The lights and battery packs are designed to minimize areas of ingress, but have not officially tested to be waterproof.

I have ridden through a rainstorm that left me soaked head to toe without issue. Just don't submerge the lights or the battery in water.

Yes, you may modify/repair your kit as you see fit. Any modifications will void the warranty.

Please refer to the Troubleshooting section of the Instructions page for the Bill of Materials for where to source replacement parts.

The wheel light kits have a one year warranty against manufacturing defects.

Yes, I offer free shipping in the US on orders over $75.

For orders outside the US, I split the bill. You only pay the shipping cost; I cover duties, tariffs, taxes, etc.

At this time, I only ship to the US and Canada.

I am exploring a way to sell internationally, but it would mean shipping the kit "batteries not included". The buyer would need to acquire 21700 lithium-ion cells from a local distributor.

Despite what the checkout page says, your package will be shipped Delivered Duty Paid (DDP) if you order from outside of the United States.

Unfortunately, the checkout page is the one page you cannot customize on a Fourthwall store.

The kits are made to order and usually ship within 3-7 business days, depending on how many orders are in the queue.

Because the kits contain lithium ion batteries, I have to ship using USPS Ground Advantage, which can take a few days.
