This is a DIY (do it yourself) LED display replacement for King KX155 and KX165 NAV/COM radios.

If you own a KX155 or KX165 radio that has a dying display and needs a new replacement display, this LED display will be your answer as the original “glass” display is no longer manufactured.

Unlike the original “glass”display, this LED display uses LED technology which involves no high voltage driver, no gas-discharge lighting or eventual leaking-gas issues. The LED display functions just like the original – it automatically dims at night time operation and brightens up on daylight for maximum visibility.

DIY installation involves absolutely no modifications to your KX 155 165 radios. All you have to do is pull the old display out from its socket, and slide the new LED display into its place. And then connect the two power wires (long red wire and a short black with ring connector) to correct locations.

DIY installation itself is simple enough – it should not take more than 30 min for most people.

The installation is completely reversible – this means that you can always pull the new LED display out and put the original “glass” display back in the radio in case you are having issues with TSO or any other.

For installation, you will need a soldering iron, solder, 3/16 nut driver, phillips screw driver

More detail installation procedure is available on YouTube. Search for “Replace KX155 KX165 display” on YouTube. (Ebay does not let me put a direct link on the listing.)

Please note Ebay will require signature confirmation at delivery.

The KX155 radio in the picture is NOT included in sale – it is for demonstration purpose only.

                                                                    CAUTION

If your KX155 or 165 has a display issue, this does not always mean a bad display and needs to be replaced. It could be internal display drive circuitry or something others causing the issue. In this case, the LED display won’t do any good. Make sure your KX155 165 has no other issues but the display itself.

                                                                    CAUTION

This LED display is custom designed and has not been through any FAA certifications. It is mainly intended for experimental, none-airborne radios and some private aircraft owners and individuals who want to exercise ownership and would like to work on their own aircraft.  If you would like to install it in a registered aircraft, we strongly suggest you check with proper authority first.
