NOTICE
Halogen bulbs get very hot when lit. Oil, perspiration,
or a scratch on the glass can cause the bulb to
overheat and shatter.
When replacing a halogen bulb, handle it by its
plastic case, and protect the glass from contact with
your skin or hard objects. If you touch the glass, clean
it with denatured alcohol and a clean cloth.
Models with LED fog lights
Fog lights are LED type. Have an authorized Honda
dealer inspect and replace the light assembly.
