I was digging thru the socket boxes at the parts store and we came up with a 1157 metal insert.The old 1156 metal insert pushed out of the plastic housing and the 1157 one slides right in.I just had to cut the tab off the top so it can slide in but no changes to the socket or housing.$3 each socket with heavy wires.Now I need to get the swtichback bulbs and the right relay for LEDs to flash right.How many LEDs can fit in the housing??45-60-120??I want the brightest I can fit in.I will post pictures of the socket once I get it done.I did find an LED bulb with a projector 7watt.Supposed to be brighter.
