Bicycle helmet with turn indicators: is Signal right for you?
Published
Is a bicycle helmet with turn indicators right for you? The Pro Sport Lights Signal is particularly useful if you want to signal your turns using a handlebar button on your daily rides. The helmet has front and rear LED lights, wireless rear turn indicators and an included handlebar remote. Press L or R; the indicator switches off automatically after 10 seconds. If you are looking for a helmet with a visor, included ear warmers or a specific model for a speed pedelec, compare the other helmets first.
A bicycle helmet with turn indicators sounds straightforward, but there are a few practical questions to consider before choosing: how do the controls work, what needs charging, which size fits, and when would another helmet make more sense? This buying guide answers those questions using the current product specifications of the Signal bicycle helmet with lights and wireless turn indicators. This is product advice from Pro Sport Lights, rather than an independent road test.
How does the Signal bicycle helmet with turn indicators work?
On Signal, you operate the turn indicators using the included handlebar button. You do not need to reach for the helmet to select left or right.
- L: activates the left turn indicator.
- R: activates the right turn indicator.
- Automatic switch-off: the selected indicator switches off automatically after 10 seconds.
- M: switches off the turn indicator and controls the light modes.
According to the current product information, the remote, mounting bracket and rubber fastening strap are included. Before your first ride, check that the remote is securely fitted to your handlebar and that L and R activate the expected signal on the helmet.
Who should consider a Signal bicycle helmet?
| Your priority | Does Signal suit it? | Why? |
|---|---|---|
| Signalling turns from the handlebar | Yes | The wireless remote with L and R buttons is included. |
| Front and rear helmet lights | Yes | Signal has integrated LED lights at the front and rear. |
| A lightweight helmet | Possibly | The stated weight is 320 grams. Fit remains more important than weight alone. |
| A clear and a dark visor | No, not as a standard feature | The Signal product information does not list any included visors. Consider ClearView or ICE for this feature. |
| Ear warmers included as standard | No | This feature belongs to the linked ICE version and is not included with Signal. |
| Choosing a helmet for a speed pedelec | Check first | Choose according to the requirements for your vehicle and country; the Signal product page does not present it as a speed pedelec helmet. |
Signal therefore does not automatically replace every other helmet model. Its main benefit is the combination of a 320-gram helmet, integrated lights and wirelessly controlled turn indicators.

How to pair and use the handlebar remote
- Fit the remote: position the included handlebar button so you can operate L, R and M without unnecessary hand movement.
- Pair the components: press and hold the button on the helmet and the M button on the remote at the same time.
- Switch on the helmet lights: then hold the button on the helmet for 3 seconds.
- Test left and right: while stationary, press L and R and check that the correct signal appears at the rear.
- Check the automatic switch-off: according to the product specifications, the flashing signal should stop after 10 seconds.
Test the system again after repositioning the handlebar remote, charging the helmet or leaving the remote unused for a longer period. A function check before setting off helps you discover a disconnected remote before you are on the road.
Do the turn indicators replace hand signals?
Treat the turn indicators as additional communication with traffic behind you. They do not automatically make a manoeuvre safe or change local traffic rules. Keep looking around, anticipate other road users and follow the rules that apply where you ride.
Which size Signal bicycle helmet should you choose?
Measure your head circumference horizontally around the widest part of your head, just above your eyebrows and ears. Then compare it with the current Signal sizes:
- Medium: head circumference 50–56 cm.
- Large: head circumference 54–61 cm.
At 54–56 cm, both sizes fall within the stated range. Do not automatically choose Large for extra room. The helmet should fit securely and comfortably, without painful pressure points or loose movement. Signal is available in pearl and black.

Lights, light modes and charging
Signal has front and rear LED lights and charges via USB-C. The product information lists four light modes: steady light, slow flashing, SOS and daytime lighting. You control the modes using the M button on the handlebar remote.
The current product information does not give a fixed battery runtime that we can reliably use in this guide. Do not plan a ride around an assumed number of hours. Before setting off, check that the helmet is sufficiently charged and that the lights and handlebar remote respond.
- Charge the helmet at a regular time, for example after a few commutes.
- Check the front and rear LED lights before setting off.
- Test L and R while stationary.
- Also use suitable lights on your bicycle; helmet lights are an additional feature.
Choose Signal in three steps
- Measure first: is your head circumference within Medium 50–56 cm or Large 54–61 cm?
- Choose by function: do you mainly want wireless turn indicators operated from the handlebar, or would a visor or ear warmers be more useful?
- Check your intended use: does Signal suit your bicycle and the rules for your vehicle and country?
If the turn indicators are your main reason for buying and the fit is right, Signal is the first Pro Sport Lights model to consider. If a visor, included ear warmers or specific speed pedelec requirements matter more, start with the general helmet comparison.
