i just made a headlight for an OGRR-er from clear resin. It worked great in his engine. However, in order to get a brighter beam without changing the bulb you change the focal length of the lens. To do that you need a much thicker lens that could not fit in most engines.
So, I was thinking of printing a miniature Fresnel lens. Thinner cross-section but brighter as much thicker lens with a larger focal point.
But way too many projects ahead of this one.

Why not just use a 5mm LED instead of a 3mm LED?
