Word of caution about replacing warning lights with LEDs on W124s... The Battery Charge, SRS, Check Engine, and Brake lights do not like the LEDs and you must use a conventional bulb, especially on the battery charge. LED on the battery charge will cause the charging circuit to not charge and the warning lights will not go out after engine starts. Also, the light bulb and holder on some of the lights are intigral units and you will have to remove the old bulb and solder in the new LED. I got my LEDs from SuperBrightLEDs.com, #74x is the item number. I used red, amber, a blue for high beam indicator, and green for turn signals. You do have to get the polarity right or they will not light up. Don't use the high power ones (#74xHP), they are too bright. Actually, it was more trouble than it was worth. I would not recommend it. If everything is working, leave it alone.

If, for some reason, you do have to remove the instrument cluster, pull hard, but gently. After removing the instrument cluster, make sure you have all four rubber pads still attached and use a small amount of synthetic grease on the clips that hold it in place. It will make it a lot easier to re-install and remove again in the future. I used Castrol Fully Synthetic grease because it is a light color and doesn't stain if you get a stray glob of it somewhere.
