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. With a more BLUE cast light, these bulbs will be much brighter, 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 (you can plug them either way, no problem). 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 how to get them installed in your instrument cluster. If you need that information, you can purchase Kent's instrument cluster manual separately. Some models will require special dash hooks to pull the cluster out. You can do it by hand from the backside on the W123 and the 1985 and older W126 - BUT on the later W126 and the W201 chassis, 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.
This is what they look like installed in a W201 instrument cluster. NOTE: The actual color in your car may vary slightly due to total darkness and other environmental conditions.
Note the size in relation to the original incandescent bulb. This LED is small enough that it will not touch any part of your light tunnel or reflector.
