One filament in the headlamp bulb.

Am I missing some detail about the Yaris headlamp bulb? On-line I was looking at different Yaris headlamp bulbs. The headlamp bulb is listed as 65/55W. But all I could see in the clear headlamp bulbs is just one filiment. It looks like the Yaris uses resistors and/or relays to create high beam, low beam and daytime running lights. If I am right, when the DRL burns out the filiament in the headlight bulb, you need to replace the headlamp bulb before dark (or have fog lamps as a backup plan) to avoid driving a one eyed monster.
