What is the ford ranger t6 headlight bulb size?

The Ford Ranger T6 uses a H4 light bulb for the headlights. To replace them, reach behind the back of the headlight assembly and grasp the cap and rotate it counterclockwise to remove it. Next grab the back of the bulb and twisted about 1/4 of a turn counterclockwise to release it and then pull it straight out of the socket. Now push the tab on the electrical connector and unplug it from the bulb. When putting the new bulb in be careful not to touch the glass because the oils from Your fingers could cause the bulb to burnout within seconds of turning it on. Insert the new bulb into the opening and align the three tabs and rotate it clockwise until it locks. Don't forget to plug the electrical connector back in
