  Bi-Color LED for Auxiliary Landing Gear Light Indication & G5 Install

 

Bi-Color LED (Red/Green)

 

Auxiliary Panel Indication of Gear Lights

 

 

 

 

 

 

If you find it difficult to see your gear lights over on the co-pilot side and have yearned for an "in your face" gear light solution, or are doing a panel makeover and would love to add an auxiliary gear light indication, this could be the ticket for your panel. The above is a bi-color LED that will react to the power feed that your existing factory gear lights receive. Obligatory Warning/Disclaimer: This bulb is NOT an FAA/PMA approved component. Nothing in this page supersedes your responsibility, along with your licensed A&P mechanic as to the airworthiness of your selected parts for your certified aircraft.

Simple one hole (0.313" diameter) install into the pilot side panel, fed by the Green and Red power wires of the existing gear lights and a simple ground connection. One bulb with two indications! How cool is that?

 

 

The proper wires that feed the factory gear lights can be identified by looking in your Beechcraft Shop Manual wiring diagram section. The wire ID numbers can be found in the bundle leading to the gear switch and can be seen by an agile person equipped with an LED headlight laying on their back with their head under the co-pilot panel. An appropriate tap into those wires and fed to the red and green sides of the bi-color bulb will result in an auxiliary gear light indication in a place of your choosing.

 

My B55 wiring diagram is shown below as an example of what to look for in YOUR SHOP MANUAL FOR YOUR SN.

 

 

 


 

Below is an example of a Bonanza landing gear wiring diagram - Remember, you must look up the wiring diagram for your specific SN to properly determine how to make your connections. The wiring diagram below does NOT apply to all Bonanza SNs.

 

In the above wiring diagram you can see that the Red and Green lights are fed CONSTANT POWER positive voltage through the LG motor CB. So, this would mean that the circuit for each light is GROUND activated.

I have recently learned that this Bi-Color LED is NOT bi-polar. Meaning that it will not light with a GROUND triggering connection to the red and green wires.

So, if your gear light circuit is of the GROUND triggering type one would need to consider using an appropriate 5-pin voltage relay to accomplish the Green and Red light triggering. A suggested wiring for the relay might look like this:

 

 


 

As with all things in this realm of modification, consult your IA/A&P before proceeding with tapping into your factory gear indicator wiring to add this auxiliary indicator. Some IA/A&P's may simply view this as a logbook entry minor modification and others may not entertain it at all. Your A&P/IA will fill you in on his view.

 

These Bi-Color LED bulbs are available in 12V and 28V versions.

Here are more pics of a G5 install and floating panel refinish project. Note to others, building a ship in a bottle would have been easier, so when you get an eye popping install quote for a G5 install, know that it is very tedious and time consuming work that requires patience and focus to accomplish neatly and correctly. The post light wiring spaghetti was maddening but I tamed the beast with some rewiring and reorganized routings. Work such as this requires an A&P or A&P supervision of your work.

 

 

Re-plumbing the pitot and static instruments was essential since the 50 year old instrument hoses had given every measure of service they could be expected to deliver. This too required very tedious planning and execution in the tight space behind the panel.

 

 

 

 

 

Below is the routing diagram that I created to insure that all went back together correctly. It took five "T" fittings to accomplish the hose routings. 

 

 

In retrospect a manifold fitting (PN: FPM44S) could have been employed to make this plumbing addition much simpler for the numerous static connections .

 

 

Or if you need a 1/8 NPT manifold, HERE below is a 6-port suggestion from Grainger.

 

 


 

The project wouldn't be complete without fresh placards for everything. These were made at my local trophy shop at, in my opinion, reasonable prices.
