highbeams go out????

Any yj owners have the high beams to die or flicker then die but lows work fine? I replaced the dimmer switch in the colum due to recomendations from forum searches. It only does it on long hauls on high beam. Which leads me to believe a heat issue with a relay? I dont know where to start looking? Everything is still stock in that circuit anyways.

Headlight switch. Then search for headlight relay mod. Takes the heat out if the switch because the relays then handle the load. Lights will be a little brighter.

Last easy fix could be the ground wires to the headlight. Terminal end picks up ground off the screw right on the back side if the cans easy to find. Scrape a little paint for the terminal end eyelid to pick up some body for a better ground.

thanks

Its the little things that add up. That switch has been giving me fits forever. I just dont drive far on high beams at a time. It sounds scary lights going out, but driving a homemade , mismatched pile of this will work, that I will replace next week( but still going) kinda gets you expecting the unexpected every once in a while.
Will look into ground connections and relays , thanks......

Sounds like the light switch, mine was doing the same thing. While parked and running turn your lights on and put them on hi-beam. I would be that when they go out if you touch the light switch it will be warm. Replace the switch first, then if you want you can do the mod.

Fixed

Went to attwoods farm supply , bought everything, wire loom(12feet), two 30 amp relays with connectors, two packs 12 gauge wire ( I think 12 feet each), and 2 inline mini fuse links with weather caps for 30 bucks. I ran everything from the battery side. Cut 3 way splices out of the original headlight wires, re-spliced together and ran around behind motor towards battery. Hung my two relays by battery and thats were the old stuff ended . Relays on, had new 12 gauge ran to both headlights from passenger headlight behind grill to drivers headlight. I did test and only had 11 volts to the lights before,key off. I will have to see what its running now. My hot is from the battery post, not alternator like some mods were done. Everything is soldered(?),double shrink tubed, and loomed( cleaned grounds also). Scared me to see the little metal crimped splices wrapped in duck tape in the factory loom. All well ,took me yesterday evenning and finished up this mornning. Broke my fan ground pulling the wires from behind the grill. Which was a good thing . Bad connection got it hot and was going to fall off soon anyway. It got some new 12 gauge wire love also. All in all 30 bucks( minus my shrink tubing, zip ties, and solder) and 4 or 5 hours labor.
I now have brighter headlights( way brighter),and safer headlights, no more (now you see me, now you dont!) games. Untill the relays fail
Thanks to everyone,,,
