Before the bulb can be replaced, the plastic covering over the headlight housing has to be removed, see the article "Replacing bulbs."
Important
Never touch the glass of bulbs with your fingers. Grease and oils from your fingers vaporize in the heat and will leave a deposit on the reflector, which will damage it.
Remove the low beam round rubber cover from the headlight housing.
Remove the connector from the bulb.
Remove the bulb by pressing it slightly upward and then pulling it out.
Insert the bulb in the socket. The bulb's guiding pin should point straight up.
Press the connector into place.
Put the rubber cover back into place.
