What are High Beams (Helljus)?

High beams, or helljus in Swedish, are the most powerful forward-facing lights on your vehicle. Their primary purpose is to provide extensive illumination of the road ahead, far beyond what low beams offer, allowing you to react to potential hazards at higher speeds during periods of darkness or significantly reduced visibility. This enhanced visibility is vital for road safety, especially on unlit rural roads where dangers might otherwise go unnoticed until it's too late.

When Should You Use High Beams in Sweden?

In Sweden, the general rule is to use high beams as often as possible when driving in darkness or conditions of poor visibility, provided it can be done without dazzling other road users. This proactive approach ensures optimal visibility and safety. Specifically, you should consider using high beams:

• On unlit roads or motorways during nighttime.
• In heavy rain, snow, or dense fog if visibility is severely limited, though sometimes high beams can reflect and worsen visibility in fog.
• Whenever low beams do not provide sufficient illumination to safely match your driving speed.

Using high beams maximizes your reaction time to obstacles, pedestrians, cyclists, and animals on the road, which is particularly important in rural areas of Sweden.

When Must You Dip Your High Beams (Växla till Halvljus)?

While using high beams is encouraged for safety, it is equally critical to know when to switch to low beams (halvljus) to prevent dazzling others. Dazzling can temporarily blind other drivers, creating a severe road safety risk. According to Swedish traffic regulations, you must dip your high beams well in advance in the following situations:

• When meeting oncoming traffic: As soon as you see the lights of an approaching vehicle, you must switch to low beams. For trucks, be aware that their cabins are higher, so you might need to dip your lights as soon as you see their top marker lights over a hill.
• When following another vehicle closely: If you are driving at a short distance behind another vehicle, your high beams will reflect in their mirrors and dazzle the driver. Switch to low beams immediately.
• When the road is adequately lit: If you are driving on a stretch of road that is sufficiently illuminated by streetlights or other sources, high beams are not necessary and should be switched off.
• When meeting trains, trams, or ships: If there's a risk of dazzling the operators of these vehicles, you must dip your high beams.
• In very dense fog: Sometimes, high beams can reflect off the fog particles, making visibility worse rather than better. In such cases, low beams or fog lights are more appropriate.
