Nope, my manual gives not hint to bulb replacements.
On my Kymco, under the rear fender, is a black rubber/plastic cover held in place on one end by a couple of those push/pin panel clip/rivets. Laying on back, with flashlight, I removed that panel and found the taillight bulbs. Twist to remove.
You might have to remove license plate rear fender thing to see under there.
Hope your scoot is similarly built.
