A filament is a thin thread like part of the plant that holds the anther of the plant. This is the male part of the plant. The anther is what produces the pollen.
anchor or supports anther
The filiment on a plant holds up the anther.
Tungsten.
A filiment in a light bulb is the part that produces the light.
LED instant, Filiment ithin a few cycles, the Fluorescent needs a starter to fire first
You need to change the bulb. The filiment for the brake light part of the bulb is "open" or burned out. The filiment for the tail light portion will still work.
Three Pronged Sealed BeamThose seald beams which have three metal pins [prongs] have TWO filiments inside; one for the low beam filiment and one for the high beam filiment. The third [center] pin serves as the ground for both filiments.
most like the low beam filiment in the right light is bad but the high beam filiment is still good, try replacing bulb. If replacing bulb does not fix problem then you probably have voltage problems and should check the voltage reading and the plug.
Carbon build up on filiment inside sensor. Spray with Mass airflow cleaner or carb cleaner.
Most vehicle rear lamps have TWO light filiments in ONE bulb. One filiment is for the rear tail/parking light function, and the other [usually a larger and brighter burning filiment] is for the brake light function. Therefore, when the headlights are on, the "tail light" filiment should be on. Whether the headlights are on or off, the brake light filiment should come on when the brake pedal is depressed. If this is not happening, suggests one of several possible causes: * The brake light circuit has developed a short or overload which caused the fuse to "blow," * The brake light switch is so far out of adjustment that it cannot function, * A wire has become disconnected [cut, broken, unplugged], * The brake light circuit ground has become disconnected or badly corroded, * The brake light switch is defective.
There is argon in light bulbs so the filiment doesn't does combust. However the gas doesn't come out of the bulb unless you break it.
I x R = E 20 x 6.4 = 128 Volts
White light from a Tungsten filiment lamp is best. If you shine a small ray of the white light in one end a rainbow ray should come out the other.
