An adapter device for fitting in a vehicle between a vehicle computer and a computer of a second element integrated in the vehicle for exchanging information between the above. The power supply subsystem further includes a second power supply having a second power circuit, a second controller adapted to control operation of the second power circuit, a second interface adapted to connect the second controller to the external device, and a second bi-directional peer-to-peer port. A second terminal of the NTC resistor is grounded. The first spectral sensitizing dye is an anionic benzimidazole-benzoxazole carbocyanine, the second spectral sensitizing dye is an anionic oxycarbocyanine.
