OEM Aux Clearance Lights

@Coolerman and others... I don't know how I missed it ... But... There was a discussion about these lights in the 25 area

So were all good, if I purchase some wiring it won't catch my vehicle on fire and burn to the ground.

All good my friend! Just tell me what you need and I will take care of you.

I knew this had to have been discussed before. You found too many pics of them for someone not to have noticed this earlier!

The next question is how did they function? If they are clearance lights, they both are on at the same time? On with headlights? On with park lights only?
The reference in that other thread about Green/Orange wire on one of them is a clue. On earlier trucks that color was used for the left turn signal only. Green/Yellow for the right turn. If they are clearance lights why would Toyota use turn signal wire colors?

I also noticed that the wire exited the harness at the headlight socket. I have worked on many harnesses, including one from Australia, and none of them had that wire...

only commented because I may be able to figure out which part book/year it came from. You have done with the lit what I wished I could have done

Rewrote my post above... ALOT of stuff is your ... We owe ya ... Big time

I can only find information pointing to 5/73-2/74... I can only find examples from Australia ... I believe they may have been used in Europe as well ... As they were also in some markets the ones that got the larger directionals in 74' a year before us

European cruisers got some funky things ... Fender skirts... Edge guards on corners... Weird spare hubcaps

Interesting. It looks like these may have been used when the early bib lights were phased out in some markets, so probably on with park lights/side marker lights as were bib lights.
The parts diagram makes it look like they mixed up the larger fog light and the clearance light with the way the wire harnesses are drawn/labelled. But to my eye it looks like clearance light harness taps in by the right fender marker light at a 4th connector not present on the left side, drops down as a single wire and splits off at the right front light following the inside of the bumper to the left side light. So that would mean the extra wire in the other thread shown from the left side headlight may not be related.

That other thread was also a BJ series not an FJ. The Fog Lights on a BJ are built into the harness, not a separate harness as the drawing I posted earlier shows. Here is the BJ schematic. It actually show the Fog Light Circuit complete.
Note that the Fog Lights will not come on unless the headlight switch is on. Doesn't matter if it's low or high beam.

I wonder what the requirements were for the multiple world markets regarding the clear marker lights.

Follow me here, early 40's had simple round turn signals and tail lights. In the US, the multiple reflectors were added to the sides of the body to meet DOT requirements and probably other countries for markers when the vehicle was parked. Go forward, the round turn signals became rectangular, the side marker lights were integrated into the body with reflective lenses and a rear reflector integrated near the tail light. This arrangement made for orange front and side markers. Now early models had the clear markers low in the bib. Go to late 74/75 and you get the larger front turn signals with integrated reflective side marker, orange turn signal and clear marker light all in one. Of course this was easier and cheaper to produce than two or three separate lights.

Another similar sequence, since an FJ55 was shown earlier with the little markers, they too used all the same variations of turn signals and changes to the front markers. Now jump ahead, an FJ60 also has separate orange colored turn signals and clear front marker lights. I'm sure this trend is found on other Toyota vehicles found around the world.

Soooo, what was the reason for the clear front marker lights? I have never seen it on a US domestic vehicle, all older Chevy's Fords, etc have orange front markers. Why did Toyota have clear markers until the late 80's. I see these little add on clear lights as a stop gap for certain markets when the first rectangular turn signals came out, and there was no longer a clear marker light on the front of the truck. But again, why did some places require a clear marker light. Obviously US DOT accepted it for that time period as a catch all in their regs, but what was the requirement of other countries.

For instance, Subarus have had a separate switch that turns on their marker lights only, because in some European countries as I understand it, they are required to leave on the marker lights when parked at night???? so perhaps clear markers were a similar requirement in some places.

If you want some good reading about lighting check this out: http://en.wikipedia.org/wiki/Automotive_lighting

This article describes world wide lighting requirements going back to the VERY beginning when oil lamps were used!

It even describes the semaphores called trafficators that were used on the early FJ25's.

To answer your question about using clear lights on the front.

"Front position lamps", known as "parking lamps" or "parking lights" in the US and Canada, and "front sidelights" in British English provide nighttime standing-vehicle conspicuity.They were designed to use little electricity, so they could be left on for periods of time while parked. Despite the UK term, these are not the same as the side marker lights described below.

The front position lamps may emit white or amber light in the United States and Canada; elsewhere in the world they must emit only white light. Colloquial city light terminology for front position lamps derives from the practice, formerly adhered to in cities like Moscow, London and Paris, of driving at night in built-up areas using these low-intensity lights rather than headlamps."

So Toyota park lights emitted white light as that is what the rest of the world used...

Well there you go, I'd say the little lights were an interim step to fulfill the requirements of certain markets.
