You are seeing corona effect.So I have an Accel Ignition Coil and Motorcraft wires.
It is a really clear, dark night here, had the car running and I can see the light in the wires.
Ummm guys
See I have seen this effect on the plug to the engine, but I could clearly see the coil wire. It was kind of neat, but was worrisome. Appreciate the responseYou are seeing corona effect.
Corona effect, also known as Corona discharge, is a relatively rare phenomenon that can cause a glow on spark plug wires.
This event (visible in the dark) appears as a bluish-white glow around the spark plug wires, and may branch between wires or to an engine ground surface. Corona discharge does not necessarily indicate a problem with the spark plug wires but is more likely a maintenance or installation issue. This discharge is virtually silent as compared to the 'snapping' noise heard when a wire is actually leaking high voltage.
The cause of Corona discharge is the ionization (making conductive) of the surrounding air. Ionization releases electrons from the oxygen molecules and the resultant energy release creates photons (light) to be produced. This ionization is caused by the presence of large voltage differentials pulsing in the wire.
Certain contaminants on the jacket of a spark plug wire can enhance the liklihood of this phenomenon to appear, such as accumulation of oil or grease, dirt or paint overspray. Spark plug wire routing will also have an effect. If spark plug wires are allowed to touch an engine ground surface or if they are bundled together tightly, the chance of Corona discharge is greater. Alternate fuel vehicles, such as propane or natural gas powered, can see increased liklihood of Corona discharge as well. Residual vapors from these fuels cause easier ionization of the surrounding air.
To minimize the chance of Corona discharge, spark plug wires should be kept relatively clean and free of noticeable amounts of contaminants. Spark plug wires should also never rub against metal engine parts such as valve covers. Proper loom clips should be used to separate plug wires. Avoid bundling wires together with cable ties

Pfffttt...That is a straight copy and paste.Not sure if you wrote that or C&P'd it. But still interesting.
He's precious, whats his name? Got to love a smiling dog. My golden smiled all the time, that's what they do !
