This has Method Man written all over it.
Built in cup measuring device on the headlights.
Some may think the yellow lights are fog lights, however they are "shaved" detectors. Once the lady of your choice nears the car they will blink.
If they stay off this means 'BUSH'
Otherwise they will blink as follows:
3 times - 'trimmed'
2 times - 'shaved with landing strip'
Constant flashing - 'bare down there'.
I hope this helps you Methodman
