There’s more about automotive bulbs than can be reiterated here. We haven’t brought up color temperature yet H4, HB2 and 9003 bulbs are practically interchangeable. Stick to 12V, obviously, or at least I hope it is. 62248 is an Osram part number for a 24V (semi truck?) H4 bulb.

Hopefully the Depos have bulbs installed - come to think of it i believe mine did - so this is a question for when those bulbs burn out
