Installing additional wing tip landing lights on a Piper aircraft can increase the pilot's forward visibility when landing in low light or night conditions. Adding two additional lights (one on each wing) adds more forward lighting along with more lateral lighting to see the edges of the landing surface.
When left on during flight, wing tip landing lights increase the likelihood that another aircraft nearby will see your aircraft. In some cases, they can even be wired to alternate on and off between each wing, adding even more visibility. This decreases the likelihood of a mid-air collision.
Installation of these lights must be done or overseen by an FAA authorized maintenance professional. In addition, the installation of these parts must be done with FAA approved parts, FAA approved procedures, and will require either a field inspection from an FAA official or approval for installation under a supplemental type certificate (STC) approved process. This is commonly offered with the purchase of approved parts.
Most wing tip landing lights require some wiring during installation. With the wing tips installed, the maintenance technician will have to run wiring through the wing to a power source and install a switch in the panel of the aircraft for operation of the lights.
Costs to purchase and install wing tip lights on Piper aircraft vary based on the specific product needed and labor rates in the area. Allow between 15 to 25 hours of installation labor time and don't forget the cost of painting the wing tips.
