1.​ Never ride in darkness again

​1.1.​ Fits In Your Pocket

You will never have to worry about having your bike lights stolen again. You can carry them for hours without even noticing. The first bike lights designed to be carried in your pocket along with your phone and wallet.

You are able to ride wherever you want and have the peace of mind that your lights are safe in your pocket. 

​1.2.​ Easily Removed

You will be less annoyed when you park your bike in public. You will be able to quickly pack up and down your bike. The lights slide off from the strap easily and quickly.The silicone handlebar mounts stay on the bike so you only carry the expensive part.

​1.3.​ Automatically Turns Off

Do you ever forget to leave your lights on and then come back to find out that they are flat? Never return to your bike again and find out your lights are flat.

After two minutes of no movement, bunc lights turn off. Once you move them again they automatically turn on.

We call this the “Intelligent Sleep/Wake” feature.

​2.​ You Will Be Seen

​2.1.​ Narrow Beam

A single high-power LED projects a single beam of light meaning you can be seen from a distance.

The same clip that mounts onto your bike can be clipped to your shirt for running, skateboarding or any other activity. 

​3.2.​ Waterproof IPX6

bunc lights can be used in any storm you can ride through. They have a waterproof rating of IPX6, meaning they can handle direct blasts from high-pressure jets.

I recommend this product
Extremely satisfied customer

I’m simply loving both my bunc headlight and taillight. I’m experiencing a greater sense of safety with maximum visibility out on the bike trails and dark roads this time of the year. I must say the Intelligent sleep / wake is pure genius. I can’t recommend both products enough


That gives us such a good feeling that you are feeling safer out on the road Michael! Awesome to hear. We think the intelligent sleep/wake is pretty neat too ;)
