Hack in a Bluetooth Connection to Your Car Stereo for $10
For something very similar, I cut drinking straws into small sections and fitted them over the leds, on the open ends, I placed silver craft beads . The intent was to give the led a large viewing angle. I suppose if you used permanent marker on the straws the color would change.
The 24v to 36v battery modification did no apparent harm to the Razor Bistro scooter. But for the 200w Chinese scooter, when the motor is not used for a while, it takes about 45 seconds for the motor to spin up to full speed. After it has done that, everything works as usually. But if you let it sit for a few days, the same thing will happen. These scooters have a current limiting "shunt" on the controller pc board. I am going bypass the shunt to see if more current will go to the motor. When I do this, I think something may break permanently.
