Like birds4us said, you need new and or better spark plug wires.

I know Motorcraft wires are recommended around here, and you also might want to try Taylor Pro wires from http://www.summitracing.com

Actually that could be problems with the coil or problems with the plugs. What you are seeing is corona. Leakage of the high voltage D/C going through the plug wires. Corona usually appears along a resistance path, but the plug wires might be lighting up because the gap is too big on the spark plugs, or the coil pack is throwing out excess energy.
