What does Light Control Module Do in Cars?
The Light Control Module Designed for Fire safety reason and security embeded system assist and to prevent battery discharge in case any light left on or shorted connections caused by other factors.They also supply B-plus to almost half dozen "CAN" based operating System Control boards in their sleeping modes, such as anti-theft module, remote lock or starter ,windshield wippers Timer board,and few other board. since most of the system assisted by this module actually use only few miliamps of current for bianary codes and Communication with the logic board therefore there is not much electrical stress on the components ,the only exception is when high current is used in driving Mode which puts lots of stress on the components and after a 6 or 7 years and in this case 9 0r 10 years later the Modules Fails.

The Head Lights ,the instrument illumination , the dome light ,the Front Yellow Parking Light (corner Lights), The Turn Signal Lights and Pulse,The Back Night Marker Lights ,This lights show a car in Front in Roads in Dark of the night,This Light is one of the most Failed one by this LCM in LincolnTown car (the problem is that if you drive one of this model year ,you will not notice if you back marker lights are on in the nights or not) but since the source for this light and License Plate light and Front Yellow Parking lights are same circuit in this LCM and these 3 lights will not be working in case you LCM is bad ,then all you have to check to see if you Front corner lights are on or not ,if so the other 2 are also off ,then you know the module is the problem and should be repaired or replaced with a rebuild one , a used one from another car may work ,but this problem will show up sooner or later unless the module is rebuilt and Boosted up and says boosted up in their repairs.when this module is rebuilt and boosted up it will last 3 times the original which is about 21 to 25 years .
