Kent has found and tested this newest LED light bulb that you can install on the backside of your instrument cluster to increase your instrument lighting on your older Mercedes. These particular bulbs will be much brighter with a more yellow cast warm white light, and they don't get hot! All the chassis models mentioned above use two bulbs to illuminate the dash at night. These are direct replacements for the original incandescent bulbs, and this new generation is NOT polarity sensitive. These bulbs are also fully dimmable if you have a working dimmer switch. Watch the videos below as Kent demonstrates his testing procedures, explains polarity, and shows the advantages of this new-generation LED bulb.
Product Details
PLEASE NOTE: These bulbs DO NOT COME WITH INSTRUCTIONS on installing them in your instrument cluster. You can purchase Kent's instrument cluster manual separately if you need that information. Some models will require special dash hooks to pull the cluster out. You can do it by hand from the back side on the W123 and the 1985 and older W126 - BUT on the later W126 you may not be able to get the cluster out of the dash without these special tools. See related products below to order instructions and dash pull tools separately.
The picture below shows the difference in size between the original bulb and our new LED. It is slightly longer but still fits with room to spare and runs quite a bit cooler than the original factory bulbs.
Here is what they look like installed in a W126 instrument cluster on the bench (not fully dark).
