    Although some lighting technicians try to please their clients by instituting a quick and competitive repair by installing similar lighting system components that were immediately available in their service vehicle, it's not advisable. The quick fix has often turned into a long running warranty feud when the original equipment manufacturer's replacement products are not used. In addition, there is no way to confirm that the lighting system is still ETL compliant. It was the FAA's position that aviation obstruction lighting systems that have been serviced using non-original equipment manufacturers' parts are no longer in compliance with FAA specifications of FCC regulations. However, on November 12, 2004 the FAA announced that it was setting up a policy for non-OEM parts manufacturers so that they could certify their products. The FAA has stated that further public input and further study by the agency was necessary to assess the adequacy of existing guidance in FAA advisory circulars pertaining to obstruction lighting, and the need for any changes in such guidance. The deadline for offering comments was January 11, 2005, although later remarks might be considered depending upon their relevancy.

    If the equipment is under warranty, use OEM. If it is out of warranty other companies have parts for units that have been independently certified as meeting FAA criteria.

    Recent experiences with one company would indicate certain regions of the universe would freeze over before parts would arrive in a timely manner. Don't' get me started on RMA's.

    Best guidance is use what is designed for the gear. Controllers no longer supported by manufacturers use parts which meet or exceed electrical specs, voltage, amps, breakdown voltage and the like. Transistors, IC's and relays are usually available from other places.
