There are some things that the average car owner can do themselves, but changing headlights, taillights, turn signal bulbs and hazard bulbs may or may not be among them.
Different models of vehicle may have bulbs that are simple to access (like the OP’s), or may require a bit of disassembly and reassembly.
If you want to know the work involved for your particular vehicle, just google it. You’ll almost definitely find detailed step-by-step info, and even video directions for the required work.
