touches something flammable. Wait for the

Do not touch the glass part of the headlight
bulb to keep it free from oil, otherwise the
transparency of the glass, the luminosity of
the bulb, and the bulb life will be adversely
affected. Thoroughly clean off any dirt and
fingerprints on the headlight bulb using a
cloth moistened with alcohol or thinner.
