Gentlemen, thank you for your comments and quick responses.
Just to clarify, I have 2 standard lights, one on each wing strut on my Jab. These are not real bright, and I only use them for tkof and landing for visibility in poor light and the busy environment I operate in.
They are not used for night landings as I operate day vfr only.
Seems s simple switch change to illuminate both lights at once.
The existing light assembly seems to be a simple “Downlight” arrangement which is exactly what I have seen at Bunnings Aerospace, however I will have a close look and see how I go.
