Flickering Headlights 74 Bronco
Hey Guys new to FTE any help would be appreciated. Got two trucks with the same problem. After roughly 15 min headlights start flickering on and off? Any solution ideas?

Power to the headlights goes through the headlight switch and is kicking on (and off) the headlight relay.
One solution is to simply replace the headlight switch... BUT a better solution is to install relays sourcing voltage directly from the battery and use the headlight switch signal to energize the relays.
You can buy or build a harness. LMC has 'em for $30 or here's a wiring diagram:

But if the OP simply posted a question in this here FTE without doing a modicum of homework, then that would simply be super lame.
