And if they are one sided, the amber should face the REAR. I got into a heated discussion with another member about this- he put his facing the front. WHY? you already have the composite lights facing the front, they were to provide someone coming alongside with a signal indication, why do you need two to the front. His answer was they just wanted them higher. Uh, they are already 4-5 ft off the ground! you don't see mini coopers with turnsignals on sticks...
He drug me down to his level and beat me with experience. And I was dumb enough to let it happen, so I deserved it.
