LOW MINS LOW VISIBILITY LNDG BY MDT ACR ACFT -- HIT RWY LIGHTS.

Narrative

I WAS THE PF FOR A NORMAL NIGHT ILS WITH LOW CEILINGS (100 AGL) AND LOW VISIBILITY (1 1/2). THE ILS WAS ESTABLISHED AT THE CORRECT AIRSPD AND FLAP SETTING. I WAS ABLE TO MAINTAIN THE LOC AND GS DOWN TO MINS OF 200 FT AGL + 1/2 MI VISIBILITY. THE PROBLEM BEGAN WHEN I TRIED TO TRANSITION FROM INST FLT TO NIGHT VFR WITH FOG. I NEVER GAINED ANY DEPTH PERCEPTION OR OUTSIDE REFS; AND THE RWY WAS WASHED OUT BY A MIXTURE OF THE FOG WITH THE RWY LIGHTS ON HIGH INTENSITY. WITHOUT ANY VISUAL REFS; I BEGAN TO DRIFT TO THE R OF THE CENTERLINE AT APPROX 150 FT AGL. THE CAPT SAID; 'MY ACFT' AND TOOK CTL OF THE ACFT. IN DOING SO; HE CORRECTED TO THE L BRINGING US TO THE L OF THE CENTERLINE. AFTER TOUCHDOWN; OUR L MAIN GEAR LEFT THE RWY STRIKING 2 RWY LIGHTS. HE WAS ABLE TO LAND NORMALLY AND BRING THE ACFT BACK TO THE CENTER OF THE RWY WITH LITTLE EFFORT. THE CONTRIBUTING FACTORS IN THIS SITUATION WERE: LATE NIGHT FLT; FOG; LOW CEILING; HIGH INTENSITY LIGHTS COMBINED WITH FOG; THE PLT UNABLE TO TRANSITION FROM NIGHT INST FLYING TO NIGHT VISUAL FLYING IN CLOSE PROX TO THE GND. IN ORDER TO PREVENT THIS FROM HAPPENING IN THE FUTURE; THE PLTS SHOULD BE TRAINED TO TRANSFER CTL OF THE ACFT TO THE PLT WHO HAS BEEN ADAPTED TO OUTSIDE REFS TO COMPLETE THE APCH WHEN THE WX IS DOWN TO MINS.
