Can each Lumos Firefly Mini have different light colors or functions?
Yes, it’s an all-in-one light! One Lumos Firefly Mini can be used as a front or rear light and with or without turn signals (red,white and amber LEDs all in one). You can change the function of the light as often as you like within the RideLumos App.
Does it come with the Automatic Brake lights?
The Lumos Firefly Mini comes with an optional brake light feature. If you wish to have the automatic brake light feature, then you need the Lumos Remote that has a built-in accelerometer required to activate the brake lights on your Lumos Firefly Mini bike light.

Our product equipped with IPX6 waterproof rating, can be effortlessly mounted on bicycles, trailers, backpacks, and more. It is designed to withstand adverse weather conditions and have been tested up to have an operational tempreature range of 32℉ (0℃) to 120℉ (49℃).
Is Lumos Firefly Mini compatible with my Lumos helmet?
Firefly Mini can be mounted on Lumos Ultra Fly and Lumos Ultra Fly Pro helmet via a Port Adapter. The smart lights are also compatible with this range of products: Ultra E-Bike and Ultra, and the Lumos Remote. You will also be able to sync your settings across all of your devices via the RideLumos App. Note: Lumos Firefly Mini is not compatible with the Remote Lite (round; batter operated).
How long does the battery last? What is the charging time?
With a 240mAh rechargeable battery inside, Lumos Firefly Mini will last up to 14 hours, depending on the settings. Choose a hi-vis mode for maximum visibility on the road or battery-saver mode for the longest-lasting mode of up to 14 hours. It takes about 2.5 hours to fully charge your Lumos Firefly, and you can check the battery level on the go with the RideLumos App.

Just note that the silicone strap stretches up to 15cm (~6 inches).
Does it have any certifications?
Naturally! Both the Firefly and Firefly Mini complies with the electronics regulation standards and is certified accordingly. The Mini is certified to the relevant requirements as set out by the FCC in the US, CE in EU, and IC in the CA.
How can I activate the turn signals?
You have the option of using either the Ride Lumos App or a Lumos Remote (if you purchase one). For more info on setting this up, check out this article: https://support.lumoshelmet.co/hc/en-us/articles/13070449589399-Setting-up-Turn-Signals-Lumos-Remote-with-your-Firefly
I don’t have a Lumos helmet. Can I use the Lumos Firefly Mini?
Definitely! You can use one or more Lumos Firefly Mini lights with or without a Lumos helmet.
Are the (flashing) lights allowed in my country?
Firefly Mini has different light settings so you can always set them on the solid mode when needed. While in most areas flashing lights are allowed, traffic and (bicycle) lighting regulations differ in each country. We recommend checking the regulations of your area with the local authorities.
Do the lights meet the requirements of the StVZO in Germany?
At this moment it does not meet the StVZO requirements as flashing lights are forbidden in Germany when mounted on a bike. That said, flashing lights are allowed in traffic for example on helmets, backpacks etc. as long as they are not attached to your bike directly.If you’re cycling anywhere other than German roads, you do not require a light that's StVZO certified.
