Unless you have really small arms, I don't believe you can just reach up into the Cowl and do this change-over. I recommend
pulling off the cowl. Like 6 or 8 screws around the edge (dash side) and one right above the headlight in the small vent area. Here's what I'd encourage....Look up a Parts Schematic on a Kymco Parts Vendor (i.e. Stadium Yamaha). You'll easily see how things are put together. Caution...Numerous removals usually causes the plastic to strip out on the plastic holes on the cowl. I've filled mine in, re-drilled and tapped more than once. The first time to reinstall the cowl can be quite difficult. If you do change this bulb, think strongly about doing any other add-ons like dash mounted 12 VDC receptacle, any extra switches, lights, air horn, etc. Removing a panel of some type is required to do most maintenance procedures.
