An electronic control suspension system for vehicles is provided. Subsequently, the light is received at an intensity-color modulator that includes at least one Fabry-Perot filter having a tunable optical property. The amount of reducing the adaptive codebook gain may be varied. The compression section of the line selectively biases against a portion of the line extending out of the working passageway so as to selectively lock the line to the body when the line is tensioned against the body. Electroluminescent compositions comprising the same are also provided.
