It is my understanding that the lights are actually LED's Dakster. At least the indicator lights are. We usually get our IPC's from ISSPRO out of Seattle, WA. I have tried to disassmeble the IPC before, but no luck. Don't forget, 2003 and newer need to be programmed by you GM dealer. The IPC needs to know what kind of vehicle it is in and what kind of options the vehicle as well as having the VIN programmed into it.
