Trelock LS 660 I-GO Vision

The Trelock LS 660 I-GO Vision is what we'd call the golden middle ground for the serious Dutch cyclist who wants a permanent front light that does everything well. At 100 lux it sits 20 lux above the Sigma Aura 80, and you notice that difference mainly on rural roads without a single street lamp — think the dikes along the IJsselmeer or the Biesbosch. Crucial for the Netherlands: this light carries the StVZO approval, meaning its beam has a sharp horizontal cut-off. It doesn't throw light into oncoming riders' eyes, which the Knog Blinder and Lezyne Lite Drive in this list absolutely do. StVZO originates from the German StraßenVerkehrs-Zulassungs-Ordnung but is widely accepted in the Netherlands and Belgium as the de facto quality mark for permanent bike lighting on public roads.

What truly sets the Trelock apart from the Sigma is the USB-C port — finally a manufacturer who understands we don't want to carry micro-USB cables around in 2026. A full charge takes around 3 hours and gives you up to 20 hours in eco mode, or 5 hours on full power. For Dutch winter conditions — dark from around 4pm to 8am between November and February — that's plenty for a full week of commuting. The IPX5 rating is one notch above the Sigma's IPX4 and handles heavy rain, though it sits below the Knog (IP67) and Lezyne (IPX7).

The lens design produces a strikingly wide, even beam — in practice you see the verges left and right better than with the Sigma, which helps on narrow paths with wildlife. The automatic ambient light sensor dims the lamp under bright streetlights to save battery. One downside: some users report the plastic mounting bracket rattling on cobbles. Easily fixed with a bit of rubber or a zip tie, but not something you'd expect at this price.
