I Agree With Downs Check Grounds To The Core Support To Make It Simple Since You Are Not An Electrical Person
Get A Test Light
Hook To Pos Batt Terminal
Touch To Core Support At Multple Places Ideally Where The Lights Ground
I Think Factory Is Around Driver Fender Front
If It Lights Up You Have An Ok Ground To The Core Support
But After That Stick It Into The Plug Of The Light At The Ground Side If It Lights Up You Have A Good Ground At The Plug
Unhook From Pos Terminal Of Batt And Hook To "hot" Side Of Plug And Stick Other Side Into Ground With Switch On If It Lights Up
You Have Bad Connection At Bulb Or Bad Bulb
If You Had A Ground Fail It Could Have Blown All Your Bulbs At Once Not Common But Could Happen
