Hello everyone I'm new to the Kia scene,I just picked up a 2001 Sportage 4x4 5spd.I was wondering if anyone knows what the 2 red lights on the bottom of the rear bumper are for.i thought they were reflectors but when I pulled the lenses off there's 1157 bulbs in there I replaced them with new bulbs and they don't light up.I tried brake,hazard,turn, headlights and even backup but no luck.Anyone have any ideas? Thanks
