This is the newest LED light bulb Kent has found and tested 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 VERY RED cast light and they don't get hot! All the chassis models mentioned above use 2 bulbs to illuminate the dash at night. These are direct replacements for the original incandescent bulbs and this new generation is NOT polarity sensitive. If you have a working dimmer switch these bulbs are also fully dimmable. Watch the videos below as Kent demonstrates his testing procedures, explains polarity, and shows the COLORS and advantages of this new generation LED bulb.
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 models, 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.
CAN’T DECIDE WHICH COLOR? Buy 3 different colors and one of the three will be free. See related products below.
