one or more temperature sensors that detect an ambient temperature around the vehicle; one or more humidity sensors that detect an ambient relative humidity around the vehicle; and one or more proximity sensors that detect if precipitation is present on the lens of the vehicle. ## Claims ### Claim 1 A lamp de-icing system comprising: one or more heating layers configured to heat one or more regions of a lens of a vehicle; one or more temperature sensors that detect an ambient temperature around the vehicle; one or more humidity sensors that detect an ambient relative humidity around the vehicle; and one or more proximity sensors that detect if precipitation is present on the lens of the vehicle. ### Claim 2 (depends on 1) The lamp de-icing system of claim 1, wherein the lamp de-icing system determines if the vehicle is on. ### Claim 3 (depends on 1) The lamp de-icing system of claim 1, further comprising a speed sensor that detects a speed of the vehicle. ### Claim 4 (depends on 1) The lamp de-icing system of claim 1, further comprising a voltage detector to detect a voltage of the vehicle. ### Claim 5 (depends on 1) The lamp de-icing system of claim 1, further comprising a processor that monitors the one or more heating layers, the one or more temperature sensors, the one or more humidity sensors, the one or more proximity sensors, or a combination thereof and controls the lamp de-icing system. ### Claim 6 (depends on 1) The lamp de-icing system of claim 1, wherein the lamp de-icing system prevents precipitation from forming on the lens by heating the lens when the one or more humidity sensors detect the ambient relative humidity being above a predetermined threshold and the one or more temperature sensors detect the ambient temperature being below a predetermined temperature threshold. ### Claim 7 (depends on 6) The lamp de-icing system of claim 6, wherein the lamp de-icing system prevents precipitation from forming while the vehicle is off. ### Claim 8 (depends on 1) The lamp de-icing system of claim 1, wherein the one or more proximity sensors detect precipitation around a region of the lens. ### Claim 9 (depends on 8) The lamp de-icing system of claim 8, wherein the region of the lens is a region that light extends through, a sensor detects through, or both. ### Claim 10 (depends on 1) The lamp de-icing system of claim 1, wherein the lamp de-icing system comprises four discrete heating layers that each heat a different region of the lens of the vehicle. ### Claim 11 A method comprising: a. monitoring one or more temperature sensors and determining an ambient temperature; b. monitoring one or more humidity sensors and determining an ambient relative humidity; c. evaluating the ambient temperature; d. evaluating the ambient relative humidity; e. determining a likelihood that precipitation will form on a lens of a vehicle; and f. activating a lamp de-icing system in communication with a lens of the vehicle if the step of determining determines that it is likely that precipitation will form on the lens of the vehicle. ### Claim 12 (depends on 11) The method of claim 11, further comprising monitoring a status of the vehicle to determine if the vehicle is on. ### Claim 13 (depends on 12) The method of claim 12, further comprising monitoring battery voltage of a battery of the vehicle so that the lens de-icing system does not completely drain the battery while the vehicle is off. ### Claim 14 (depends on 11) The method of claim 11, further comprising a proximity sensor that detects precipitation proximate to one or more regions of the lens of the vehicle. ### Claim 15 (depends on 14) The method of claim 14, wherein the lamp de-icing system is powered with a low amount of power or an intermediate low amount of power when no precipitation is detected. ### Claim 16 (depends on 14) The method of claim 14, wherein the lamp de-icing system is powered with an intermediate high amount of power or a high amount of power when precipitation is detected. ### Claim 17 (depends on 11) The method of claim 11, further comprising detecting a speed of the vehicle when the vehicle is on. ### Claim 18 (depends on 17) The method of claim 17, wherein the lamp de-icing system is powered with an intermediate low amount of power or an intermediate high amount of power when the vehicle is on but not in motion. ### Claim 19 (depends on 17) The method of claim 17, wherein the lamp de-icing system is powered with an intermediate high amount of power or a high amount of power when the vehicle is on and in motion. ### Claim 20 (depends on 11) The method of claim 11, wherein the lamp de-icing system remains off when the ambient temperature is above a predetermined threshold temperature, the ambient relative humidity is below a predetermined threshold relative humidity, or both.
