I bought these sylvania super whites $24 a piece... had no problems for a year then my head light went out,, i wiggled the plug and it went back on, it continued to go on and off over the next couple weeks.. Now i cant keep the damn lights to stay on, i have replaced the OEM bulbs and no difference... i need new plugs.. i do spell light electrical burn when i smell the plug and the plastic looks as though it has bubbled.... any ideas?
