Re: LED headlights and taillights

Three prong flashers provide a separate connection for an indicator light. Many times a two prong and a three prong work equally well in a circuit that you are building. The most important consideration for switching to LED's is usually to make sure you get an electronic flasher rather than an old style load based flasher.
