This is called the filament. It is what produces light. When voltage is applied it becomes white hot and emits heat and light.
A freesia is a highly scented small spring flower which grows from a bulb.
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
When a bulb is brown the whole bulb would be shaded brown and would be the same shade all over. When a bulb has blown or fused then firstly part of the bulb would be brown the rest of the bulb would be the original colour. Secondly the the internal element that looks like a spring will have broken and roll around inside the bulb.
no gas, bad or disconnected gas line or cracked bulb. Possibly something small blocking the hole inside behind the primer bulb.
Headlight Dipped beam Bulb H7 Headlight Main beam Bulb H1 Requires lots of patience and time as vision and access is restricted. Open the cover of the headlight by undoing the clips.

Remove the two rubber grommets on the inside and, with a flat-blade screwdriver, flick the spring steel catches inside, so that the light unit pops out of its seat, exposing the 18Watt wedge fitting bulb.

Tulips are a spring bulb.
There are three small bolts located around the fog light, assuming you do not have any extra covers, remove the unit by those phillips/hex bolts. There is a small screw for adjusting the light Do not mess with that unless you need to re-aim the light. On the back side of the cover is a twist center (more then likely a grey color) twist this and then inside the opening is a small metal "spring" push down and away from the metal cut out that holds it in place. Then pull out the bulb. Be sure to not get your oils on the new bulb as it could lesson the life of the bulb and or shatter it when it heats up. When you change the bulb and go to put it back into the unit, look at the metal base of where you plug the bulb in, there are two small cut outs which have to line back up correctly!
