Based on PabloLie's suggestion and endorsement I installed the same LED bulbs from Amazon.
Since the comparison of LED vs regular bulbs and the modifications comes up fairly often I put together a video comparison of the two types. LED is much brighter. Like PabloLie, I did not experience hyper flash either because I already had the Euro Spec relay or it just wasn't an issue to start with. Regardless, I bought 2 packs of 2 bulbs and am happy with the results.

If you switch to the LED bulbs and experience hyper-flash you'll need to install the Euro spec "Piaggio Blinker device with hazard" from EasyParts.

The "courtesy light bulb" is weird. No idea why its so weird when easier solutions could have been done but such is the weird Piaggio Mp3.
On the Parts Piaggio webpage its described as "Torpedo shapped lamp 12V-5W" or Part number 18 (071633) if anyone ever needs a replacement storage compartment bulb.
