So i decided that since i have the Toyota 7 year 100,000 mile warranty i might as well ditch the DRL mod, and leave my headlights always on, since they'll replace them for free! Does anyone actually know the average life span for the Stock headlights or the fog lights? also I just got my runner serviced at 15,000 (i'm now at 15,500) do you think its possible that my TPMS light could come on, I drive normall, dont accel quickly or go on bumpy roads but today after i put about 600lbs in the trunk, my tpms just came on! Do you think my tires are already flat just after the tire fill? or has one of the sensors gone bad?
