I have the Custom Dynamics "MagicFLEX" strips in blue on my 2011 SECU and the blue really pops.
My son liked it so much he wanted the same thing for his 2010 Fatbob, only in Red. So we ordered some and the Red Pops pretty good too.
I used their kit description as a guide to ordering, and then just ordered the individual pieces I figured I'd need and actually use.
It's been awhile since I put them on myself, but I think I put a 12" strip under the gas tank on either side... a 3" or 6" strip under the engine heat guards at the saddle... and a 6" or 9" strip inside the Saddlebag fillers... and one 12" strip under the tourpak.
These strips are flexible as far as being able to conform to a flat/curved surface... but you can not create an "S" with these particular strips. Custom Dynamics does however make a set that are flexible in any direction, but I'm not sure if they use the same 3M method of adhesion.
For my son's Fatbob, we did the same with the Tank... found a little niche where we could direct some light from under the saddle, and then place some on the inside of the rear fender.
Now, compared side by side to the blue, the Red doesn't really stand out... but by themselves without any other distractions, they definitely stand out. Especially at night... when you'd most likely be using them anyways
