Minecraft Bridge with Night-Activated Lighting System

This is my bridge in Minecraft. It goes from my island palace to the mainland:

I decided that I wanted to install lights that were off in the day time and on at night, and I wanted this to be automatic in case I wasn't in my house when night fell. So I crafted a daylight sensor, with three blocks of glass, three chucks of nether quartz, and three wooden slabs, like so:

The problem with this is that the sensor turns on during the day, rather than at night. So I had to construct a simple system with redstone dust and a redstone torch to tell it to do the opposite (that is, turn off during the day and on at night):

I placed this next to the redstone dust leading to the rest of the lighting system, and that took care of the most complicated part. Next, I just had to run a trail of redstone dust down the length of my bridge with the occasional redstone repeater (as shown to the left; it takes two redstone torches, one pile of redstone dust, and three blocks of smooth stone).

It's not the most efficient use of redstone due to the admittedly odd and also quite inefficient shape of my bridge, but it looks like this:

The other thing about repeaters is that you can delay the signal. I chose to set each repeater to the maximum delay because I like watching each section of my bridge light up one by one. And now my bridge is nice and lit up during the night!
