i had this issue with my halos... if they packed ur lights in the really squishy foam, take some of that and put it under the bumper skin where the head light sits. this helped alone by itself. but then i took my lights out and wrapped electrical tape all around the plastic clips that hold the light to the bracket... pop them all way out. mine popped out easy... wrap that piece 2 or 3 times in tape, put the piece back in then wrap the the plastic piece and where it clips into the bracket with as much tape as u want. mine turned out good and u cant really see the tape when lights are installed. i have no bounce at all even when i hit bad bumps in the road.
