It is not easy to get your fogs work properly.
First of all you have to code your vehicle and shutdown bulb check for fogs. Another story is that your FRM module (ECU which controls also all lights in your vehicle) has some specific settings to limit the voltage on the fog bubls in order to save their long life). You can just install the relay and make many many wires, however you may just make some smart configuration and coding of your vehilce's FRM ECU and push it not to limit the voltage. Standard limit is set for 13.2 volts for the fogs. Once voltage reaches this limit your FRM starts to cut the voltage, thus your HID will start to strobe Many people expiriencing this problem with strobe HID after installation but not many exactly know where to fix it

Regarding the temperature and power - 35W HID kit works perfect in fogs so far, temperature is OK also.
