@franklin40 & @Spook50 I threw in a 50ohm resister this morning. I won't be able to say for sure until it get dark tonight, but it look about the same brightness as the brake and CEL light next to them.

Yeah a resistor alone won't dim the LED as long as the voltage matches its operating voltage and the current available is equal to or more than it pulls. You'd need a PWM to "dim" it. A better option if you want to keep an LED in the indicator would be to find one with a lower lumen output, which is what I might do. The primary reason the resistor is used in the first place is to prevent blowing the fuses when you toggle high beams by pulling the stalk back. If you have an incandescent bulb in the dash, you could dim THAT by changing resistor values. I can't remember if the socket uses a 194 or a 168 bulb. They're the same dimensionally, but the 168 bulb is brighter and draws more current (also as a consequence, hotter). If the original design was for a 168 bulb, I would try a 194 bulb instead to see how you like it.50ohms ended up not being enough. Still got blinded with the LED high beam indicator whenever I turned the high beams on. I ordered some 100ohm resistors and apparently misplaced them. So I soldered two 50ohm resistors back to back. Reduces the amps down to 0.13A oppose to 0.23A with just one 50ohm resistor. The dash indicator still comes on, so I'll report back to let you guys know how it turns out.
Being that the LED bulb only draws 0.01A I'm not sure I'll see a difference. If this doesn't work I'll give up and go back to incandescent
74 LED Bulb - 3 SMD LED - Miniature Wedge Base - Blue
LED replacement bulbs can fit numerous vehicle applications such as vanity lights, dome lights, map lights, dashboard lights, instrument panel lights and gauge lights. This 74 bulb replaces a variety of traditional bulbs including 74, 103 and 118 bulbs. It has 3 LEDs (3528 SMD)—1 top-mounted and...www.superbrightleds.com
Well, a resistor worked. I messed around with bulb on my test bench power generator. At 14v unrestricited the LED pulls 0.019Amps. Swap over to constant current and reduced the amps until I found the brightness level i thought was about right, which was 0.003amps. Did the math to double check the superbrightleds specs and the LED has about 74ohm of resistance on it own. But anyways I end up ordering a 4K Ohm resistor from Mouser electronics. Threw it in today and it’s prefect. No more blinding myself with the hi beam indicator.Yeah a resistor alone won't dim the LED as long as the voltage matches its operating voltage and the current available is equal to or more than it pulls.

I stand corrected. Looks like I need to church myself up on LED circuits again.Well, a resistor worked. I messed around with bulb on my test bench power generator.

Yeah the bulb in question has a pretty generous volt spread, it's advertised as 10-16VDC. But with my test bench power supply on constant current the light was working all the way down to around 8.3 volts.i know there are dimmable LED bulbs now. And LEDs definitely have an on/off voltage threshold with minimal output difference regardless of applied voltage unlike an incandescent. But I know from personal experience that my LED headlamp light output does vary with the amount of charge remaining in its batteries. Still I think it’s a pretty small range of light output to voltage drop as compared to the older filament bulbs.
Yeah, that's what had gotten me was the availability of dimmable bulbs. Ironic that I have dimmable bulbs all over my housei know there are dimmable LED bulbs now.

But I know from personal experience that my LED headlamp light output does vary with the amount of charge remaining in its batteries.

I want to thank all of you, I used all the information here to create what a was looking for. I really wanted leds but I don’t like the look of them on the fj62 I think it just doesn’t go together, so I went with holley retrobright they look very similar to factory making a much nice light on my opinion, then a wanted all 4 light on low beam on and all 4 on high beam on as well, I was worry that was going to be too much for the one high beam plug to handle so I went with two relay’s one controlled by positive to control the low beam for all 4 lights making a crossover wire and one controlled by ground for the high beam same as the other with a wire going to the other side to control all 4 lights with just two relay’s. I got all the signal from the passenger side high beam since is closest to the battery and all the wiring is made on 12ga wire that should be plenty. Today I might start messing with the high been indicator.

yes sure, I will get you some pics of the wiring tomorrow.Congrats! looks fantastic!. I am about to order sets for me and a client. Can you please share some photos of the wires behind please.
yep @kelly saad !
i did the led dash light swap thing but found the 4wd and the high beam indicator to be way too bright at night so went back to incandescent for those.
Can you post the pictures of your wiring??I want to thank all of you, I used all the information here to create what a was looking for.
