What type of bulb am I looking for to work with my DEPO Euro headlights?
All I have found so far with searches is the bulb is around 5W...but I couldn't find any particular recommendations, or even the type of bulb needed. It comes with a connector so all I need is the bulb I assume...

Also, how exactly do the city lights work? When the car starts or what? I never knew my headlights had city lights until today...so I thought it would be cool to have them going.
If not, is there a way to have them automatically turn on as soon as the car starts?

Much appreciated!
