Point lights have virtualy no power at all, and will never give you what you want. They are mainly used for candle flames, or single light bulbs. Linear Point Lights are even worse, as they obey the Inverse Square Law, and falloff very quickly. Think of shining a torch/flashlight at the moon (it’s never going to get there)
You could go to the Parameters tab, nad turn the intensity up to about 2000%, and then you may even see them.
You would be much better to use a spot light for what you wnat, and adjust the cone, colour and intensity untill you get the look that you want.
