new third brake light ?

The 3rd brake light went out in my DX sedan, and I figured while I had to replace it I might as well put a whole new brake light in......I've seen pics on here of someone who replaced a sedan 3rd brake light with a longer, narrower one, but don't know where they got the light from, what the light was originally for, or how they fastened it down? Any help on this would be much appreciated.

JC Whitney has a bunch of different (aftermarket) 3rd brake lights. They even have some cool LED style lights that are pretty small... Pretty cheap too - only about $10-20...

Hope this helps :iceslolan
