Next I noticed:
* It provides a 50-meter-long, bright lanes wide carpet of light, in addition to a somewhat weaker near-field in front of the front wheel.
* Leichtweiß bluish light color.
* Lights gigantic much brighter than my previous, simpler headlights. But this may also be because the Dynamo is at this bike at the rear and the lower power consumption of the LED, the voltage on the long road ahead can not fall as much as a light bulb. This is a subjective impression, but it seems like the proverbial difference between night and day.
* The spotlight does not fit the usual standard sheet metal holder, which makes necessary the use of the own holder. But this is worth it, because this is very stable.
* Rather unobtrusive design, the risk of theft is possibly less than a model with a futuristic look.
* The case seems durable, is well made, the rotary switch (on / off) also feels stable.
* No automatic switch
* Parking Light Function: missing, it should not forego actually, because that can be really useful and important.
In this price range the Trelock is a good choice.
