in a single circuit hookup. Car 2710 was tried out simply with additional lighting fixtures along the sides, and car 2006 (ex-2500) with the revised circuitry for brighter lighting. The decision was made to use the revised circuitry and also add a single light fixture in the corner opposite the motorman's cab. This latter was tried out on eight cars prior to rebuilding – 2060, 2184, 2333–4, 2354-5-6, 2618. The wiring used for these cars was defective and resulted in numerous fires, far more than with other types of cars. At the ends of the cars, the cross seating was removed between the outer set of side doors and the car ends, leaving only the side seats in their place. On the test cars (2119, 2396-7-8, 2482-4041-2483), this was done only at the blind, non-operating ends, but eventually, the cars that were rebuilt received this at all ends. A speckled green interior paint was applied to these cars. There was a sample car (2654) for the first 8 that went into service (2472 (ex-2771)-4036-2473 (ex-2753), 2588-9-90, 2693, 2743), and for the remainder, which were painted on the interior further up toward the roof line, there was a sample car (2675) for this as well. Around this time, car 2851 had one set of center doors painted over on its lower panes. The first 8-car train of sample cars went into Brighton Express service in March 1959. With the shifting of equipment concurrent with service changes two months later, the train was moved to Sea Beach Express service. Soon afterward, the train was broken up and was freely mixed with other A/B Standards, as were cars that were later rebuilt. Rebuilt and unrebuilt cars were freely mixed in consists henceforth. Headlights were added to the rebuilt cars beginning in 1962, when the rebuilding program was about complete. In anticipation of this installation, two cars were modified to have only one running light fixture: 2060 and 2743. Car 2709 never received headlights altogether; ironically, it was one of the cars scrapped when some of these cars were substituted on the scrap list for those to be preserved for the museum. 15 of the 2800 series cars (5 units) remained in Coney Island Yard for 2 years after their service ended. No move was made to save any of them for the museum. Beginning in 1956, the exterior painted on numbers were supplanted
