This is for an amber turn signal bulb for a scooter. R5W with two prongs 180 degrees from each other. I bought some RY10W bulbs thinking they were the replacement but the bulb that came out was a R5W 18321. The little pegs on the RY10W bulb is off centered, so they don’t fit into the bulb holder. The bulbs have to go through the hole into the housing, so the bulb head can’t be larger than the original one. Factory bulb on the left.

Oddly enough either batteriesandbulbs plus stores, or susquehanna motorsports who are an online rally store that has everything. Or hidplanet store.
 
If you can't find the amber version, you can use amber/orange bulb dipping paint on the easier-to-find clear version of the bulb. Bulb dipping paint is translucent, heat-resistant, and long-lasting.
 
I made the RY10 bulbs work. I just filed down the off set nub. They just hold the bulb in place. The bulb is still secured with the one nub. Everything works. 👍
 
If anyone cares, I found an amber bulb with the correct prongs. I found it on ebay, a scooter shop in North Carolina. The glass is shaped differently but fits into the bulb holder without an issue.
