Faulty - drains the battery

I have had to change the front light batteries twice, despite only using for a maximum of one hour. Wouldn’t recommend.

Missing cover

I think the lights are probably ok. However one set had a cover missing. Emailed and still haven't heard back, which is about 3 weeks ago

Great Light combo for the price

The head light throw is decent for average speed night rides. The unit seems to be heating up quite a bit after 15 to 30 mins of use. The tail light is great. Visisbility is quite good. But it would've benefitted ore with strobe or blinking mode.

Good combines light set

For occasional tourer this makes for s decent light set. The back light have good ambience but lacks modes, such as blinks etc. So reducing a star for that. Front light is decently lit for a totally black road or nominally lit road use, have to yet check it on trip but a rainproof light is great to have. Good thing is these set of lights comes with alkaline batteries so great to use after purchase, and alkaline batteries should be used for longer duration of light use. This is second set so have used this for couple of weeks before.

Poor battery life

Changed 2 set of 3 AAA battery in 1.5 Week. Max can last for 1.5hours.

Hi Arun,

I'm sorry to hear about your dissatisfactory experience with the ST 110 bike light set. The front light can normally last 33 hours in constant mode and 44 in eco mode while the rear light should last 102 hours, though this may change depending on battery brand or variant. However 1.5 hours does sound extremely low vs the specified runtime. Our User Happiness Team in our Singapore Lab Store will be pleased to assist and resolve your issue as soon as possible. Please chat with us directly on this page: CONTACT US.

Thanks to feedback provided by cyclists and other road users (drivers, pedestrians, etc...), our design teams have defined optimum features linked to cyclists' visibility. With one purpose in mind: ensuring cyclists' safety.


LED brightness: - front LED light: 75 lumens, 35 lumens in ECO mode - rear LED light: 3 Lumens. Approved for road cycling in France and Germany (STVZO). Equipped with special lenses that focus the light so you can see in FRONT (at a speed of 10 mph) to avoid obstacles and be seen from behind within a 220° range.


3 x AAA front lights (included in the set) 2 x AA rear lights (included in the set) Also compatible with rechargeable batteries. To change the batteries, use a coin to open the rear light. For the front light, simply slide the cover back.

First use

To avoid draining the battery while in storage, the light is shipped with a small plastic tab that separates the batteries from the electronic component. Remember to remove this plastic tab before use. I



Product testing

Lab tests are conducted to validate the bike's components, including batteries, battery life, UV resistance, durability, etc. The final product is then tested to simulate the durability of the assembly over time. The light is fitted to a test bike to reproduce the vibrations of cycling on a road for several thousand cycles.
