Thiesen Electronics GmbH - Pioneer of LED-Aircraft Lights!

ACL3 is discontinued and replaced by the more advanced ACL3

Einbautubus für Landescheinwerfer (ELL)


The ACL³ is the logical extension of the ACL I which has been in production since 2004.

Like the ACL I, the ACL³ too is made of a high-optic and scratch-resistant plastic module.

By usage of newest LED technologie and better manufacturing technique, we where able to reduce the production costs of our ACL³. This latest technology ensures more luminosity.
As against the conventional ACL the ACL³ emits approx. 100% more light while consuming the same power input.

The entire control element is integrated into the ACL module where the ACL's dimensions determine the required space.

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

The light is prewired to allow easy connection to a 2-lead cable of minimum 1.5 mm² cross section. Flanges allow simple fixture. In addition, it can be affixed to the fuselage or rudders by means of a silicone adhesive. An instructions manual and the shrink tubing required for the assembly are included in the ACL package.
