How Can I Make My Headlights Brighter

Update On

A bright and visible headlight is essential for your car. Your vehicle needs this brightness to allow you to see your environment adequately and allow other road users to see you on time. 

Stock halogen headlights sometimes don’t offer the necessary brightness. At times they have degenerated with age and have gotten dim. That means you probably need to replace them with new halogen lamps or upgrade to other headlights for vehicles.

But can you find these upgrades? And what kind of headlights work best for vehicles? And if you have been asking yourself how I can make my headlights brighter, you will find those answers right here.

Upgrade Your Headlights to a Higher Lumens

Your headlights determine how well you can see ahead. Vehicles generally have stock headlights with a brightness of between 400 and 500 lumens. This brightness illuminates a distance of about 10 meters (32.8 feet) which can suffice for many riders. 

Extra bright headlights

If you prefer to have a higher area illuminated, you can always upgrade your bulbs to higher lumens. Lumens are the standard measure for the brightness of LED bulbs. If, on the off chance, your vehicle is using halogen or HID bulbs, then you upgrade their wattage by several watts.

Be careful that you only upgrade your lighting to a considerable wattage or lumens. Upgrading by too high a gap from your stock lighting may result in fried circuitry. You can try the next step to avoid this possible scenario.

Replace Stock Headlights Using Similar Lights With Higher Output

Headlights have seen much advancement in their design in years gone by. This improvement makes it possible for you to purchase lights with the same wattage yet a brighter output than the pre-installed lamps.

Xenon lamps offer a lot of illumination of up to three times more than the stock halogen lights installed in older motorbikes. Vehicles tend to have more modern lighting installed, like xenon lighting. The only challenge to this kind of lighting is they consume more power than LED lighting.

Most manufacturers have therefore started making vehicle headlights using LED lights as they consume the least power among all the bulbs. This manufacturing direction has allowed the bikes to spend less power on lighting to allow the bikes to conserve power. But if you still want to install a higher-demand bulb, you can upgrade your battery pack.

Upgrade Your Battery Pack

Suppose you want to upgrade your battery pack to accommodate a bulb that consumes more power, then getting a battery pack with a higher voltage than the one installed can help you achieve this. Most vehicles with 36-volt battery packs have capacitors with 63 volts rating and 60 volts rated MOSFETs chips. 

These components allow them to handle battery upgrades up to 52 volts. While manufacturers always advise users to replace existing battery packs with similar packs from the same manufacturers, users can always get their circuitry assessed by an electrician to ascertain they can upgrade their battery packs with no adverse effect. 

Something to note is you need to get a battery pack that matches the amperes your motor control draws out. For example, a motor control made to draw 40 amperes out of a battery pack must have batteries with a minimum output of 40 amperes. 

A Simple Clean Does Wonders

Sometimes we forget to take care of our vehicles the way we should. In such times grime and dirt may have caked some parts of the bike, including the headlights. Consider assessing the light to see if it has any dirt that has covered its lens. Wash it off with a soft rug dipped in water with a grease-removing liquid soap, then rinse it off with clean water.

Remember not to soak the light in water as it may fog it up or, worse, leak into the light. While most modern vehicle headlights are made waterproof, protecting them from water immersion is vital as it can compromise them. 

Add Auxiliary Lighting

You can also increase the brightness of your headlights by adding auxiliary lighting to the existing ones. Most vehicles come with space on the handlebars you can utilize to add on extra high-powered lights you can use to increase the brightness of your current lights.

Since vehicle lights come with their housing, all you need is mounting space to enable you to install the extra lights. It would be best if you also had a little know-how to integrate these lights with the current ones. You can ask a qualified wiring mechanic to wire the lights up for you to avoid any complications. This point leads us to its relating point.

Properly Position Lights

Headlights sometimes don’t function as they should as they have been poorly positioned. You can lose the brightness of a beam if you face it in the wrong direction. You can position your beam using a blank wall at night while standing about 5 meters away from the wall. 

Loosen the lighting and play with it along the wall till you have it shining its light at the angle you desire it to hit the ground. Give it a few test runs until you are satisfied with its performance. Remember to keep it from glaring in the faces of other road users.

Factors To Consider When Buying Headlights for Your Vehicle

Compatibility With Your Vehicle:

Numerous manufacturers have produced aftermarket headlight products for vehicles. You must ensure the product you choose fits into the light outlet of the vehicle you have. You can check what the manufacturer has available and if it is modifiable to accommodate other diverse motor systems.

Power Input Requirements:

Another factor to consider is the power input requirements of the light you want. This requirement should align with the power output of the motor system you have on your vehicle. Most systems range between 36 volts and 52 volts with varying ampere outputs. Narrowing down the available power helps you match the power to the right headlight upgrade.

Power Consumption of the Bulb:

You also need to consider the power consumption of your bulb of choice. Different headlights come with different power consumption requirements. An example is HID or xenon lights that require some current to start up. LED lighting, on the other hand, spends very little electricity. Choose wisely based on these requirements. 

Light Modes:

Another thing to remember is if the lights come with different light modes and if they will serve you as you desire. Different light modes ensure you have an option between low and high beams, allowing you to save on electricity when you don’t demand a lot of brightness.

Keep in mind that you also need a headlight that is waterproof as you are using it for outdoor activities. Waterproofed lights always outlive their counterparts as they protect their circuitry better from water damage or short circuits.

Lastly, consider the budget that you have available. Vehicle headlights have a wide array available depending on the quality and the brand. This array ensures all people have headlights they can afford. Ensure you do not go for the overly cheap headlights as they might not last long.


Bright headlights are essential to your driving safety. You need them to make other road users aware of your presence. Do your due diligence before purchasing new headlights by ensuring your current ones have given you their best service.  Have you had an issue with headlight brightness in your vehicle?
