Introduction: Make Your Scooter/ Motorcycle Headlight Brighter by 80%

About: Necessity is the Mother of Inventions they say, I live in challenging land called INDIA. where the Sub par conditions like power issues, heat, Dust and environmental factors are just tough! and They have for...

I have this Lil' Scooter named Honda Activa.

And like most other 2 wheelers, It has so called "Headlights" that are dim as candles.

Stay with me and you'll learn how its easy to make them very bright and for not much.

Step 1: The Culprit

Most of the people might be thinking that the weak link for poor illumination is the weak electric system, however that being true, the worst thing is bulb itself.

The standard 2 wheeler bulb spec is dual filament 35/35 tungsten Globe. That generates a dismal 600 lumens, dimmer than most modern flashlights.

Step 2: What to Do and How to Do It...

I just casually opened the headlight and found that the poor 35W bulb looked more like car H4 55w lamps. And i thought "Why not!" If i can retrofit a proper Halogen 55W car headlight bulb, I can have a good 1100 Lumen output, about 80% increase!

However the Bulb was not a straight fit but Fret not! Use a plier to slightly bend the lower tabs as shown in the Pics, and it fits perfectly! Proper alignment too.

Step 3: Fire It Up!

As the H4 and Scooter bulb bases are little different, Simply buy a H4 holder and wire it into the factory power supply. Both Bulbs are 3 wire configuration so you should'nt have any problem here. Do check for proper High-Low Beam operation before finalizing anything.

Use a multimeter to help out with wirings.

Step 4: Enjoy.

I've been using the activa for 2 months now with the mods and zero problems yet.


1>.the beam pattern with 55w upgrade is same which means less glare compared to other mods.
2>.If you are worried about electrical load-
activa alternator is designed for maximum load of 35w headlight
21w turn signal
21w brake /rear light,
5w number plate light /meter light
10w horn.

hence it's capacity is easily sufficient unless you're trying to use everything at once.

This should not happen. Please get the scoot checked by decent mechanic to see if there is some short in the wiring or other issue.

this type of light would consume a huge amount of electric power so instead of using this use an LED lamp that is much more effective and doesn't affects the power in the scooter

Dear sir,

The Intent of this 'able is to increase illumination while keeping the Scooter stock and legal as much as possible. LED lamps are not approved by Transport Office. Also, the LED beam pattern is not optimized for road use and would generate huge glare to oncomers.

Meanwhile, do take a look at full LED OFF ROAD lights 'able which i've made for SUVs and like.

This is natural to happen. As the dynamo is tied to RPM.

Only option is to convert Scooter electricals to DC and hence power the headlight by Battery.

I connected my headlight to battery in my Bajaj CT 100. Will it have any adverse effect?

Also, can I upgrade my stock headlight( Halonix 35/35W) with any LED or HID, without violating the traffic rules?

Thanks in advance!

user

It appears you have converted to DC by connecting to battery. There should be no adverse effect. Battery may run down if you use a lot though. With DC convert you can go for LED bulb. HID not recommended for any 2 wheelers. try going for a warm white LED bulb. Traffic rules are a grey area in this regard.

user

yes. these should be good.

I'm having a 2017 Yamaha Ray Z BS4 with auto headlamp on and I feel the headlights are very poor. The bulb is HS1 35W Halogen and battery is 5 A.

What's the best stock headlamp upgrade ?

Thanks in advance.

These days the best option would be to go with good quality LED bulb with Glare shields. However this will only work if Voltage to the bulb is DC. Does the brightness go up and down with throttle? Then its not DC. In that case go with the guide mentioned above here.

@bhvm: Thanks for the reply. But my Ray is under warranty. So I'm planning to stick with 35W bulbs if possible. The scooter is AC.

What would you recommend in this case?

Thanks in advance.

user

In that case the best option is to go for premium Philips/Osram Bulbs. Upgrade will be very mild but it will preserve warranty.

Hello there,
Nowdays I am riding tvs jupiter and want to ask u that the method u have shown can be applied on my jupiter or i have to use a relay for it. Can u provid some links from where i can buy these 55w white halogen bulbs..

1. method remains same. Just wiring and routing will be slightly different as per bike model. Suggest you approach mechanic if you do not understand wiring.
2. These aren't white bulbs. Normal Car bulbs. I do not suggest white bulbs as glare is more.

Hello Sir,

Recently I brought a Honda Shine SP bike & I'm facing headlight brightness issue. Turned on headlight at idle RPM is almost like headlight is turned off, it is very dim @ 3k to 4k RPM, if throttle is full it give 90% to 95% brightness of it actual brightness.(Pass light give the actual brightness).

I earlier had Hero Honda CD Dawn, I didn't had this problem to it even though it was 13 years old technology.

I talked to higher authority service man in Authorized Honda Service Center, I got unsatisfactory reply, they all are doing donkey work.

Can you please tell me what should I do..??

If all bikes are behaving the same, Manuf has installed a very poor quality dynamo and there is no easy way around it. You may choose to re-winding the stator which will increase power but also void warranty.

Yes weak dynamo will offer very slow battery charging.
