How do the Audi A4 lights work?

Does anyone know how these lights work; http://www.carpages.co.uk/audi/audi_imag鈥?/a>



Are they all little bulbs or just a tube, I am just asking maintainability wise.



Thanks.How do the Audi A4 lights work?Just a row of LED lamps. Not a tube.

All the car companies are doing it now. It saves lots of power which can be used to power things like navigation systems and all that sort of sh1.



From a point of view of maintainence you can assume that Audi will only sell a whole module containing all the LEDs rather than you being able to change a single LED.How do the Audi A4 lights work?Yes, they come as a complete strip of little diodes. It's not beyond the bounds of possibility to replace one individual diode if your're handy electronically and can source a replacement, but not in the normal run of things.
