Taillight
A taillight is a part of a vehicle, illuminating a small area at the back of the vehicle.
Usage
Taillights are used to signify that the vehicle's headlights are on, while also providing small a source of red light. Taillights can be turned on/off by sitting in the driver's seat, and either clicking the "Headlights" icon on the dashboard, or opening the radial menu with V clicking "Turn headlights on/off", noting this will also turn the headlights on/off.
Repairing
To repair, the player needs a light bulb and screwdriver. Remove the old tail light and install the new light bulb in its place.
Condition
Taillights will have a lower effect on the light it illuminates. Depending on the condition, if it is 0, the tallight will not turn on and the vehicle dashboard will glow red.
Trivia
There is no item in the game called taillight. A taillight is only a light bulb which is put in a car. Taking out taillights is a great way to get mechanics XP, as it does not require a specific skill level.
