# Customizing maps: Traffic Lights and Signs
|
|
|
|
This guide explains how to add traffic lights and signs to your custom map, configure the area of influence of each one, and how to configure traffic lights as a group at junctions. This option is only available to users who have access to the Unreal Engine editor.

## Traffic lights
|
|
|
|
To add traffic lights to your new map:
|
|
|
|
__1.__ From the _Content Browser_, navigate to `Content/Carla/Static/TrafficLight/StreetLights_01`. You will find several different traffic light blueprints to choose from.
|
|
|
|
__2.__ Drag the traffic lights into the scene and position them in the desired location. Press the space bar on your keyboard to toggle between positioning, rotation, and scaling tools.
|
|
|
|
__3.__ Adjust the [`trigger volume`][triggerlink] for each traffic light by selecting the _BoxTrigger_ component in the _Details_ panel and adjusting the values in the _Transform_ section. This will determine the traffic light's area of influence.
|
|
|
|
>>
|
|
|
|
__4.__ For junctions, drag the `BP_TrafficLightGroup` actor into the level. Assign all the traffic lights in the junction to the traffic light group by adding them to the _Traffic Lights_ array in the _Details_ panel.
|
|
|
|
>>
|
|
|
|
__5.__ Traffic light timing is only configurable through the Python API. See the documentation [here](core_actors.md#traffic-signs-and-traffic-lights) for more information.

## Traffic signs
|
|
|
|
To add traffic lights to your new map:
|
|
|
|
__1.__ From the _Content Browser_, navigate to `Content/Carla/Static/TrafficSign`. You will find several different traffic light blueprints to choose from.
|
|
|
|
__2.__ Drag the traffic lights into the scene and position them in the desired location. Press the space bar on your keyboard to toggle between positioning, rotation, and scaling tools.
|
|
|
|
__3.__ Adjust the [`trigger volume`][triggerlink] for each traffic sign by selecting the _BoxTrigger_ component in the _Details_ panel and adjusting the values in the _Transform_ section. This will determine the traffic light's area of influence. Not all traffic signs have a trigger volume. Those that do, include the yield, stop and speed limit signs.

## Next steps
|
|
|
|
Continue customizing your map using the tools and guides below:
|
|
|
|
- [Implement sub-levels in your map.](tuto_M_custom_layers.md)
|
|
- [Add buildings with the procedural building tool.](tuto_M_custom_buildings.md)
|
|
- [Customize the road with the road painter tool.](tuto_M_custom_road_painter.md)
|
|
- [Customize the weather](tuto_M_custom_weather_landscape.md#weather-customization)
|
|
- [Customize the landscape with serial meshes.](tuto_M_custom_weather_landscape.md#add-serial-meshes)
|
|
|
|
Once you have finished with the customization, you can [generate the pedestrian navigation information](tuto_M_generate_pedestrian_navigation.md).
