Very good compact light source - Viridian CTL Compact Tactical Light

Seems to be a pretty solid rail light. Fits my Tanfoglio Witness P (large frame) well though there's a slight gap near the trigger guard but that's the pistol's design, not the light's. Puts out a lot of light over a large area and the ease of both turning on and switching between spot and strobe is super simple. This is definitely a contender for my other pistols, too.
