Narrative:

While flying at 1800' MSL tracking inbound on the srq localizer one mile outside of outer marker on a visual approach to runway 32, a twin engine light aircraft went by my aircraft approximately 100' below and 100' to my right side at a 135 degree angle. This aircraft was reported at 1700' by jacksonville center before we switched to tpa approach control. Before talking to tpa approach, that aircraft was west of the localizer and paralleling outbound. Tpa within asked, informed me that it was outside his airspace and VFR so perfectly legal. The light twin's pilot used extremely poor judgement in not talking to approach while flying through a localizer 100' below glide slope intercept altitude.
