Flashing rear light with brake light
The BUSTER RL 150 ensures that no one will ever overlook any cyclists who uses it! SIGM´s brightest rear light has 150 lumens and a visibility range of 2,000 meters, offering maximum visibility. Cyclists can be better seen on the road or in the woods from a long way off. The practical brake light function signals each braking operation, ensuring additional safety in road traffic.

Five light modes, including flashing modes, are available, and provide up to 20 hours of light. Durable, compact, lightweight, and mounted without tools – the perfect rear light for the toughest requirements.

HIGHLIGHTS:
- Versatility thanks to five light modes
Cyclists can choose from five different modes to customize luminosity and battery life. In High mode, the BUSTER RL 150 can operate at 40 lumens for up to four hours; in Low mode, at 5 lumens for up to 20 hours. The Day Flash with its two pulsing red LEDs and 150 lumens lasts for six hours, drawing attention to the cyclist. In Night Flashing mode at 25 lumens, the rear light can continue flashing for up to seven hours. For longer rides, the Eco Flash mode provides additional visibility and safety in road traffic for up to 20 hours.

-Brake light for more safety
The integrated acceleration sensor ensures that the BUSTER RL 150 detects a braking operation right away. The two LEDs become especially bright in this situation for about three seconds. This practical feature ensures more safety – not only at night, but also during daytime rides in road traffic or during a group ride.

- Get started quickly thanks to the memory function
The memory function ensures that the BUSTER RL 150 always switches back on in the mode that it was in when it was switched off. This makes it easy for anyone to get started quickly.

- All-round visibility
The BUSTER RL 150 ensures that cyclists are easy to see even from the side. It is equipped with side apertures that ensure that the rear light can be seen at an angle of 280 degrees. This is an important safety feature, especially in city traffic.

SPECIFICATIONS:
- Three-level battery indicator
A short press on the operating button, and the three-level battery indicator shows you how much power your BUSTER RL 150 still has. This allows bikers to switch to a more economical lighting mode when they need to and ensure that they have enough power finish every last mile of their tour.

- Switch-on protection (double click)
The BUSTER RL 150 is switched on with a double-click. The big power button is easy to operate, even if the rider has gloves on. This lets the rear light be stowed in a jersey or backpack without any trouble and without inadvertently switching it back on.

- Powerful, but conserves resources
The BUSTER RL 150 has an integrated lithium ion battery and is recharged via the USB-C port. The rear light takes no more than three hours to charge completely.This not only eliminates tiresome battery changes, but also conserves resources, making the light more sustainable.

- Tool-free mounting
Thanks to the silicone strap, the BUSTER RL 150 can be mounted on seat posts of up to 35 mm diameter in a matter of seconds, no tools required.

- Splash-proof
The BUSTER RL 150 is splash-proof according to IPX 4, so it can be used in inclement weather conditions.

FEATURES:
- 2,000 m visibility range
- Two-LED brake light function
- Five light modes: High, Low, Day Flashing, Night Flashing, and Eco Flashing
- Burn time: 4 h in High mode (40 lumens), 20 h in Low mode (5 lumens), 6 h in Day Flashing mode (150 lumens), up to 7 h in Night Flashing mode (25 lumens), 20 h in Eco Flashing mode (5 lumens)
- Charge period: 3 h
- Tool-free mounting with silicone strap
- Integrated USB-C charge function
- 280-degree side visibility
- Three-level battery/charge status indicator
- Switch-on protection (double-click for ON)
- Splash-proof in accordance with IPX4
- Weight: 25 g

Sigma buster rl150 rear light black 150 lumens

2025/02/09

Vital

This is a really bright flashlight in its maximum modes. An interesting autostop function - when the flashlight recognizes slowing down and turns on a kind of brake light - it shines even brighter and without blinking. Not the easiest control, but you can get used to it. Convenient charging from type C. The battery is definitely enough even for a very long ride, and I don’t need more - I just charge it before the next time.

Satisfying

2025/01/30

Clearly visible, numerous operating options, offers brake light function at a reasonable cost. One star less because it shows some uncertainty in the operation of the switch/selector.

Very light and really powerful. All modes are good. Easy to mount and stays in place. Unbeatable value for money. Super sensitive brake warning light. Much better than a Gadget radar rear investigator that beeps all the time and doesn't light up much.

Various types of flash. It emits a light in its maximum position that is not enviable to other brands or more expensive lights. Fast charging. Although a bit bulky, it is lightweight and fits discreetly under the saddle. Happy with the purchase.

Good light, compact and light, with the day mode it sends a super powerful flash that is perfectly visible during the day and at night it is even too powerful. The other night modes are all very good and allow you to manage the battery as each one has a different consumption. I recommend it

Very good rear light

2024/10/04

Murgelp

Very bright and easy to see. I only use the brake light mode, which works excellently. It actually lights up when you brake, and not when there is a shock. However, the light only lasts 4-5 hours in this mode, not 20 as stated. The battery LED also only lights up yellow when there is only 30 minutes of battery left. So it loses one star.

Good daylight light

2024/08/24

Colin

This light seems to be good, so far. All the different modes work 5 in total. There are 3 battery charge indicators (green 100%, yellow 85-25% and red from 25%). There is also has a brake light, which does work, but whether anyone pays attention to it is another question. The light is a good size and fits neatly behind the seatpost, which is a D shaped aero on mine. I can highly recommend this light.

Good product

Igor

Excellent light. Visible at all times of the day and night and from a great distance. I didn't test it on longer drives, but it worked for 4 hours without any problems. I recommend. The USB c port was important to me because I use a Garmin edge 1040 and a newer version of a smart phone, so I don't need a bunch of cables when traveling.

Happy!

2024/06/13

Great. Purchased for my son, and compared to other cheaper ones, nothing to see. The brake sensor works very well, and lasts in that mode for about 4-5 hours.

The lamp is really great, all modes work. There are 3 battery charge indicators (green 100%, yellow 85-25% and red from 25%). It also has a stop system when the bike stops. The light is really not large and fits perfectly into the seatposts, whether 30.9 mm or 27.2 mm. I highly recommend the sigma product

Santiago

Light with very good visibility. Even better than Bontrager's Flare. To name its flaws, I would say that the anchoring system is worse since it does not come on and off as easily as the Bontrager one and is somewhat more cumbersome. In any case, it is worth it if what you want is visibility

I think words are unnecessary, it is spectacular. I had always had pilots of mediocre quality... Of course Sigma is quality and reliability... Light 10 Quality 10 Performance 10. What I said is 100% recommended.

As always, Sigma products do not disappoint. The quality and functionality are spectacular. The light is powerful and very visible from a long distance. If the person behind you can't see you, it's because they're wearing wooden glasses. 100% recommended

Good taillight in itself, shines really brightly in the bright or flashing settings. Only the brake light works a bit strangely, it sometimes switches on while driving even though you don't brake. Therefore only 4 out of 5 stars.

Great

MIGUEL ANGEL

Of all the devices used to date it is the best, great lighting and braking detail, although a little short on battery

Excellent, visible and efficient

2023/10/21

Alban

I recommend it to those around me: it has the perfect lighting modes to be seen clearly during the day and at night (without dazzling other users, the intensity fluctuates continuously without flashing too erratically), and the "fire" function stop" works very well! It can also be attached to your bike with a clamp if you fear having it stolen.

Jose Luis Garcia

This is the second lamp that I buy for myself, but all the colleagues who go out to shoot with me have liked it a lot, since it is very visible in the day so it gives more security. So up to now I have bought 3 additional ones. Something also that I liked a lot is the detection of braking and the price.
