Lights! for under $2

 So I was walking around Walgreen's thinking about my build and waiting for a prescription when I walked past the back-to-school section. There they had mini light bulb flashlights that were in 3 colors; red, white, and blue. They were only $1.29 each ans I thought "I have my lights!" ( for the HP, and PSI's that is ). I tested them out and they are very bright.

White- HP
Red and blue- PSI

Unfortunately they don't flash or alternate but they will be easy to mount and leave on. Just lift the dome before hand and click them on.
