To create two variants of LED bars using the `workingLightGlass` node and update the `defaultLight` in the vehicle XML file in the lights section, follow these steps:
1. Define the LED bars in your vehicle XML file:
```xml
<lights>
<light name="LEDBar1" active="true" rootNode="vehicle" customEnvironmentMap="true" color="1.0 1.0 1.0" aiEnabled="false">
<visibleNodes>
<visibleNode index="0" name="LEDBar1"/>
</visibleNodes>
</light>
<light name="LEDBar2" active="true" rootNode="vehicle" customEnvironmentMap="true" color="1.0 1.0 1.0" aiEnabled="false">
<visibleNodes>
<visibleNode index="0" name="LEDBar2"/>
</visibleNodes>
</light>
</lights>
```
2. Specify the `workingLightGlass` and `defaultLight` properties for each LED bar in the same XML file:
```xml
<lights>
...
<lightMod name="LEDBar1" type="workingLightGlass" intensity="1.0"/>
<lightMod name="LEDBar1" type="defaultLight" intensity="1.0"/>
<lightMod name="LEDBar2" type="workingLightGlass" intensity="1.0"/>
<lightMod name="LEDBar2" type="defaultLight" intensity="1.0"/>
</lights>
```
By following these steps and adjusting the specifics to match your vehicle XML file structure and LED bar properties, you should be able to create two variants of LED bars using the `workingLightGlass` node and update the `defaultLight` in the vehicle XML file in the lights section.
