Has anyone used the headlight conversion from Bronco graveyard
I used your headlight conversion along with the Heavy Duty Headlight Harness, part #24800H ,But my high beam light indicator on dash,, when you switch to high beams it comes on just for a second an goes right back out , it just wont stay lit up when put on high beams, ,, . Now the headlights do work as they should from high to low beams, just the blue light on dash for high bean indicator light will not stay lit, it flashes on when you push the floor switch for high beam but goes right back out , even though the headlights themselves do work on high an low beams as they should
Has anyone had this issue ?
I've never had good beam pattern from that type of light (clear lens, fluted reflector) but I know the designs have come up in the world over the last few years. How's yours in that regard?
But I can't imagine how any change in headlights has any effect whatsoever on the high-beam indicator in the dash. Seems to me that's an issue with the wiring between the foot switch and the dash.
Did you also add relays to the mix, or just the lights?
I still don't see how relays would effect the indicator in the dash either, but wondering for the record if there were other changes.
Curious if the relays take their switching signal from the passenger side, and the indicator gets it's power from the driver's side circuit, if perhaps you need to re-ground the driver's side old plug.
But this would only be if you added relays too.
But check/jiggle the wiring all through the harness anyway.
I'll check my diagrams for '79 to see if anything obvious sticks out.

The kit came with the relays and its a nice a clean looking hookup , thing is I can unhook there harness an use the original and high beam indicator works normally , I emailed Bronco graveyard and there tech has never seen this issue , Only thing is there new harness plugs in only to one of the original headlight plugs and then there harness jumps across to the passenger headlight ,,the original passenger side headlight plug is not used , unsure if that's an issue or not,,cant answer yet on headlight pattern as I have not had the chance to check as its a work in progress ,,also if I plug headlights up with the original headlight plugs and leave the new harness out of the equation the high beam indicator works normally,,the grounds are clean an hooked up but will double check that first chance ,, its weird it comes on when you press the foot switch but goes out immediately after it switches
Yes it is weird! But a fun new gremlin to track down and figure out too!
Sorry you've got to live through it though.
So it goes back to working whether you only disconnect the harness, or only the lights?
Or did you just say that you leave the lights alone and only change which way they get their power? If so, maybe it is the relay harness after all.
You do say that the highs and lows work, but have you looked at the pattern (on a wall for example) to be sure that you actually are getting the high-beam out of the lights? I think you sounded pretty clear about that, but I'm trying to make sure so as not to overlook something.
Just for giggles, and because it's easy to do, try swapping the two relays for each other. Just flip flop them to see if anything changes.

Yeah high lows seem to work fine, I plan on checking that again to make sure but I feel pretty confident that that part is fine , since I can still hook to old plugs I will check both ways but it might be next weekend as I have work scheduled this weekend , I will try switching relays but uncertain of that outcome ,but we will see,,I did mis speak as its hooked up on battery side which is passenger side , so original driver side plug is not used, perhaps I need to reverse that setup ?
We installed the relays from LMC using OEM sealed round bulbs and our hook up was the same. Connect relay harness on pass. side, run drivers side wiring behind the grill to its bulb. mounted our relays on pass. side.
Everything works as it should.
I don't really have any suggestions other than to say that it seems your relay hooks up the same.
If I do not use the new harness at all, and just plug in the headlights to existing factory hookup , then the high beam indicator will work normally , that's what is throwing me off at the moment , lights work with new harness as they should , just high beam indicator light comes on with foot dimmer switch for a second , then goes out , so I do plan on checking to make sure the headlights stay on high but when I press the dimmer switch the last time , the high beams appeared to have stayed on high reflecting off my garage door but I do want to double check that , it doesn't make sense , bulb in dash is new but I may pull it again an double check the connection but since it works with the original wiring I am lost , its probably something very obvious that I am overlooking lol , but I am almost tempted to make my own harness with relays and try that
Are you using the harness that has the option to have the high and low stay beam BOTH stay on when on high? Maybe that is the issue?
I don't think so ,,and there tech couldn't tell me whats causing it at Bronco graveyard
description below states relays do control high an low beams , has to be something I am over looking , I walked out and turned on headlights and high beams are working an dim properly, but high beam indicator on dash still flashes only for a second when switching Upgrade your headlight's wiring harness for maximum light output with a Heavy-Duty head- light harness. If you are adding brighter bulbs or upgrading to high power halogen lights. then you need to improve your wiring to take full advantage of the extra light output. This Heavy-Duty Harness is complete with separate relays for low and high beams and features OE-style headlight sockets for easy installation with no splicing or cutting required. This is recommended for use with our headlight part numbers 24800, 24800A, and 24801. 1978, 1979 Ford Bronco 1973, 1974, 1975, 1976, 1977, 1978, 1979, Ford F100, F150, F250, F350
the relays supplied are garbage though. Mine last maybe 1 yr.
btw if the harness is causing you grief just run the headlights only. I did harness first and then later did headlights. The harness was not a noticeable improvement like the headlights were.
my 40yr old truck has better headlights than my wife’s 2015 expedition.

Yeah I thought about using only headlights but like the idea of relays for safety reasons , I have only just starting to tune things an work out kinks as its been a project past couple years , still have to finish the bed for the build and paint it , I did notice once that when I started the truck that the ALT light came on while reving the the engine but went out at idle,(only did this once) , now today it did not do this , so I think perhaps I need to check alternator as its not new , wiring harness is in good shape , and I do need to ground areas better but most are hooked up , engine block to frame is hooked up but need to run some more body grounds to frame
Might as well check battery voltage while you're at all this testing. Off and running both. Should be approx. 12 to 13 volts, depending on how long before that the engine had been running. If it's been sitting awhile since last charged, 12.3 to 12.6 volts. When running you should see 14.5v approx. even with all the accessories running amuck.
Not sure that the relay harness enhances safety, per sé. But it makes sure that the lights are getting full system voltage rather than a somewhat lesser value.
If the rest of your wiring is in great shape, your lights should still work fine without them.
I installed relays in both my Bronco and F350 probably 30 years ago now. Neither had anything like what you're experiencing.
The high-beam indicator lamp is powered by the right headlamp circuit. As another test, try disconnecting only one or the other headlight.
So disconnect the driver's side lamp and turn on the high-beams. Then re-connect it and do the same test with the passenger side. See if it makes any difference either way.
