Abstract: A compass correction system and method which utilizes data from the vehicle bus, vehicle sensors and vehicle subsystems to determine a compass correction factor.

Abstract: A lighting system that may incorporate LEDs may include any number of features. For example, the lighting system may control dimming of LEDs to more closely match dimming of incandescent lights and/or may control the LEDs by translating the dimming signal received from the vehicle to a signal more appropriate for LEDs. The lighting system may store information relating to a characteristic (e.g. intensity, color, etc.) of the individual light sources and then control the light sources based on the saved information. The lighting system may include a flexible circuit carrying element having a heat dissipating (e.g. aluminum) backing. The lighting system may be configured to control the light sources (e.g. adjust intensity) based on ambient temperature information and/or based on ambient light information.
