Mazda 6 Service Manual: Discharge headlight service warnings
Discharge headlight bulb service warnings
- To prevent electrical shock when replacing the discharge headlight bulb,
dry hands thoroughly, and carry out work in an area out of rain.
- When the light switch is on, approx. 25,000 V of high voltage passes
through the discharge headlight bulb socket. Because of the danger of
electrical shock, do not insert fingers or a circuit tester.

- When the headlights are on, high voltage flows around the socket and
bulb. When turning on the discharge headlights while working, always leave
the headlights in the vehicle-installed condition to prevent electrical
shock.
Discharge headlight control unit service warnings
- Because of the danger of electrical shock, when inspecting with a
circuit tester or similar device, do not inspect the discharge headlight
control unit as a single unit or disassemble it.

- If there are scratches or damage to the discharge headlight control
unit, or it has been impacted, there may be damage despite apparent normal
operation. Therefore, to prevent electrical shock or operation error,
replace with new parts.
Caution
Incorrect servicing of the discharge headlights could result in
electrical shock. Before servicing the discharge headlights, always refer to
