Default Illuminating cornering lamp assemblies

1998 -1999- 2000 North American LS400's employ cornering lamp assemblies without lamps.

Meanwhile, offshore variants depict a cornering lamp assembly that incorporates bulb and sockets.

Am interested in removing front side marker lamps (large ugly orange peels), refinishing the holes away and running stock wiring down to the cornering lamps...(it reaches)
Anyone know the correct Toyota P.N.s for the bulbed lamp assemblies and can recommend an offshore vendor. (other than Amayama (PayPal) and PartSouq-(who can't give you the time of day without a serial number)

Cornering lamp assembly

Backside of cornering lamp assembly is blank. Considered fabricating a hole with correct indexing slots for a socket assembly. It is unclear whether interior is reflectorized.


No ugly orange peel side marker lamp on front bumper cover of 1998 Celsior. Overseas versions placed it rear of front tire in middle of fender. I intend to reposition side marker wiring to the cornering lamp and use a high output amber LED lamp.

Here are the Japan market part numbers for the 2000 Celsior:

LAMP ASSY, CORNERING, RH 81360-50010
LAMP ASSY, CORNERING, LH 81390-50011
BULB, CORNERING LAMP 90981-13043 12V 21W
SOCKET & WIRE, CORNERING LAMP 90075-99128

The corning lamps on the Japanese market 1998-2000 LS400 throw out a lot of light to make it easier to see while turning. They do not function as side marker lights. The parts appear to be more readily available now to U.S. customers than they were when I tried to get them in the early 2000's. Googling the part numbers should find them for you.

If you want to just convert the existing dummy light modules to additional side marker lights, there was a thread on this forum many years ago about how to drill a hole in the back and install a low wattage bulb socket that plugs in and is held in place by little springs on the socket. There is not much clearance in the dummy lights for a bulb but the person who did it found that a small 5W bulb fit OK. The Japan market corning light units are much deeper to allow for the larger 21W bulbs.

The orange lamp module in the fender in your photo is not a side marker light - it's a turn signal that lights up only when signaling a turn. I bought similar side turn signals in the U.K. and had a local body shop install them on my 1990 LS400 shortly after I purchased it new.

I have a set imported from Japan that at some point I’ll install and wire them to the corners with a timer relay to keep them on when blinkers are trigger and stay one for a period of time after the blinkers are off. Also why were talking about the fog assemblies, jdm units have a yellow glass lens in their fogs. I brought over a set of those as well and with 3000k hids, I get a deep yellow output vs pale yellow that usdm units have.

Can you post images of your parts?

Through the "lense" of the North Amercan version, the turn signal lamp assembly resides next to the headlamp.

Are there two turn signal lenses each on left and right front half of 1998 - 2000 JDM Celsior?


1998 1999 2000 North American LS400 turn signal lenses..




The side marker lense are a dowdy afterthought so am contemplating indexing J-slot holes in the stock cornering lense blanks and using the side marker lense LED bulb that I had custom made.

The orange peel holes would then be professionally filled and refinished....unless of course anyone can locate a set of JDM Fog and side marker lenses.

For anyone looking to retain stock side marker lense configuration, but improve appearance ...scroll to the end of post for write-up on 8 chip Amber LED's :

The front turn signals on the 1998-2000 JDM Celsior are exactly the same as on the North American 1998-2000 LS400 - same part numbers. A benefit of the your "orange peel" front side markers us that they have reflective properties. The 1998-2000 Celsior did not have front side marker lighhts.

I'm not understanding why the orange front side markers are bugging you. They serve a useful purpose.

From a technical or aesthetics standpoint?

First, they appear to me to be an afterthought...not integrated, raised instead of flush.
Light uniformity is poor- hot spots. ..check out my link for critique and solutions applied;

https://www.clublexus.com/forums/ls-1st-and-2nd-gen-1990-2000/874861-side-marker-lenses-improving-color-uniformity.html





Better aesthetics without the orange peel on the bumper...


Lense with stock incandescent bulb. Yuck.


Incandescent bulb at night with amber silikrome light color filter/diffuser

8 chip Dr. LED amber LED lamp at night. Quite bright. Aluminum foil added to orange peel to improve reflectivity over gray plastic lamp socket pocket.

I would cut a hole and glue in a socket. I've done this to other cars including my Camry Wagon. The center portion didn't have illumination adding a bulb makes it light up just the rest.

I used a socket from some random Toyota at a salvage yard think it was a mid 90's Corolla.

I'll snap some pics some time this week. Below is an old photo I had on hand of the fogs. Left side is JDM fogs and right is USDM with glare shield removed, both with the same 3000K hids. Photo isn't the best representation of the color, but it shows how much yellower the JDM ones are. Also USDM fogs without the glare shield does put out a lot more light, but it is very uncontrolled and scattered.

Default Flush integration of side marker lense in front bumper

Located an image depicting front side marker lense of 2001-2006 IS.
The lense nestles in a pocket flush with the front number cover.
So I see the IS lense and wonder why more seamless integration not used on 1998-2000 LS400.

The speculation has been that it was a last minute change due to height requirements for side marker lights. Early promotional photos in 1997 for the 1998 LS400 showed the front side markers being what became the dummy lights next to the fog lights. Here are a few of the promotional photos from 1997.
