WHELEN 90340 Combination Navigation/Position/Strobe. TSO'd and direct drop in for WHELEN A600 PG/PR units. These have LED green/red/white lights with regular Xenon strobes. Includes HDACF 14v strobe power supply and a never installed LONESTAR "Eliminator" noise filter. Units were operational on Jun 1, 2011 when I removed them and upgraded to full LED units. I couldn't get a photo of the strobe light on since I took the photos with my celphone but they work perfectly. The entire package would cost over $1,100.00 if purchased new at ACS. Asking $520.00 or best offer. PM if interested.
