Meaning
To be unintelligent or slow to understand.
Cultural Background
In Spain, the phrase is often used with a touch of 'retranca' (sarcasm). It's very common in rural areas to describe the 'tonto del pueblo' (village idiot) in a way that is both cruel and descriptive. While understood, Mexicans might more frequently use 'no le sube el agua al tinaco' (the water doesn't go up to the tank) to express the same idea with a more local flavor. In Argentina, you might hear 'no le llega el agua al tanque' or simply 'es un nabo' (he's a turnip). 'Pocas luces' is considered a bit more formal or 'old-fashioned' but still widely used. Colombians might use 'ser lento' or 'no tener ni cinco de frente' (not having five [fingers] of forehead/intelligence). 'Pocas luces' is perfectly understood in Bogotá.
Careful with 'Ser' vs 'Estar'
Never use 'estar' with this phrase. It describes who someone IS, not how they feel.
Use 'un poco' to soften
Adding 'un poco' makes the insult sound more like a casual observation and less like a direct attack.
