I understand you have a bulb that you suspect it reverse polarity as you have said
(not sure how this is possible, you would think not- but...)
LED's have anodes and cathodes.
see this article:
http://www.kpsec.freeuk.com/components/led.htm
if the bulb assembly is somehow pre-prepared and is reverse polarity, you have two options:
a. make sure that the entire circut of the lamp assembly really is reversed or not as you fear. it might be good.
if you find it reversed:
1. reverse the polarity of the connections in the socket if you see it possible.
(i dont have one in front of me and this could me a very bad thing so be very carefull)
this could lead to confusion in the future, so proceed with due caution and mark it as such if you find the need (and the actual possibility without a short/open circut)
2. reverse the polarity of the lamp assembly if possible instead of # 1.
