2024/10/14

goncalo

The Sigma Blaze Flash rear light is without a doubt, the best bang for the buck investment in bike lights.... It has all the features that a main rear light require, whether it´s the visibility and a long lasting battery, but it´s added modes really make it a standout among other lights. The Brake Mode is very helpful in city traffic and also when riding in a pack, since it´s constant glow is better for the human eye to measure the distance to a moving object. The Eco Pulse, with it´s longevity close to 50h, it´s perfect as a main/second rear light for ultras, providing all night protection for 4/5 full nights, without recharge. Very happy with this purchase!

My favourite rear light

2024/08/02

Tobias

The SIGMA Blaze Flash is definitely my favourite rear light. The break light function is fantastic and the set-up is super easy. I have one for each of my bikes, but you could easily just have one and move it between bikes as needed. It would only take a couple of seconds to do so. It is light weight and slim, fitting perfectly behind the seat post. Battery life is good and charging is fast and no hassle at all. Changing between the different modes is easy, even though I mostly just use the Auto mode. On VERY long rides or if bikepacking I would probably switch to the Eco Flashing mode, which gives a 50 h run time. Sure, it doesn´t have a radar or camera, but that would put it in a completely different product (& price) category. I miss none of those features.

Nuno Afonso

Excellent lamp. Works as described, battery life does not disappoint. The operating modes are top notch. The braking system works perfectly, in less than a second the system detects braking and activates the light. The light is quite visible, both night and day. The finishes appear to be of quality. It's difficult to find a better price-quality ratio, TOP.

Lovely!

Highly recommended! The housing takes the inclination of the seat post into account - which makes it very visible. Very bright, with the switchable flashing modes it's actually impossible to miss - very bright! Also has a brake light function. A real recommendation for the price!

The flashlight is of good quality, the only drawback is its fixing tape, they could improve the system. After 2 months of use, when I took the headlight off to charge it, it already broke. I'm very careful about the details, even so it exploded.

2023/11/13

Andres

Amazing rear light. It has all the functions I need and more. It has a very reliable construction and materials, and super well designed (compensated angle for the seatpost is key. It points directly at traffic). Brightness is more than enough for a rear light and with the two different flash functions you´re not only seen but calls attention in the traffic. The brake sensor makes it super safe and works great. It turns on with almost the slightest deceleration. Can´t think of anything to be improved, much less at this price point. Really great purchase and now looking to replace my OEM front light for a Sigma product.

Does it fit an Aero model seat post?

2024/10/12

Deivid

Does it fit an Aero model seat post?

Answer of Alejandro

Good afternoon, yes it fits, my seat post is oval and fits perfectly. It is true that it is not held firmly, it can withstand bumps and wind, but if you rub it a little when you grab something or try to touch it, it twists.

Answer of Erik

It comes with a spare rubber clamp that is slightly larger than the one I use for a classic 27.2 seatpost.

Road Traffic Regulations

2024/03/28

Stefan

Hello, does the rear light have STVO approval? Since it has a flashing function, greetings Stefan

Answer of Bostjan

I did not get this information from Sigma. Since Sigma is German product i do belive that they get the approval, certification. Best regards.

Answer of Adalberto

In the explanatory material for the sigma light it says nothing about this German transit certification

BATTERY and fixing

2023/11/06

Wanderley

How does it charge the battery, which connector? Does the cable come with the product? How is the fixation? Clips? Screw? In the bank?

Answer of Adrián

The one I have has the small USB plug. Bring the cable, not the charger. I use the phone charger. The fixation is with a support and a rubber band. It is robust and does not fall. It is anchored to the seat post and is easy to put on and take off. I am content. The battery lasts a long time and lights up well. I use it on MTB for the parts of the route that cross roads. As an extra, when braking the light stays on, like the car.

Lumens it emits?

2023/10/16

Daniel

I wanted to know how many lumens or luxes it emits in the different modes.

Answer of Bostjan

This is really a well spend money. AUTOMATIC LIGHT SENSOR: VISIBILITY ≤ 500 M. BATTERY LIFE ≤ 9 Hrs. MANUAL PERMANENT LIGHTING MODE: VISIBILITY ≤ 500 M. BATTERY LIFE ≤ 9 Hrs. PRESS FLASH: VISIBILITY ≤ 500 M. BATTERY LIFE ≤ 11 Hrs. ECOFLASH: VISIBILITY ≤ 500 M. BATTERY LIFE ≤ 50 Hrs. BRAKE LIGHT: VISIBILITY ≤ 1500 M. BATTERY LIFE ≤ 3 S.

Answer of Adrián

I´ve had one for a year or so. I don´t know how many lumens it emits but on the most powerful setting, it emits quite a few, enough to be seen. I use it in the mountains for road sections and the truth is, it gets to me. I am happy.

Flashing

2023/07/07

Frank

I bought Sigma rear light model 115150. While cycling, only 1 of the 3 lights are on. Does this have a flashing function?

Answer of Adrián

In theory, by pressing the button, it changes function. There are several flashing modes that change each time you press the button, plus it goes into "brake" mode when stopped.
