If you replace the turn signal light bulb on your Mazda and the lights still don't work, it is possible that the fuse for the turn signals is blown.

Check fuse 24 in the fuse box found in the engine compartment. The fuse is designated as HAZARD and will be a 10 A fuse.

Follow these instructions to change the back turn signal light on Mazda5. These instructions apply to both passenger and driver side.

Do not touch light bulbs with bare hands as that can shorten the life of the light bulb.
Installing LED bulbs:
- If you are upgrading to LED light bulbs, and the bulb doesn't turn on when you install it simply remove the LED bulb and rotate it 180 degrees and reinstall it.
- Certain vehicles may trigger a fault message stating faulty or burned light bulb when the original bulb has been upgraded to LED. If that is the case, use halogen bulb or get an Error Free LED bulb.
