Converting to LED indicators is one of the most common modifications for supermoto and enduro bikes. At the same time, there's a lot of uncertainty: Are LED indicators legal? Are resistors required? Are there differences between Austria and Germany?

In this article, we explain the most important basics – factually, understandably, and without technical jargon.

E-marking for LED indicators

LED turn signals for road use must have an **E-mark (E-stamp)**. This marking indicates that the turn signal has been tested according to a European ECE regulation.
Important: The E-mark must be embossed directly on the casing, not just on an accompanying document.

LED indicators front and rear – differences

Generally, similar rules apply to front and rear turn signals:
- correct mounting location
- prescribed minimum distance
- Visibility from different angles

Correct installation determines whether the turn signal is legal for road use.

Flashing frequency and resistances

LED turn signals require significantly less power than incandescent bulbs. Without suitable resistors, the flashing frequency can become too fast.
This can be objected to during inspections.
Therefore: use the correct resistors or a suitable relay.

Differences between Austria and Germany

The basics are based on European ECE regulations.
- National testing practices may vary
Individual inspections may be necessary.
- If in doubt: ask a specialist workshop or testing center

Common mistakes during renovation

- missing or invisible E-marking
- incorrect spacing between the turn signals
- no resistors installed
- messy wiring
- Off-road turn signals in road traffic

Conclusion

LED indicators are a popular upgrade when correctly selected and fitted.
- E-mark directly on the turn signal
- correct assembly
- correct blink frequency
- professional installation
