Layer is the perfect blend of cutting-edge technology and minimalist design.
With its die-cast aluminum frame and compact, intuitive shape, the turn signal seamlessly adapts to any motorcycle style, from naked to touring, highlighting and enhancing its personality.
The suspended-eﬀect light body creates a striking visual balance, brought to life by a modular micro-pattern lens. This refined detail not only boosts luminous intensity but also gives the front end a bold, unmistakable identity. Inside, years of experience and engineering excellence converge: the 8 SMD LEDs deliver a sequential light eﬀect, oﬀering exceptional visibility while maintaining an ultra-compact shape.
The design is completed by a rear cover with a dedicated x-shaped pattern and a mounting system equipped with impact-dampening technology, developed to ensure long-lasting durability, reliability and performance.
Layer turn signal complies with European homologation standards.

Technical information

Kit is composed by: (2x) Layer sequential lighting turn signals, (2x) washer and fastening nut kit, (2x) turn signal thread cap.
Use of the very latest SMD LED technology ensures compliance with European homologation standards.
Functions: TURN SIGNAL (12 V / 1.5 W / 8 LED)
M8 THREAD
To fit the turn signals, the wiring kit is required.

When replacing OEM turn signals with the Rizoma Layer, with sequential flashing, to avoid incompatibility due to the resistors and the OEM electronic control unit, Rizoma always recommends the substitution of four Layer turn signals, two in front position and two for the rear (excluding cases where the turn signals are integrated in the front optical unit, in the rear-view mirror or in the front fairing).

Homologation and certification

This product is certified compliant. To know whether a product is certified compliant, just check for the presence of the letter E immediately followed by a number enclosed in a circle.

What are the electrical specifications?

12 V / 1.5 W / 8 LED

Which lighting technology is used?

SMD LED Technology (Surface-Mounted-Device).

What advantages are there to fitting SMD LED indicators?

Compared to normal bulbs, LEDs last longer, are brighter and take up less space.

What is the significance of fitting indicators in either series or parallel?

An 'in series' connection is when two or more components are connected so that they make up a single route for the electrical current to pass through; if the components have two poles (i.e. are bi-polar), an 'in series' connection requires that one end of each component is connected only to one end of another, with the current flowing in through the free terminal on the first bi-polar component and out through the free terminal on the last bi-polar component. (see diagram 2 in the assembly instructions) - An 'in parallel' connection, on the other hand, is when the components are connected to a pair of conductors so that the electrical voltage is applied equally to all of the components. To understand this better, here's an example with two people: two people are standing between two ropes which are stretched out and parallel to each other. Each of the two people is holding one of the ropes in each hand so that both are holding the same rope with the right hand and the same rope with the left hand.

I only fitted 2 Rizoma turn signals on my motorcycle but they don't flash correctly. How do I fix this problem?

On motorcycles tested by our R&D department, we always fit four turn signals (where possible). We recommend that you seek advice from a specialist workshop or use resistors to adjust the current.

My motorcycle is fitted with LED turn signals as standard. Do I need to use resistors when fitting Rizoma turn signals?

No, these are not generally used.

My bike, as OEM equipment, has two-function front turn signals (front position light and turn signal). By mounting the Rizoma Layer turn signal, the double function still works?

No, by mounting the Layer turn signal the position light function will be lost, Layer has the turn signal with sequential lighting function only.

SUSPENDED DESIGN, ESSENTIAL STYLE

The suspended light body and clean lines enhance the motorcycle’s geometry with balance and lightness.
Die-cast aluminum and a modular micro-pattern lens define a precise, refined aesthetic that merges strength and sophistication.

COMPACT TECHNOLOGY, ENDURING RELIABILITY

Eight high-performance SMD LEDs deliver a smooth, highly visible sequential turn signal in one compact unit.

An impact-dampening mount and a rear cover with an X-pattern ensure long-term durability, safety, and compliance with European homologation standards.
