D-Light USB Rechargeable Front and Rear Lights

I recently came across these bicycle lights that are small and yet powerful. As they are small and lightweight, they are perfect for use on road bikes. Road bikes will usually only require blinkers, or "to be seen" lights. There is rarely a need for strong lights to light up the road, as most roads in Singapore are well lit at light.

This is the front light, and it is USB rechargeable and so there is no need for expensive button cell batteries.

Very small and yet very bright!

Decent battery life for such a small light. The flashing mode is my usual mode and it can easily last throughout the night if required.

Comes with all the mounting hardware! Velcro strap for helmet mounting, rubber strap for handlebar mounting, and cable ties for everywhere else.

Compact front light, with the button on top. The light is about the size of a small chicken nugget.

Two powerful white LEDs, together with excellent optic lens design creates a very bright light!

Micro USB charging port at the back, sealed by a rubber cover

Mounting bracket for the light. The hooks are for the rubber straps to hook on to.

To attach the light to the bracket, just align the bracket with the light and twist it 90 degrees to lock in the position.

Very lightweight at only 25 grams each, including the bracket and rubber strap.

Different mounting methods as shown in the user manual

The 4 different lighting modes for the front light. This model is CG-211W.

Super bright LEDs makes this front light an amazing light. Small, lightweight, rechargeable and inexpensive, there is nothing bad about this light.

In order not to take up space on the handlebar, the pair of front lights are mounted at either side of the stem spacers. 

Two cable ties plus a rubber shim are used to hold the lights tightly against the stem spacers.

The lights are able to stay in this downward tilting position even over bumpy roads.

Looks like a pair of headlights coming from either side of the head tube. The cable outer casings does not really block the lights.

 View of the front lights from the top. These lights are bright even in the day!

As the centre of mass of the light is near the bracket mounting point, plus the fact that it is so lightweight, these lights are able to maintain the angles as shown even over bumpy ground. The lights will not rotate in their brackets even on rough roads. This rather interesting mounting position is only possible due to the compact size and low weight of these lights.

At the same time, I also got the matching rear light for the Merida Scultura 5000 road bike.

Rear light is also available, with the light oriented in a vertical manner.

Also small sized and super bright like the front light.

Very decent battery life, given the small size of the light. The flashing mode is sufficient for an entire night of riding.

Also comes with all the mounting hardware, for mounting the light anywhere on the bike or helmet.

Power button / mode button located at the middle of the light

Micro USB port located at the bottom of the light, sealed by a rubber cover

Bracket for the rear light. Not quite the same as the front light bracket, as this rear version has a tilted mounting point.

The tilted mounting point ensures that the light points horizontally backwards when mounted on the tilted seatpost.

Very lightweight at only 21 grams inclusive of the bracket and the rubber strap

3 bright red LEDs gives out a very visible pattern that is surprisingly bright for such a small rear light.

Various suggested mounting methods for the rear light

4 modes for this rear light. The model is CG-211R.

Mounted just under the seatpost clamp, and does not take up space on the seat post.

Rear light manages to clear the top of the rear tire for visiblity.

Since this rear light is good enough to be the primary rear light, I have since removed the other Bontrager rear light from the seat post.

These front and rear lights are made in Taiwan and are of good quality. One thing that I like is that the mounting hardware are all provided to cater for all sorts of mounting positions. These mounting methods are also tool free, which means that you can easily remove the light for charging or to move them to another bike, without using any tools at all.

These lights are also very lightweight and compact, which are perfect for mounting on road bikes. USB charging makes these small sized lights more feasible, as there is no need to deal with expensive button batteries that run out rather quickly. If you are looking for some bright, compact and lightweight bicycle lights that are not too expensive, these D-Light front and rear lights are a good choice.


  1. nice setup.. would be great if you can post some night shots showing how much illumination is being projected.. thanks!

    1. These are "to be seen" lights, which mean that they make the rider visible to other people, but do not really project a strong beam to light up the road.

      As such, the brightness can be judged using the pictures above. They are very bright and it is not good to view the lights directly. The lights are bright and visible even in the day, so they will work even better at night.

  2. Hi! Very pleased to come across your article and a very impressive blog too. In the meantime, I am looking at these lights for my mountainbike. What do you reckon about these unusual fitting points being suited for MTB? To the eye, they look somewhat flimsy. I'm aware it all depends on the use, but what would be your personal impression after having seen them in person? Worth giving a try?


    1. The fitting is OK for MTB, as the lights are very small and lightweight, and thus don't exert a large force on the mount. Should not drop off even on bumpy roads.

      However, they are not bright enough to use on night trails. Good as to-be-seen lights when riding to and from the trail, but not in the trail itself as the beam is not strong enough.

  3. Hi, where can i purchase these lights?

    1. You can find them at Rodalink for about $30 each.

  4. How many hours maximum can be charged?
