I've been doing some research on what bayonet and bulb types fit the Piaggio Fly 150 (4T Euro 3).
Brake/Rear Running Light
- BAW15d 1157
- BAU15s 1156
- If you're going to upgrade to LEDs you may need load resistors to reduce the fast flash rate.
The difference between BAU15s and BA15s
- I'm not sure what these are called? But you can buy or make your own:

The closest I've come to identifying what the dashboard housing is -
Below is the packet of the LEDs that best fit the dash socket. I bought them from the website above, when purchasing you'll have to specifiy the exact model as there are differing types of dash LED/globes even though they are 509T.

- 12728 S2 Philips Duplo 12V 35/35W (BA20d socket)
If you search on eBay there is a wide range of BA20d globes available. I purchased the globe below and it is a lot brighter than stock with a nice white light. The BA20d socket on this globe is slighlty smaller (maybe 1/2 a mil) so you will have to bend the connection points within the socket a little to create a snug fit.
Regarding the globe above, it melted the plastic housing, see below. The globe is very bright and makes a big difference but I'm making the readers of this thread aware of the risk.
Luckily I didn't go for a long ride otherwise the housing may have been melted through. As stated above, the stock bulb is .5mm wider in circumference which may help stop the bulb move around. I think I'll go back to a stock bulb.
If you want to remain stock, Philips Premium BA20d bulbs are rated at 30% brighter than stock. In Australia Autobarn and Repco sell Philips bulbs.
Park & Number Plate Light
- T10 or W5W
Aerpro sell a great T10 LED for the number plate - 3 x SMD
You can also change your park light globe to something like this - 5 x SMD
