a fuse bulb is a bulb in which the filament of the bulb burns and it stops working
A light bulb or a fuse.
It could be either. Check the fuse first, if it is OK then you need to replace the bulb but if the fuse has blown you need to find what has caused it to blow.
If your light bulb is good, then it could be a wiring issue or a fuse issue. A fuse is cheap to replace, so start with that first. If after replacing the fuse, your headlight bulb is still not working, try a good bulb with your adapter. If it doesn't work, then it's wiring issue.
A fuse bulb typically stops glowing due to a break in the filament inside the bulb caused by an electrical overload or surge. When the filament breaks, it creates an open circuit, preventing electricity from flowing through and causing the bulb to stop glowing. Replacing the fuse bulb with a new one is necessary as the broken filament cannot be repaired.
pop your hood and find the what "FUSE PANEL" find the fuse marked Parking lights and replace it. Its that simple. it might not be a fuse have you replaced the bulb or checked your contacts from your wiring?
Somewhere between the fuse and the bulb
If there is just one light out, the bulb probably burnt out and needs to be replaced. A single bulb will not have a fuse.

In a 2000 Oldsmobile Bravada, the fuse for the license plate bulb is located in the fuse box under the dashboard on the driver's side. You'll need to remove the cover to access the fuses. Look for the fuse labeled "LPS" or "License Plate." If the fuse is blown, replacing it should restore functionality to the license plate bulb.
Should be the same fuse for parking/tailights
could be either or, simply replace one bulb to see if that fixes it if not check the fuse
What happens? The bulb lights up when power is applied. Fuses protect the wiring and sockets from excessive current flow. If the wires and socket can handle 13 amps without overheating, then all's good. So, replacing the bulb with a smaller wattage is ok; replacing the fuse with a larger capacity fuse is bad.
