84 ranger headlight issue

[chayse brooks]

I have a 1984 ranger when I turn the lights on I have to use my high beams or the lights will not work. After a while of the lights being on the lo beams can work to but they only turn on about 15 minutes after the headlights are turned on. I thought it was the hi lo beam switch causing this but I'm not to sure anyone else having this issue

Have you tried replacing the bulbs?

there is a circuit breaker built into the main headlamp switch which gets twitchy with age,
ant particularly if the hi/lo contacts inside the multifunction (dimmer) switch have become worn.

I recommend replacing BOTH switches

I've personally repaired dash wiring damaged wiring (and near fires) caused by both switches
