Choosing a bike helmet with lights: a practical guide to cycling safely and being seen

A bike helmet with lights combines head protection with added visibility. It’s useful for commuting, cycling in town and leisure rides in the dark or in poor weather. However, a built-in LED light doesn’t automatically mean a helmet is right for every cyclist.

Most disappointing purchases come down to three simple mistakes:

  • Choosing the wrong size: a helmet that’s too loose can shift while you’re riding. One that’s too tight can quickly become uncomfortable.
  • Focusing too much on the light settings: several flashing modes might sound appealing, but battery life, visibility and ease of use matter more.
  • Confusing helmet lights with full bike lighting: a light on your helmet can make you more visible, but it doesn’t always replace a required bike light. So check the current Dutch traffic rules and bike lighting requirements.

What to look for in a bike helmet with LED lights

1. Measure your head circumference first

Use a flexible tape measure around your head, about two centimetres above your eyebrows. Keep the tape level and note the measurement in centimetres. Compare it with the manufacturer’s size guide.

For example, for the DKONI HS-086 models:

  • Size M: 55–58 cm
  • Size L: approximately 58–61 cm

A size label such as M or L isn’t universal. Always check the measurements in centimetres. An adjustment dial and adjustable chin strap help you fine-tune the fit, but they can’t fully compensate for choosing the wrong base size.

The helmet should fit securely without creating pressure points. The chin strap should sit close against your chin without digging in. Wear the helmet level; don’t position it too far back on your head.

2. Consider the construction, ventilation and weight

Many bike helmets combine a hard PC outer shell with EPS foam on the inside. According to the product information, the DKONI HS-086 has an in-mould construction, a PC shell and EPS foam.

Practical details also matter for everyday cycling:

  • Ventilation openings: 15 openings on the HS-086 and 20 on the HS-158.
  • Inner pads: removable pads are easier to clean.
  • Weight: a lighter helmet can be more comfortable on longer rides, but weight alone tells you nothing about the fit.
  • Adjustment mechanism: a dial at the back makes it easier to adjust the fit while you’re out.

A well-ventilated bike helmet is particularly comfortable on longer rides or in warm weather. Bear in mind, though, that large ventilation openings don’t automatically make a helmet suitable for every weather condition.

3. Check the lights and power supply

A bike helmet with LED lights may have a fixed rear light or a removable one. In either case, check:

  • Whether the light is USB rechargeable.
  • How many light settings it has.
  • The stated battery life.
  • Whether you can remove the light for charging.
  • Whether you also need a front light and a rear bike light.

According to the product description, the DKONI HS-086 has a removable USB-rechargeable rear light with two settings and a stated battery life of around 3 to 5 hours. So charge the light before setting off on a long evening ride.

The DKONI HS-158 has lights at the front and rear: five white LEDs at the front and thirteen red LEDs at the rear, with four rear-light settings. This makes it an interesting option for cyclists looking for an integrated lighting system. The product information lists this helmet as having CPSC, CE and ASTM certification. Always check the current product documentation and the applicable requirements for these markings before buying.

Common buying mistakes

Looking only at the colour and design

A bright colour can help you be seen, but fit and light placement are more important. A helmet might look good but still not fit your head properly.

Buying a light without planning when to charge it

A USB-rechargeable bike helmet is convenient, but its lights need charging regularly. For example, make charging part of your routine after your commute. For longer rides, a separate rear bike light can be a practical extra.

Using a mountain bike helmet for every kind of cycling

A mountain bike helmet often has a visor, extra coverage at the sides and more ventilation. These features are useful on unpaved paths, in wooded areas and in changeable weather. For everyday cycling in town, a simpler model may be less bulky.

Frequently asked questions about bike helmets with lights

Is a bike helmet with lights compulsory?

A helmet and bike lights are two different things. Bike lighting requirements depend on the bike and the conditions you’re riding in. A light on your helmet can make you more visible, but always check that your bike itself also has the required lights and reflectors.

How long do the lights on a USB-rechargeable bike helmet last?

It varies by model and light setting. The DKONI HS-086 is listed as lasting around 3 to 5 hours. Flashing and steady-light settings may have different battery lives. Charge the light regularly and test it before an evening ride.

When should I replace my bike helmet?

Replace your helmet after a hard fall or collision, even if there’s little visible damage on the outside. Also check the shell, EPS foam, chin strap and adjustment parts regularly. If in doubt, follow the manufacturer’s care and replacement instructions.
