Claim 0:
1. A heating system for an LED vehicle lamp having a housing and a lens, comprising:
a circuit board positioned within the housing;
at least one LED mounted to the circuit board;
a heating element mounted to the circuit board, wherein the heating element comprises at least two resistors configured to heat the lens from within the housing;
at least two temperature sensors mounted to the circuit board, wherein the at least two temperature sensors include at least one temperature sensor positioned proximal to the heating element and at least one temperature sensor positioned distal to the heating element; and
a microcontroller in communication with the resistors and the temperature sensors, and having stored thereon computer-executable instructions which, when executed, cause the microcontroller to regulate voltage sent to the resistors based on incoming voltage, ambient temperature, and internal temperature of the housing,
wherein the microcontroller is configured to monitor readings from the at least two temperature sensors and determine the ambient temperature based on the readings.
