Narrative:
On aug/xa/00 I dispatched a company C402 (xyz) for a night, IFR part 91 repos flight from ZZZ (united states) to martha's vineyard, ma (mvy). During my preflight inspection, I reviewed all outstanding maintenance items in the aircraft flight log. I found 1 item that had been written up and deferred per the company MEL. The deferred item was 1 wingtip strobe light (white) burned out. My preflight inspection found all other aircraft lights (taxi, landing, navigation and the red beacon light) all working normally. Knowing that I had 1 working red anti-collision light and believing I did not need a white anti-collision light (per far 91.205(C)(3) and 91.205(D)(1), I dispatched the aircraft for a night IFR repos flight (without passenger or freight) from ZZZ to mvy. The flight was completed without any incident. The following day (aug/xb/00) I read the specific wording in the company MEL regarding white wingtip strobes and I realized for the first time that the deferment was only good for day operations. This was the first time I was aware of the difference between our company MEL and the far 91.205. I immediately notified company operations and I also notified our company chief pilot when he returned from vacation on aug/xe/00.
