Yes the 99 W140 have red and white for the blinkers, also I had a few nice 3 piece crystal type Red & Clear W140 tail Lamp sets for sale that are for 97-99 years I had a lot of people wanting to use them for the early W140's but There is some difference that makes them only for 97-99 maybe it is small. The three piece sets I had were the lens and reflector assemblies they need the existing bulb assembly to attach to. If they are way different you would have to modify the early ones or get the bulb\socket assembly from a wrecking yard. They also had a matching crystal center band. Did the size of the band also change? I will order more if I can get to the bottom of the conversion process.
