Narrative:

Lbg tower advised traffic on opp heading. Type and altitude unknown. I did not see the small aircraft Y due to nose high climb out attitude and light haze. When I finally saw small aircraft Y, the pilot had already made a steep descending turn to his left to avoid collision. Pilot and apparently was operating in the air traffic area (and within 10 NM of lax) west/O a mode C transponder.
