So, your 2 lights are pulling 15.4 amps. Most light kits have 30amp relays with 20 amp in-line fuses. I'm no expert, but if that's the case, I would think you would be ok. However, if you plan on using the factory wiring/relay/fuse etc....I'm not sure what that set up is rated for. Pretty sure the factory fog lights have less wattage.
Sorry, I'm not really much help.
