Duh question, High Beam switch...

The manual shows a floor switch, but. I don't see one.

2002 All American RE.

Any ideas please.

I purchased LEd Headlights from Amazon for black Friday and of course the wiring doesn’t match up.

I need to figure out which of the three wires is the High Beam. Low beam is apparent.

Thanks

A “duh” answer…

Use a multimeter, check voltages on the wires.

I had power on the Right side. Didn’t have a solid 0ohm on the Middle wire.
And had nothing on the left wire.
Which I assume was Highbeam.
And Why I wanted to find the High beam switch to check that path.

And yes, I am Electronically challenged.

Real simple, you know which wire is the low beam, turn on the high beams and check the other wires for 12 volts!

3 wires 1 of them is low beam, the other is ground. Last wire must be …..????

Do you have a round barrel type foot switch at the left foot?

and the high beam switch is def not on the column? those floor switches were notorious for getting destroyed by water and road salt.. sometimes the schools would unbolt them and [ut them under the rubber figuring the drivers never need them.. other times they got wired past... on my internationals.. in some years of the late 90s.. foot or turn signal lever was still an option.. so it could be either..

I found the dash switch has 3 positions and 1 is high beam.

The wiring for the inner lamps has 2 wires daisy-chained from the outer Lamp, which has four wires.

the new LED bulbs I purchased are split for both low and High beams.

The PO had swapped out the wiring with black pigtails labeled Made in Taiwan on the outer lamps.

So, I will daisy chain the High Beams to the Inner lamps as well as add new pigtails for three conductors instead of two.

Fun with modes.

Whatever you do, please make sure these are adjusted properly, and don't use them if you can't get the pattern right. Your cheap ones are cheap for a reason, as the reflectors aren't designed correctly and scatter the light, blinding traffic.

Correct ones on low beam should have a horizontal line that is crisp/defined, flat side to side, and is adjusted so that it projects no higher then parallel - aka the mark on the wall is no higher then the light itself. There should be a dot on the headlight indicating the height.

If you can't tell, nothing irritates me more then some handy diy guy putting new led headlights in, bragging about how much better he can see at night, when oncoming traffic needs to wear a welding helmet.

I only brag that I replaced my headlights with incandescents. Becoming more rare so that's what I pride myself on now is classic restoration.

I couldn't use my original brand though, had to go silvaine. They were all I could find today that fit.

My desire is more of a need. The original headlights were rather dim. And I being a newbie, need all the help I can get.

Dash switch is three position toggle

The top shows the Headlight symbol and kicks on the blue dash Light representing the light on, and I assume it's supposed to be the Highbeam indicator.

But its lighting the low beams

Then, the bottom portion of the three positions has a P on it. Parking? Nothing comes on except for the audible beeper in either P Or Light position on the switch.

I ran the wires for the Highbeams to all four of the lamps. But I still can't figure out the High beam. Or if it's wired backwards, Low beam on.

Thoughts, please?

Thanks

One of my favorite things to bitch about, used to carry a bag of pea gravel to toss out the window and attract the idiots attention.

theres so many hosed up LED lights out there... the ones with 3 rows of LED's are the worst.. they just blast light and you cant see well even as the driver with them.. but they are the cheapest and most popular..


the ones I use are like you say a defined cutoff line with very little light spread above that.. with my busses i try to aim them so if I park my regular car about 5-7 feet in front of my bus that I hit the license plate in the middle with the cutoff line.. seems to give me a nice bright area on the road in front of me and not so far that im blasting other drivers..

Have you referenced the wiring diagram for the headlight circuit?

Wires are numbered and color coded, it is real easy to figure out which one is high and low!

On your new lamps, it's is also very easy to do, use a 12v jumper wire and apply power to one pin at a time to figure out which terminal is high and low.

Grab a pencil and paper, make your own diagram as you test each terminal.

You got the tools and resources, now Get r done!

Edit: Confirmed Outer Low beams are supposed to be on all the time according to older thread, and Looking at the Relay collection, there is only a relay for High beams, not low beams.

As usual, you are two steps ahead of me; thank you. That diagram confirms it's my low beams that are not working for some reason.
And means I have to swap the pins out that I installed because they are physically on low on the high beam switch position.

Would You know if the P on the three position light switch is Parking or Low beam?
the center postion seems to be off. And then the HighBeam is the Graphic of the headlight, which coincides with the Blue HighBeam Idiot light on the dash.

But the Lowbeams... and I am starting to think they are supposed to be on all the time but aren't working. And the P is supposed to be the Parking light's position, which also isn't doing anything but beeping at the moment.
