Guía de luces delanteras para Cargo Bike: Brillo, color y seguridad explicados

At Regen, where we design and manufacture complete cargo bike systems for families and fleets, we often get asked about front lighting — especially as riders begin commuting at dusk, navigating low-light city alleys, or delivering across darker rural routes. Lighting is not just about visibility; it’s about road legality, rider safety, and even battery efficiency.

In this guide, we answer the most common questions about cargo bike front lights, from how many lumens you actually need to whether 4000 lumens is excessive — all backed by standards and real-world use cases.

What Is a Front Light on a Cargo Bike?

A cargo bike front light is a forward-facing illumination device mounted to the handlebar, fork crown, or cargo rack. It is designed for:

• Active lighting (to light up the rider’s path)
• Passive visibility (to alert others of your presence)

Unlike basic commuter bikes, cargo bikes may carry passengers or goods, often operating at higher loads and speeds. This makes reliable front lighting not just helpful — but essential for road legality and rider safety.

For cargo bikes, we recommend a wide-angle beam that lights both the road and the sides — especially with a long front box that can cast shadows. Integrated lights that draw power from the main e-bike battery offer reliability and convenience.

Do You Really Need a Front Light on a Bike?

Yes — both legally and practically, a front light is essential.

• Legal Requirement: In most EU countries and across the UK, a white front light is mandatory when riding at night or in low-visibility conditions (EN 15194 and local traffic codes apply).
• Practical Necessity: It allows other road users to see you and helps you see the road ahead, especially potholes, curbs, or debris — particularly important on a loaded cargo bike.

Real use case: Urban delivery riders often report that without a proper front light, visibility drops by over 50% after sunset — even on well-lit streets.

Is a Front Light Required on a Cargo Bike?

Yes, in most European countries and the UK, front lights are legally required for bikes used at night or in poor visibility.

According to EU regulation EN 15194 (for electrically assisted pedal cycles):

• A white or selective yellow front light must be fitted.
• The light must be visible from at least 100 metres.
• For road approval, the light beam must not dazzle other road users (cut-off beam).

In Germany, the StVZO (Straßenverkehrs-Zulassungs-Ordnung) standard mandates specific beam shaping, brightness, and power source stability, especially for e-bikes.

What Colour Light Should Be on the Front of a Bike?

El correct colour for a front light is either:

Selective yellow (less common, used in fog or low-contrast conditions)

White (most common and legal across all regions)

EU and UK regulations (EN 15194, StVZO in Germany, Road Vehicles Lighting Regulations in the UK) specify that the front light must emit a steady or flashing white beam.

Important: Blue or coloured lights at the front are often illegal and can be mistaken for emergency vehicles or cause visibility issues for other road users.

Consejo: Warm white lights (4000–5000K colour temperature) are more comfortable for night riding compared to harsh blue-tinged LEDs.

How Many Lumens Should a Front Bike Light Be?

Brightness is measured in lumens, which quantify the total amount of visible light emitted.

Para bicicletas de carga, we usually recommend 600–1200 lumens, depending on:

• Whether you ride at night
• Road lighting conditions
• Speed and cargo weight (which affect stopping time)

Pro Tip: Choose a light with adjustable brightness settings (e.g. low-mid-high) to balance power consumption and visibility.

Is 1000 / 3000 / 4000 Lumens Too Bright for a Bike Light?

It depends — but yes, it can be too bright in some conditions.

Why excessive brightness can be a problem:

• Dazzles oncoming riders or drivers
• May violate legal standards in places like Germany (StVZO-compliant lights cap beam intensity)
• Wastes energy — drains your e-bike battery or external light pack faster

Solution: Look for lights with anti-glare lenses or a cutoff beam — these direct the light downward, lighting the road without blinding others.

Extra Features to Look for in a Cargo Bike Front Light

• Integrated Mounting System: Especially important for front-loading cargo bikes. A fork-mounted or rack-integrated light reduces vibration and improves beam stability.
• Waterproof Rating: At least IPX4 for rainy commutes.
• Daytime Running Mode: Improves visibility in daylight — increasingly found in cargo delivery fleets.
• Battery Integration: For e-cargo bikes, a front light that draws from the bike’s main battery is ideal — fewer components to charge or manage.
• Standlight Function: Some high-end dynamo or integrated lights remain lit for a few minutes after stopping — useful for red lights or short stops.

Legal & Safety Standards to Consider

When purchasing or integrating a front light system, check for compliance with:

• EN 15194 – European e-bike safety regulation, includes lighting requirements
• StVZO – German road-use lighting standard (if exporting or selling in Germany)
• UN ECE R113 – For beam patterns and light spread, especially relevant to larger electric vehicles
• RoHS / CE – Electrical component safety and environmental compliance

What Makes a Good Cargo Bike Front Light?

A good cargo bike front light is crucial for safety, especially given the typically larger size and heavier loads of cargo bikes. Here’s a breakdown of what makes a light effective:

1. Brightness (Lumen/Lux Output):

• High Lumens: Cargo bikes need significant light output to illuminate the path ahead, particularly when carrying heavy loads that might obscure the road or when riding in areas with limited street lighting. While a minimum of 100-200 lumens is often cited for regular bikes, cargo bikes benefit greatly from higher outputs, often in the 500-1000+ lumen range, especially for unlit roads or trails. Some e-bike specific lights can even go up to 1800 lumens or more.
• Lux vs. Lumens: While lumens measure total light output, lux measures the intensity of light at a specific distance and area. Lights designed with a good beam pattern (see below) can have lower lumens but still provide excellent illumination where it’s needed most due to optimized lux.

2. Beam Pattern:

• Wide and Even Spread: Unlike road bikes that might benefit from a more focused beam for speed, cargo bikes need a wide and even beam to illuminate the broader area in front of the bike, including the cargo area and potential obstacles to the sides.
• Cutoff Beam (StVZO Compliant): Lights with a horizontal cutoff beam are highly recommended, especially if you’re riding in traffic. This design directs light onto the road and prevents blinding oncoming cyclists and drivers. This is a common feature in European (StVZO) compliant lights.
• No Hot Spots: A good beam should be smooth and consistent, without overly bright “hot spots” that can create shadows and reduce overall visibility.

3. Power Source and Runtime:

• Battery Powered (Rechargeable): Many modern cargo bike lights are USB-rechargeable. Look for long runtimes, especially if you do extended rides or forget to charge frequently. USB-C is a convenient charging standard.
• Dynamo Hub Powered: For ultimate convenience and “always-on” lighting, a dynamo hub integrated into your front wheel is an excellent option. It generates power as you ride, eliminating the need for battery charging. This is particularly popular on European cargo bikes.
• E-Bike Integrated: If you have an e-cargo bike, look for lights designed to integrate directly with your e-bike’s battery system. These lights often offer higher output and consistent power without needing separate batteries. Ensure the light’s voltage matches your e-bike’s system (e.g., 12V, 24V, 36V, 48V).

4. Mounting Options:

• Secure and Stable: Cargo bikes often experience more vibration and heavier impacts. The light needs to be securely mounted to withstand these forces and maintain its aim.
• Appropriate Placement: Consider where the light will be mounted on your specific cargo bike. Some cargo bikes have dedicated mounting points, while others may require creative solutions. A higher mounting point can often improve visibility for the rider and to other road users.
• Clearance: Ensure the light doesn’t interfere with your cargo, steering, or other accessories.

5. Durability and Weather Resistance:

• Robust Construction: A cargo bike light should be built to last, with a durable casing (often aluminum) to withstand daily use and potential bumps.
• Waterproof/Weather-Resistant: Look for an IPX4 rating or higher to ensure the light can withstand rain and splashes.

6. Additional Features:

• Multiple Modes: While a strong constant beam is essential for seeing, flashing modes can increase your visibility to others during daylight hours or in busy urban environments. Some lights also offer an “adaptive” mode that adjusts brightness based on ambient light.
• Daytime Running Light (DRL): Studies show that using lights during the day can significantly reduce the risk of collisions. A dedicated DRL mode, often a less intense but highly visible flash, is a valuable feature.
• Side Visibility: Lights with side cutouts or additional side-facing LEDs can improve your visibility from angles other than directly in front, which is important for intersection safety.
• Power Bank Functionality: Some battery-powered lights also double as power banks, allowing you to charge your phone or other devices on the go.
• Easy User Interface: Simple, glove-friendly buttons and clear mode selection are a plus.

Where Should the Front Light Be Mounted?

Correct positioning ensures safety and avoids shadowing. Here are common options:

For front-loading cargo bikes, handlebar lights can be insufficient. We often recommend dual lighting systems:

• Primary light on cargo rack or frame
• Secondary light on handlebar
