Welcome to frf as far as your lights as long as they light up red you should be fine. MGL 90/7 states in part: Every motor vehicle and trailer so operated shall be equipped with two rear lights mounted one at each side of the rear of the vehicle so as to show two red lights from behind and a white light so arranged as to illuminate and not obscure the rear number plate and shall be equipped with two stop lights mounted and displayed in a like manner of a type complying with minimum standards for construction and performance as the registrar may prescribe

As long as they light up red you should be fine.
