I'm not being funny but....
I can see the bulb in the headlight chamber working during the day, but surely at night it will be a problem? Average headlight bulb is 55w, the brightest indicator is still only 21w.
It would be really difficult to tell if you are indicating a night, esp as I'm guessing the light would follow the reflector pattern of the headlight, so truckers might be a big problem.
Last thing we would want is Bellend getting killed isn't it?
People who have done the smooth bumper/vento front before have put ultra bright LED strips in the outer corners of the headlight, and they look subtle, couldn't see them unless your looking for them.
At least in this position they would be more visible at night.
Alternatively, if you could find a way to dim the headlight when indicating like Audi's do their running lights, that would look pretty sweet!
