LED Dome light reading bulb help

About to pull my hair out on this one. The original bulb in the dome light with reading option is a GE 1004. It is a dual contact BA15D bulb. I ordered a LED equivalent bulb. When I plug it in, the light comes on. When I switch the reading light off, it stays on. My question is; are the original 1004 bulb bottom contacts + - or ++. The LED bulb is ++. Do I need a +- LED bulb? Thanks!!
