..it's very possibe that something has fried...good chance it is the cdi...
..your scoot's wiring in general, is rated for particular amp draws...
..to install any auxillary lighting, it's always best to run another wire from your battery's positive terminal, thru a fuse that is rated at whatever the total amp draw of your lights will be, then go thru a toggle switch of any sort, then out to the light's positive leads...from the lights negative leads, run another wire to your battery's negative terminal..
..i have all kinds of LED lighting on my scoot..LEDs draw very small amount of current as opposed to neon lighting, which require a "transformer" to power the lights...
..I wish you luck...
peace
