Thiesen Electronics GmbH - Pioneer of LED-Aircraft Lights!

EPTA-LSA is discontinued and replaced by the more advanced EPTA-NG

EPTA-LSA - Electronic Positon and Taillight and Anti Collision Light - FAR23

Intelligent Synchronization


Combination of position light, taillight and anti collision light

The EPTA-LSA is the advancement of EPTA and impresses through its enormous higher brightness. The EPTA-LSA exceeds the requirements of FAR 23 by far.

The Thiesen EPTA-LSA will be mounted on the wingtips and is a combination of position light, tail-light and anti-collision light. Similar to the Thiesen EPL shape three aircraft lights are arranged in one position lamp. In addition to the functionality EPL (Electronic Position Light - red / green) it includes a tail-light (EPL Taillight) and an anti-collision light (ACL). The weight of EPTA-LSA is <80 grams.

Again, the built-in ACL in the EPTA-LSA is prepared for the intelligent synchronization.

The EPTA-LSA is embedded together with its integrated entire control element in high-optic, scratchresistant plastic module.

The high-performance LEDs produce a brilliant green and red light.

The wingtip lights are pre-wired for easy connection to a four-wire cable with at least 1.0 mm² conductor cross section. Easy installation by a central screw and additional gluing with silicone. Installation instructions and the shrink tubing required for assembly are included in the EPL.
