I love this new head gear from LUMOS its a ebike specific helmet with turn signal. MIPS rated.
Not only is the LED lighting top notch but the style is truly unique and futuristic. The coolest part is the face visor on a swivel where you can protect the top half of your face from the wind which always makes my eyes water at higher speeds. A small push button device is supplied for turning on the turn signals which attaches to the your handlebars.
The Lumos Ebike helmet is available on Amazon for $229. Get it here. Currently on sale for 20% off ($183).
It has 3 white LEDs on the front and two red ones on the rear. The clip is magnetized for easy snap on.
