Oh yeah, I almost forgot...
The BEST deal I've seen for under-gunnel lights was a 12-pack of waterproof amber running lights (like for a truck or trailer) for $19.99.
I have them mounted in pairs under my gunnels, and also a pair inside the center console. VERY nice for night-time fishing. The amber color is perfect for night time. Bright enough to really see by, yet it doesn't kill your night vision. I've seen boats with the red lighting, and my eyes don't benefit very much from that color. Here is an old phone pic of my floor at night:
Probably not as nice as the strips, but NOT BAD for $20.
