This is the most known part and it must be very accurate.
This board has been designed starting from one my personal need: read the labels Auto Cruise, Normal Cruise, Pursuit without seeing the light source underneath.
The eccessive led power leaded to an ugly light effect which made the labels unreadable in most cases.
Since the boards have been developed starting from 0, the leds that have been used can be power controlled so you can reduce the light and have the labels clearly readable without seeing the SMD leds source light
The board has also 4 holes studied to be finely fixed to your dash.
