A vast improvement in lighting output
 

The glowworms formerly in my housings were dangerously inadequate. After installing their low beams and being impressed - the color-changing version on this round. They have a daylight white mode, halogen(ish) color, and an off-road yellow mode for snow/rain use. They are quite a substantial increase in terms of safety, and super easy to install. Initial impressions are strong.

Below is the showing video from my youtube.
