Punjabi Truck - All lights and no indicator lights

Went to the Alchemy Festival at the Southbank to see the AR Rahman concert - where the London Philharmonic were performing the music of Rahman. Concert was very disappointing. Outside however, to mark the Southall Stories exhibition was a transport truck from the Punjab, India. These trucks are the pride and joy of their drivers and hugely decorated especially from the Pakistan side of Punjab. One thing they tend to neglect though is the indicator lights.
