If I order a light, when will I receive it?

Orders placed by 2:00 PM PST ship same day. Domestic (US) orders usually make it in 3 to 5 Business days. International orders ship via Express service and arrive within 3-5 business days. 

Where is Blink Steady shipping from?

Our fulfillment partner Mission Bicycle Company ships out of San Francisco, California.

What comes with Blink Steady?

You’ll get the light itself, 2 name brand AAA batteries and a 2mm allen wrench and Torx wrench for installation. All lights now come with both Torx and Allen screws and wrenches.

Will the light turn off at traffic lights?

Nope. Our light stays on when it senses ANY motion at all, even the little sways and fidgety movements when at a stoplight, and stays on for 1 minutes after it's stopped completely. Not to worry.

My seatpost is blocked by my basket, can I install Blink / Steady somewhere else on my bike?

Blink / Steady is small and sleek because it does not incorporate a universal clamp. 

Will it leave a mark on my seatpost?

No. The setscrew that attaches the Blink / Steady to your seat-tube has a soft nylon tip. You can tighten it all you want and it won't leave a mark.
