I just put Holley RetroBright LED Headlamps in the Classic White color on my FJ60. This is a great headlight upgrade that will keep your FJ60 looking stock (if that's what you want).
Holley website gives the impression these lights are just plug and play. Well, I found out they are not. But a few extras and you're good to go without modifying your stock wiring harness.
You need:
2 Holley RetroBright headlamps
2 LumaWerx™ H4/9003 Switching Ground Polarity Modules
1 HKP™ Plug-and-Play HID Resistor Harness

How this works:
The headlamp wiring that comes stock on your FJ60 is a "switching ground" system. The RetroBright headlamps are a "switching power" system.
You need the LumaWerx units to convert your stock headlamp sockets from switching ground to switching power.
The next thing is the RetroBright headlamps don't use enough power to tell your FJ60 that the brights are illuminated - so the high beam dash light doesn't work. This is where the resistor harness comes in. Only one is needed to make the dash light work.

Not sure it matters, but I plugged things in using this order and it worked great:
Driver's side: Stock female headlamp connector > resistor > LumaWerx > RetroBright
Passenger side: Stock female headlamp connector > LumaWerx > RetroBright

Done.
 
Holley does say on older Toyotas you need this


I’ve heard an LED bulb fixes the indicator issue
 
I can attest that these are game changers. I went from stock to H4s w a harness to the retrobright. I'd put these on par with my wife's 21 Tahoe.
 
The retrobrites are sooooo good. For my install i just used a simple bosch relay per headlight, but a prebuilt option like this would have been so much easier and i wish i thought of that haha

For the dash, i can confirm that the LED bulb fixes the bulb light. I need to get a dimmer bulb or wire in a large resistor because the led bulb is freaking BRIGHT

Can you send a pic of the set up?

Not sure how well these pictures help but I just did the install. Very easy. The harness comes with two orange female plugs for each new light and one black one to hook into the old harness (also a 3 prong). There are a few ground wires as well. I could probably make my install a little more Pro, maybe someday I will hard mount the relays instead of just using a zip tie but......and I mounted the wire running across to the other light tucked inside the metal right behind the hood latch. I did NOT get the resistor since I use led's in my instrument panel, no need. The led's are great and easy to do, I bought different color leds instead of just relying on the "lens" color of the instrument panel, in some cases I also used a black Sharpie to cover the top diode in the led light since some of them are pretty bright (blinkers especially).
So wire the RED direct to the battery, Orange plugs to the new Holley's, Black into the old harness, in my case, from the passenger side, hook up the grounds wherever you can. Done. You could mount the relays in a different place but would have to extend the red power wire, in any case would have to be fairly close to the battery as the distance between the two new light plugs is not overly long.

I used an LED bulb for the high beam indicator. Works great!
