These instructions apply to the Mazda CX-5 Mk1 (KE) 2012-2017.

Whether you can change a headlight bulb on the Mazda CX-5 Mk1 (KE, 2012–2017) yourself depends on which headlamp your car has. Halogen cars use ordinary replaceable bulbs you can fit from the engine bay; Bi-Xenon (HID) cars use a high-voltage D4S bulb that is a dealer job. There is no full-LED headlamp on this generation.
Which Bulbs Does the CX-5 (KE) Use?
| Light | Halogen cars | Bi-Xenon cars |
|---|---|---|
| Low beam | H11 (55 W) | D4S xenon (35 W) – dealer only |
| High beam | HB3 (60 W), or H15 where combined with daytime running light | shared D4S projector |
| Front fog | H11 (55 W) | H11 (55 W) |
| Front turn signal | PY21W (21 W) | PY21W (21 W) |
| Parking / position | W5W (5 W) | P13W daytime running light (13 W) |
How to Replace a Halogen Headlight Bulb
- Switch the lights and ignition off and open the hood.
- Work from behind the headlamp. On the right-hand side you may need to lift the washer-fluid reservoir neck out of its guide for room.
- Unclip the electrical connector from the back of the bulb (press the tab and pull it straight off).
- Twist the bulb holder anticlockwise to release it, then withdraw the bulb straight out of the reflector.
- Fit the new bulb without touching the glass with bare fingers — skin oil shortens its life. If you do touch it, wipe it with alcohol.
- Refit the holder, reconnect the plug and test the light before closing the hood.
Frequently Asked Questions
What low-beam bulb does the CX-5 take?
Halogen cars use an H11 55 W low-beam bulb. Bi-Xenon cars use a sealed D4S xenon that should be replaced by a workshop.
Can I change the xenon (HID) bulb myself?
It is not recommended. The D4S runs on a high-voltage igniter that can give a dangerous shock — leave xenon bulbs to a dealer.
Does the CX-5 KE have LED headlights?
No full-LED headlamp was offered. Only the side-marker turn signals and the high-mount brake light are LED, and those are sealed units.
If a bulb-out or lighting warning is logged, you can look up the code on autodtcs.com.
