Fitment Note: Do not use on fuel injected bikes.
They do light up and they are really simple to install. However, they light up orange not blue, and there were no instructions. They seem to work great, and I don't believe I'm losing any performance in running these
Nice plug caps
It is better to have performance than the cheap look. this is a brewakable item
Llike these. Very neat at night.
Junk..does not produce blue light, and only good for single cylinder or twin cylinder engines. Spark too rapid for four cylinders or more makes steady light.
