No, it is SD but cluster is the same. You need 2 wedges, remember WHITE LED's are even brighter, they are slightly on the blue side too. I just went space ship all the way with bleu..

Is there an LED in a package that screws right into the back of the cluster?

Post #12, first picture. It does not screw, its a wedge made of 5 LED's.
Expensive but very very bright, regular single LED wouldn't do the work.

Well, not really screw in, but 1/4 turn.

But I see the item to which you refer.

5 Ultra Bright SMT L.E.D. T10 Wedge LED Light
Product Code: 45689

It will replace the bulb in the 1/4 turn socket?

popped mine in and they don't illuminate, any tips?
its an 81 300sd, i even bought the small bulbs for other lights with no luck either, what am i doing wrong?

Hi.
I know that this thread is old but I hope any of you guys would get a notification of my post.

I have an 87 300SDL and although I have read quite a few posts about upgrading the instrument cluster lighting to LEDs, I still need help.

I bought the LEDs, exactly like those shown on freeride's pictures. My problem is that I install them and they just don't turn on.
I turn then around because I read that there is 50% change to place the + on the right side and nothing.
I insert the old incandescent bulb and it works.
What am I missing?
I know it's got to be something stupid.

I also saw some cool self powered dials on youtube video W126 SEC LED Dial Faces - YouTube .

I wrote the guy who uploaded it and asked where he got them but he has not replied.

And the last one, does anyone know about any after market clusters for the w126 that are more updated than the OEM culster?

Thanks.

Check the small metal tabs on the bulb holder. They have a tendency to snag and bend to where they are no longer contacting the cluster housing.

With regards to the "updated" cluster, I'm not sure what you are wanting. There are a couple of places that refurbish the clusters but usually this involves repair to original.

There are some after market LED cluster faces, but I have never found any alternative cluster assemblies.

Bumping this old thread up...

I modified the LED lights I had installed for my SDL's cluster backlight tonight. Doing so almost doubled the brightness... it looks great!

The LEDs I have are the flat, almost T shaped kind with a board soldered to a board. The modification is to separate the 2 boards and solder wires between so that the "face" of the led module is adjustable. Angle it up, and move the whole thing slightly above. The result is much more light entering the light pipe.

I had previously lined the bulb areas with aluminum foil, a trick I learned when working on the cluster from my Audi 5000. It helps a bit.

My light pipes were still in good shape. This is working well enough I think I'll put off ordering the MoMan cluster faces for now
