ACL4 - Electronic Anti Collision Light

Brand New ACL4
with FLARM-Interface and Intelligent Synchronization


ACL4 - for fuselage or vertical stabilizer installation

The technology carries on - so we developed the new ACL4 for you. With LEDs of the newest generation we were able to boost the brightness of about 50%. Simultneously we reduced the power consumption remarkably. This makes an efficiency enhancement of about 100%!

As a matter of course all our LED position lights / ACLs are water and seawater resistent. Since the electronic parts are completely integrated in the ACL4, no black box or other items are needed.

Like all our other ACLs, the ACL4 is completely sealed in high grade optic plastic. As all electronic components are in the ACL4 integrated, there is no additional place needed.

The extremely bright, red sequencing light flash has a beacon angle of 360° and is visible at 30° below and above the horizontal plane.

For easy connection, the ACL is already provided with a 1,5/0,25 mm² four-wire-cable. It can be installed on the fuselage or vertical stabilizer by its flange footing and some additional silicone.


As worlds first we integrated a FLARM-Interface in an anti collision light for motorized aircraft in order to increase the visibility and therefore the safety in the airspace. The by the Power-FLARM unit provided signals increase the light pulses and therefore rises the attentiveness.

See how it works

Intelligent Synchronization

The integration of our well proven Intelligent Synchronization allowes a chronological sequence of power consumption for the connected anti collision lights and prevents battery and generator from becoming overloaded.
