Hey Sue! I have some more pix that may help you see how I attached them to my
scooter.
The back sides of the LED strips have a strong 3M adhesive; so peel -n- stick. However, I wasn't sure I wanted them to be permanent - and there are Velcro strips across the frame that the red fabric triangle attaches to, and I didn't want to get those all sticky with adhesive. So, I measured twice, and cut once (LOL been watching too much "This Old House" on PBS! LOL) and left the adhesive backing in place where it crosses the Velcro. Additionally, since we were flying in and out of Orlando, and I knew that Angus would be in the care of the tarmac crew, I put a couple of zip-ties around the frame to help hold the LED strips in place, just in case the adhesive failed. (It didn't, BTW!)
I did "prep" the area by cleaning it with alcohol first, to help it stick better. Here come the pictures!

My "Do not remove backing" areas all marked out!
Here the strips are stuck down (no zip-ties yet). This is looking at the BOTTOM (ground) side of the scooter, so it is flipped over at this point. The strips fit almost perfectly!
Everything is installed - and the red fabric triangle is back on. Now I had to feed the little wires up right below the steering post. (Cat fur courtesy of Oreo Cookie and Dustbunny)
Not the best picture ever, but this shows where I put the little control box - in the cane/crutch holder right above the front tire, between the foot pegs. It fit in there really nicely!
Everything installed, and all "glowy"!
LMK if you have any more questions - I hope this was helpful!

The only thing I *don't* like about this setup is that there is a set screw in the cover of the battery/control box. I already had a little screwdriver in my toolkit that I keep with my battery bag for the
ECV (I have 2 batteries and 2 chargers, and a strong compulsion to always be prepared!) so it's no big deal, just frustrating if you :::ahem::: forget to turn off the lights and the battery has to be replaced...

It uses a standard 9-volt battery (alkaline) and the battery probably lasts somewhere between 16 & 24 hours total, although I have never just run it to see how long it would go. I keep a spare 9-volt in my tool kit as well (with the terminals taped off for safety) because I have found that 9-volts aren't as common as, for example,
AAA or AA batteries are. In fact, at WDW, we never did find a shop that had 9-volts for sale on property, so I was glad I brought along my spare!
