Am absolutely satisfied with the set. The searchlight is with 20 Lux very bright and the way often lit very well aus.Fahre at 4:30 clock in part on unlit cycle paths to work and had been in the dark large Probleme.Hatte quite a few bicycle lamps ausprobiert.Sowohl cheap (CA20, -) , as well as expensive (CA80, -) or the original Dynamobeleuchtung.Aber the Sigma lamp is so far not approved the beste.Ob or interests me'm nicht.Ich prefer well-functioning, non-approved battery lights on the road, as with a non-working but approved dynamo lighting. This is also the opinion of many law enforcement officers. Conclusion: Very good illumination of the road, good workmanship, easy installation and Demontage.Absolute buy recommendation.
