so my back right side marker and back taillight (far right one only) are out and i knw nothing about lighting and this electrical stuff. Do i just have to replace the bulb or could it be a wiring issue?? Any steps that i can see to find out whts wrong with them. Car is about 2years old. Like i said i knw nothing about this stuff but i knw people on here do, so any help would be great. Is it pretty easy to replace the bulbs or? tx ahead of time guys and any help would be great.
