    Besides a test light if you had a continuity tester could have tested light before throwing your money away if it was good.

    Came across the thread because I was having the same issue on 2015 Pete. Figured out one of headlight relays were bad an also the pin connection on the firewall plug was smashed in. Bent it back out with a pick very carefully an now it's making a solid connection.

    I lost all the headlights on my 387… What am I looking for?
