Jim’s Tech Talk
By Jim Langley
In July we reviewed a Knog Blinder 900 headlight, which we liked a lot. It’s still regularly used and working just as nicely as it did during the review.
Several of you readers commented that you have Knog Blinder lights that work well for you too. Here’s our review with your comments at the bottom.
The other day Knog reached out sharing information on a recall of early batches of the Knog Blinder lights. They were manufactured with batteries that can fail and pose a fire hazard.
We’re sharing this so that any of you using the lights can check if yours is affected. If so you should stop using it and follow their procedure to get a free replacement.
Knog Lights Recall Safety Notice
Updated 6 days ago
We [Knog] have identified that several early batches of our Blinder front bike lights were manufactured with batteries that can fail and pose a fire hazard, risking injury and property damage.
The four products shown below – only those with the batch codes listed – are being recalled. All other Knog products are safe to use.
Knog will be providing a free replacement for every recalled bike light.

WHAT YOU NEED TO DO:
1. Complete the form
Please take the following actions as soon as possible to avoid any potential safety risks.
- Click the link below to complete the form. By completing the form, we’ll confirm if your light or lights are being recalled. Here is a link to the form: https://knogrecall.zendesk.com/hc/en-au/articles/13482112255247-Recall-Safety-Notice.
- If your light or lights are being recalled, we’ll ask you to register for a replacement. Be prepared to upload proof of purchase (if available), a photo of your bike light or lights, and current shipping information.
2. Dispose of the bike light or lights
After submitting your claim, please dispose of the bike light in accordance with your local regulations for lithium-ion batteries. Improper disposal can lead to environmental hazards or safety risks.
Do not put it in the trash. Do not send anywhere via post or courier. Do not place it in standard battery recycling boxes at stores. Because recalled lithium-ion batteries require special handling, they should be disposed of in accordance with your local and state ordinances, following the procedures established by your municipal recycling centre for damaged, defective, or recalled lithium-ion batteries.
HOW TO FIND THE BATCH CODE

After two failures of early Knog square taillights I gave up on the products. We have US companies with higher reliability.
I got a knog blinder 1300 at the end of last year and am very satisfied.
I liked it so much I got a second one for trips away from recharging opportunities, but turned out it was unnecessary, the charge lasts a long time.
I use all of the day flasher modes and the two lower-power headlight power modes for after dark..
I have a Lights In Motion lamps. First purchased their headlamp at Epicenter Bikes for over $100. Later purchased a simple lamp similar to the Knog Blinder. Lights in Motion was located at the old Fort Ord airport in Marina, CA. I was there yesterday to ask for product assistance. To my surprise, they’re totally gone. The business now located there said that Lights In Motion has gone out of business. Anyone know if that’s true?
Light & Motion, the US-based manufacturer of lights for biking, diving, photo, and video, has closed its operations. The company announced the closure in early 2025, citing challenges with domestic manufacturing, political winds against US manufacturing, and a decline in the sector as key factors in the decision to shut down after 35 years in business.
unfortunate as they had good products and GREAT customer service
