We normally associate brightness with the power of a light bulb. For example, a 100-Watt incandescent bulb is generally brighter than a 60-Watt incandescent bulb. When otherwise identical light bulbs are connected in various circuit arrangements, the more current flowing through the bulb, the more power it has and the brighter it is.
As more and more bulbs are connected in series, the overall resistance of the circuit increases, which causes the overall current to decrease. This results in dimmer bulbs.
Hope this helps.
