CatEye Volt 400 Duplex Front and Rear Helmet Light

Season :

Brand : Cateye


Weight : 0.2KG

The Volt 400 Duplex Helmet Light puts out a powerful 400 lumens up front to illuminate the road/trail ahead. Also, as it's attached to your helmet, you can point the beam exactly where you want it, rather than it being limited to how much you can turn your bars!

Front and Rear Visibility

It also features a bright 50 lumens rear light at the back of the unit, to make you more visible to upcoming traffic. USB rechargeable, and packed with a range of settings, the Duplex light will help you to keep up that commute to work through the darker months!

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
