About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

AARON
LED bicycle light

The LED light set from AARON made a very good impression during testing. It consists of a front light and a rear light, both of which are approved in accordance with the German StVZO. The front light has two light variants (50 & 30 lux), which generate a powerful light output totalling 90 lumens. Both lights ensure increased visibility in road traffic and therefore increase the cyclist’s safety.

The front light is mounted easily and without tools using a rubber band that is wrapped around the handlebars. The rear light is also attached to the seat post with a rubber band.

The AARON bicycle LED light set is characterised by a long service life and is environmentally friendly, as it is supplied in a cardboard box without plastic. AARON is known for its high-quality workmanship and offers fast and communicative customer service as well as a 100% satisfaction or money-back guarantee.

Advantages

✅ Simple attachment
✅ Two lighting modes front light
StVZO approved
✅ Money-back guarantee

Disadvantages

❌ No customer hotline
❌ Description of the front light attachment in the instructions for use and assembly incorrect

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. Of course, adequate protection of the product must also be ensured.

The product packaging

The LED bicycle light from AARONwas delivered in a typical Amazon box. To better protect the product, the cavity was padded with paper. The box was undamaged and easy to open. In this case, the product was fully protected and the LED bike light was therefore in perfect condition.
The product packaging is fully recyclable.
The LED bike light makes a very good impression at first glance.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

*The maximum score is 100 points

After unpacking, the front and rear lights, a handlebar bracket, a rubber tensioner for the rear light and a USB charging cable were on the table. The instruction manual contains additional information on how to use the product, while the assembly instructions contain instructions on how to attach the lights in German and four other languages, although the description of how to attach the front light in the instruction manual and assembly instructions is incorrect.
The contact details are given on the installation instructions and the outer box, unfortunately without a hotline number. This can be found via the QR code in the customer information. Overall, this is a well thought-out and customer-friendly way of shipping a product.

The first time in your hand

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

Fastening and high beam power of the rear lamp

Firstly, it should be mentioned that the bicycle light makes a very good visual impression. There are no recognisable manufacturing defects, unclean edges or corners. The product also impresses with its functional design. The mounting material supplied is also of good quality.
With regard to the sustainability of the product, the manufacturer points to a long service life thanks to the use of high-quality materials.
We also assume that the product will have a long service life due to its good workmanship. In addition, the customer can contact the German company at any time if there are any defects .

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

The LED bike lights from AARON surprised us positively overall.
The brightness of the lights is absolutely sufficient, even in the weaker light version. The battery life is initially at least 4 hours for the front light and approx. 2.5 hours for the rear light. However, this can increase over time, as the LiPo requires several charging processes to develop its full power.
Mounting is simple and versatile, the front light can be quickly and easily attached to the handlebars with the adjustable rubber band, while the rear light can be attached in various places.
The supplied USB cable for charging the batteries is a practical feature. The LED bike light is visually very appealing and functional.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioAppropriate90 points
Rating cut4.3 out of 5.0 on Amazon65 points

Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.3 stars. The fact that the illumination is not so good is often criticised. Many customers like the fact that the LED bike light is easy to install. In our practical test, we were able to confirm that the lighting power is sufficient and that mounting was child’s play.

Prices of up to €39.99 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €19.98. The LED bike light from AARON is currently priced in the upper price segment at €34.95. The price ratio is reasonable for the quality and scope of performance that you get.
