Sigma Aura 80 USB vs Trelock LS 660 I-GO Vision
Comparison 2026 — Bike Lights
Our verdict
The Trelock LS 660 I-GO Vision wins 82 to 78, a small but honest gap that reflects one thing: extra brightness and premium materials cost money. Both lights are StVZO-approved — essential for legal use in the Netherlands and Belgium — but how they deliver that light differs. The Sigma Aura 80 offers 80 lux from a compact 73 g package at €34.95 with up to 15 hours of runtime in eco mode. The Trelock LS 660 I-GO Vision delivers 100 lux (25% more light), weighs 95 g, has USB-C instead of micro-USB, includes an automatic brightness sensor, and is made in Germany with a 3-year warranty. For a €15 premium you get noticeably more light and a future-proof charging port. On brightness the Trelock scores 86 vs 76, on battery life 84 vs 74. Only on value for money does the Sigma win, 92 vs 76.
The Trelock's even beam pattern — thanks to a specific lens design — is a real benefit on dark unlit bike paths, since you don't see dark spots ahead of you. On lit city streets the gap narrows and the Sigma's 80 lux is perfectly adequate.
For most commuters we recommend the Sigma Aura 80, unless you regularly ride unlit rural paths or USB-C is a must — in those cases the Trelock LS 660 I-GO Vision is the better long-term investment.
Trelock LS 660 I-GO Vision
The Trelock LS 660 I-GO Vision wins with 100 lux (25% more than Sigma's 80 lux), USB-C instead of micro-USB, and an automatic brightness sensor that makes a real difference on unlit paths.
Sigma Aura 80 USB
The Sigma Aura 80 is €15 cheaper, 22 g lighter, and delivers 80 lux of StVZO-approved light that's more than enough for 90% of Dutch urban cyclists.
