I like a lot of the ones that look sort of like an eyebrow. I saw some new car yesterday that had what I'm sure is factory, leds all the way around a headlight with a weird shape. That was fugly.
Let me edit and say that although I sort of like the "eyebrow" look, that doesn't go for older vehicles with round headlights. A VW Bug is what I'd call a "silly car". They are different and tend to look like the old ones, not as much anymore but still you know at a glance if it's a Bug. So with the "silly car" theme, I'd say go ahead and make the lights silly too.
