Narrative:

New pt 139 high speed turnoff lights at echo taxiway from runway 10 are now in compliance with ICAO standards: we now have alternating green and amber taxiway lights that begin on the runway centerline. Amber has been associated with caution. Runway 10 is CAT ii, so now we can have 1200 RVR rollout and see amber for turnoff. I think we should not have amber at least until we are off runway. Additionally, this information is not presented to pilots since pt 139 is not yet written with this information (or available to pilots). Pilots are being put in the position of observing (caution) amber lights to indicate last 2000' of runway, and at dangerous places on the taxiway environment. Now it is on the runway centerline. Should we put on the brakes? Would you educate readers about this change. FAA eastern region is knowledgeable.

Title: AMBER CENTERLINE LIGHTING AT HIGH SPEED TURNOFF CONFUSING TO REPORTER.

Narrative: NEW PT 139 HIGH SPD TURNOFF LIGHTS AT ECHO TXWY FROM RWY 10 ARE NOW IN COMPLIANCE WITH ICAO STANDARDS: WE NOW HAVE ALTERNATING GREEN AND AMBER TXWY LIGHTS THAT BEGIN ON THE RWY CTRLINE. AMBER HAS BEEN ASSOCIATED WITH CAUTION. RWY 10 IS CAT II, SO NOW WE CAN HAVE 1200 RVR ROLLOUT AND SEE AMBER FOR TURNOFF. I THINK WE SHOULD NOT HAVE AMBER AT LEAST UNTIL WE ARE OFF RWY. ADDITIONALLY, THIS INFO IS NOT PRESENTED TO PLTS SINCE PT 139 IS NOT YET WRITTEN WITH THIS INFO (OR AVAILABLE TO PLTS). PLTS ARE BEING PUT IN THE POS OF OBSERVING (CAUTION) AMBER LIGHTS TO INDICATE LAST 2000' OF RWY, AND AT DANGEROUS PLACES ON THE TXWY ENVIRONMENT. NOW IT IS ON THE RWY CTRLINE. SHOULD WE PUT ON THE BRAKES? WOULD YOU EDUCATE READERS ABOUT THIS CHANGE. FAA EASTERN REGION IS KNOWLEDGEABLE.
