LED dash light bulbs

I want to convert my old standard bulbs to the new LED ones. I know the bulbs don't cost much, maybe $1 each or something, but I don't want to buy crummy ones that start flickering and failing 2 months after I put them in.

Has anyone converted and how are the results? Are there any quality brands out there that you know of, or do you know which brands to avoid?

Also how many lights on the dash? There's 1 or 2 for the speedometer cluster,
one for the a/c controls, one for the shifter, and what other ones?

Thanks,

Short of any replies.....

Short of any replies, I guess I'll just have to call a MB parts dealer to see what bulbs they have. I just don't want to end up with any junk from China where I'm driving down the road and the lights start to flicker then suddenly quit. I don't want to do the job twice.

LEDs pretty much all come from China. The $1-$2 ones are garbage. There's some that Kent sells, they work well. I've had good luck with name brand bulbs - you can buy them from Walmart, autozone, or any auto parts store. You will pay a premium, but I've had no issues with any of them at all. All my dash lights are LEDs, including the back lighting on the center console and HVAC knobs.

I'm running these : https://www.superbrightleds.com/moreinfo/miniature-wedge-base/194-led-bulb-3-smd-led-miniature-wedge-retrofit-car/3551/

And they are good at night. My dash lights (spider lights) aren't working now though, haven't figured it why.

For the link you gave, those look like speedometer cluster bulbs, and not for the shifter area and climate control, etc. Is that what those are?

And what are spider lights?

The “spider” refers to the fiber optic light distributor behind the dash that lights up the rocker switches above the heater controls. One bulb lights up all these switches.

I played with LED's on my w123 cluster. While not the same, something to consider are bulb dimensions. Your LED bulbs that you're looking at might have the same bulb base as their incandescent equivalent, but the bulb height may be different. As i remember, in some instances the bulb was too tall such that i couldn't even screw in the base.

I used these for the main bulb pair in the cluster. The white frosted cap will come off allowing it to fit perfectly in the cluster.

How do you change the climate control bulbs?

Years ago I'm smartly used a straw to go over the bulb to then pull it out, preventing me from having to take apart the whole assembly. But this time I don't have and can't find the same diameter straw.

If I wanted to take that plastic assembly apart that holds the bulbs how can I do that without breaking any of the plastic clips that appear to keep the two halves together?

There is actually a tool made for this purpose, the name is “lamp extractor”. It was developed for the telephone industry for the little incandescent bulbs used on the operator switchboards and the older key system business phones. They continue to be used on industrial control panels for removing incandescent bulbs in operator devices. Just looked on eBay and there were several offered in the $10-20 range.

A piece of rubber tubing also works very well for this.

Someone else said 1/4 rubber tubing

Someone on a thread long ago said 1/4" rubber tubing would do the trick.
