Auxiliary lights can only be used in specific conditions and situations. The general rule across Nordic countries is that they may be used only in low light or darkness when they do not dazzle other road users. Their use in urban areas is prohibited, and they must be switched off when approaching other vehicles. Legal use also requires proper installation and type approval.

What Does the Law Say About Using Auxiliary Lights?

Nordic traffic laws, including those in Finland and Sweden, define strict rules for using auxiliary lights. The principle across these countries is that auxiliary lights are allowed only when they improve road safety without disturbing other drivers.

Lights that can dazzle or confuse other road users are prohibited throughout the Nordic region. These regulations aim to protect all road users and prevent accidents caused by glare. Auxiliary lights must be properly installed and type-approved according to EU standards. Misuse can lead to fines and temporary vehicle bans in all Nordic countries.

Difference Between Auxiliary Lights, Work Lights, and Marker Lights

• Extraljus complement standard headlights and may be used while driving under certain conditions.

• Arbetsljus are intended only for use when the vehicle is stationary for work purposes.

• Marker lights indicate the outline of a vehicle and improve visibility.

Lazer auxiliary lights are a prime example of high-quality LED lights providing bright, even illumination. Work lights must never be used while driving in any Nordic country, whereas marker lights may be used as part of the vehicle’s standard lighting.

When Can Auxiliary Lights Be Used While Driving?

Throughout the Nordic countries, auxiliary lights may be used on rural roads, highways, or motorways in darkness or low visibility. They must be switched off immediately when meeting or overtaking other vehicles.

Permitted situations include:

• Dark conditions on rural roads

• Fog, rain, or snowfall

• Dusk when headlights alone are insufficient

• Off-road driving on private roads

Lights must always be switched off upon entering urban areas or when encountering traffic. Misuse endangers road safety and is illegal across all Nordic jurisdictions.

Why Are Auxiliary Lights Prohibited in Urban Areas or When Meeting Other Vehicles?

The main reason for prohibiting auxiliary lights in towns and during encounters across Nordic countries is glare. Bright lights can temporarily blind oncoming drivers, causing serious accidents.

Urban street lighting provides sufficient visibility, making auxiliary lights unnecessary and disturbing. In Sweden and Finland, misuse can result in fines ranging from €100-500, license suspension, or, in severe cases, criminal liability if an accident occurs.

How to Legally Install Auxiliary Lights

Legal installation requires EU type-approved lights and proper placement on the vehicle according to Nordic regulations. Lights must be installed symmetrically and at the correct height.

Considerations for installation:

• CE marking and EU type approval

• Correct installation height and angle

• Connection with vehicle headlights

• Separate shut-off switch

Lazer auxiliary lights come with ready-to-install kits and meet all EU requirements for use in Nordic countries. Professional installation is recommended to ensure proper alignment and compliance.

Summary – Safe and Legal Use of Auxiliary Lights

Responsible use of auxiliary lights enhances driving safety when Nordic regulations are known and followed.

Key points to remember:

• Use only in darkness or low light

• Switch off when meeting other vehicles

• Choose EU type-approved lights

• Install and adjust properly

High-quality lights, such as Lazer products, provide optimal performance and durability while meeting Nordic safety standards. When used correctly, they significantly improve visibility and road safety in the challenging dark conditions common throughout Scandinavia.
