Although I have visited many times and found the information and advice from other members extremely helpful, I have just joined today. I have a 1985 Mercedes Benz 300CD Limited Production Turbo-Diesel Sport Coupe, Black Exterior w/Palamino MBTex interior which I purchased new in July 1985. The car is in showroom condition, has always been garaged, never thru a carwash, a non-smoker car which took first place in it's chassis class at the 2010 Mercedes Benz of North America 2010 June Jamboree. I will provide pictures soon. In the meantime, and the reason for my joining today, is to caution those who may be considering replacing the notoriously inadequate carbon-filament instrument cluster bulbs with LED's. I followed a thread posted on from 2007 about how easy it was, what an improvement in light level the LED's provided and a link to a supplier, I purchase 2 white "5 Ultrabright SMT LED T10 Wedge LED's" from LEDLight and, as promised, they slipped easily into the existing sockets. However, the leads on the LED's wrap around both sides of the base of the lamp which brings each of them into contact with the hot and ground, or neutral, contacts on the printed circuit board within the instrument cluster, thereby creating a dead short, blowing out the 8 amp fuse which also serves numerous other circuits (circuit #1 which aslo serves right tail & parking lights, license plate light, HVAC lights, etc.). After much ado I found a fix for this and will post it soon. Fortunately the printed circuit board seems OK and the LED's actually make the gauges readable at night. I also will comment on the incredible improvement that Michellin Hydro-Edge tires have made in the handling and braking of my car. Looking forward to being a contributing member of
