See whar you mean!., Can be quite dramatic,on a 4 way junction/self- like coronation st Ala transport up here.
Never noticed tint on f/a up here,usually they've got mid-high power an orange/yelliw check on back with normal jammy sand.colours,think they usually run 3-4 pack - Thingscan vary up here mind being mile or so from wheres all money.
