Why would both my headlights go out at the same time?

When both headlights stop working at the same time, the bulbs usually aren’t at fault. The main exception is when one headlight burns out first, goes unnoticed for some time, and then the other bulb also fails. If this is the case, then replacing the bulbs should fix your problem.

Is it common for both headlights to fail at the same time?

when she’s naked! There are many things that can cause your “both headlights” problem, but I have found the most common to be that both headlights are burned out. Sounds simple doesn’t it?

Why are the headlights on my Mazda CX-7 not working?

The 2010 Mazda Cx-7 headlights simply fail to achieve this. This is clearly a case of form over function, but in this case it had led to a serious safety concern. The headlights (low beam) on my car simply stopped working all of a sudden. Checked the fuses and all are fine.

Why are both low beams on my Mazda 3 not working?

I have a 08 Mazda 3. Both of my low beam headlights quit working at the same time. I checked the fuses both under the dash and hood and they are all good. Checked volts at the headlight connection and there is none. I have seen a lot of posts regarding this but none that have a fix.

Where are the headlight relays on a Mazda3?

Both headlight relays are inside the PJB, and not accessible unless you disassemble the PJB. I don’t even know if they can be replaced… they are likely soldered to the circuit board. If the highbeams also do not work then, you should check the 40A fuse in the fuse box under the hood (F4).
