66 Mustang Convertible Tail Light Conversion

[SBPJ]

Hi all

Just bought my first mustang and looking for help in relation to converting rear lights so that I have an amber indicator.

Not keen on converting the reverse lights (they are low and barely visible to other drivers)

Also not looking to spend hundreds on LED lights as I will only use the car on the occasional afternoon country drive.

Any ideas or recommendations to get the car through its first MOT, so I can go have some fun.
Many thanks

Dean
