This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.

What this guide covers

Estonia is one of the few countries where a pedestrian reflector is a legal duty with a fine attached, and the Finnish rule is close behind, yet almost nothing online says how far a driver actually sees one or how high to hang it.

Pages cover EN 13356 accessory classes, hanging height and swing, EN ISO 20471 vest classes 1-3, reflective tape and wash durability, then the bike side: lux against lumen, beam shape, StVZO K-number approval, the minimum light requirements per country, and dynamo versus battery. ~16 pages, each with a computed "seen from X metres at Y km/h" line.

How to use it

Use Reflectors, bike lights and being seen in the dark to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.

The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Search vocabulary in four languages

Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.

Evidence and provenance

The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.

Source: Liiklusseadus §32 (Riigi Teataja, reusable), Tieliikennelaki (Finlex, free), German StVZO K-number approval register (official), EN 13356 and EN ISO 20471 scope abstracts, published driver detection-distance research (cited); stopping distances computed. · checked 2026-09-09

Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.

Scope and boundaries

This guide owns the explanatory layer for the topic. Personal decisions, diagnoses, legal determinations and live availability remain with the relevant professional or official service.
