LED head lights not working

[storheims]

I bought some LED headlight from Cruiser Corp, put them in no high beam, just low, called them up they sent me another set same thing, my old lights work great got both hign and low beam, have 12.4 volts going to low beam and same when i switch to high. Need some help??? 1982 fj40

I've heard that LandCruiser headlights are wired different from everybody else. Some vendors, like, oh, I don't know, City Racer? Plug and play perfectly.

Polarity is important with LED's. You should be able to test each function with wires. Quality control these days, yea the high beam on both sets could be bad.

Have you tried testing the lights to verify they work.

It would be as easy as running 12+ to one of the side terminals and a ground to middle terminal.

so i just tested the lights with 2 wires from the battery and cant even get the dims to work, plug it back into the head light socket and both dims work, does anyone know how these lights are wired? is it a ground problem?

Is a resistor required?

Toyota flip flops the ground around changing from low to high beam. You need a set of relays to get most to work.

There's kits out there for not much money

am i looking for load resistor for led? do you have any idea whythe dims work?

I'd just hit the easy button, LED headlights don't look right on a 40 anyway.

Here's the best $20 bill you'll spend on a 40 upgrade.

No. You need this.

It works on low because the ground is correct. It doesn't work on high because toyota switches grounds.

I did some more searching and found this diagram which means my original statement about the wiring was incorrect.

Using this information can you retest your lights?

No. You need this.

thank you , I ordered it just now, I only need one right? or two

Covers both sides

you were right, got low and high beams now, thank you!!

Good deal. I like handing out a win.



I'd like somebody at Toyota to explain very slowly to me why their headlight setup is as retarded as it is.

The PO of my 80 series butchered the harness to put in a set of garbage chinesium headlights. They never worked correctly because that relay set wasn't there.

I was starting with 4 bare wires..... it took me probably 2 hours of trying combinations to get high and low to work.
Probably 45 minutes in, I decided that I didn't bring enough tism to do it without a map, so I made a map of every combination of wires.....

Then I replaced the cracked up nightmare of a grill with one from landcruiser grills and installed a set of heated 7" round headlights from Rigid. They're so good I want to put a set in the 40 now.
