Lights mounted too low will have problems with irregularities in the
road...casting shadows. This is why headlights are set higher; they shine
down into holes etc. Dangling lights may well become victims of curbs too.
Best mount them above the bumper.

Foglights are best low due to the (usually) clearer air at road-level.
