Remove low beam bulb
Remove the low beam light bulb from the headlight of your Mazda 5. Remove the low beam socket by turning it counterclockwise. Use gloves when you handle light bulbs.
Install new bulb
Install the new low beam light bulb on your Mazda 5. Don't touch the glass part of your bulb with your bare hands.
If the low beam doesn't work after you replace the light bulb, you need to check the fuses. Mazda 5 has two fuses, one for the right and one for the left headlight. In the fuse box located in the engine compartment, locate fuse 39 and fuse 40. Both these fuses are 15 A.
