Unreasonably proud of self for successfully changing the brake lamp bulb on my FIAT 500 (with some help from Peter and Paul):

Turns out the whole rear light assembly comes right off after loosening two screws in the trunk area, then four more screws pop out the bulb mount, and the running/brake light is a double-filament bulb, C$6.49 for a 2-pack at Canadian Tire. (Good thing it was a 2-pack because the first bulb’s running light filament burned out instantly on activation and I had to pull the whole assembly back out and install the second bulb, which worked fine.)
