I installed these Bat Overlays for my headlights and foglights.
I chose the light smoke shade.
Various shades and colors are available.
He has them available for:
Headlights
Foglights
Cargo Lamp
Tailights (Smoke Full)
Tailights (Smoke with reverse lamp cutout)
Tailights (Smoke reverse lamp only)
I chose this shade for a subtle look.
Also, it's difficult to capture a good picture of it.
They are definitely more noticeable in person and they do not compromise visibility at night.
