PRECAUTION
1. PRECAUTION FOR HEADLIGHT BULB REPLACEMENT
(a) When any defects such as deformation, cracks, dents, chipping, etc. are identified on the headlight, replace it with a new one.
(b) Even if the operation seems to be normal, the fail-safe function may be defective.
(c) Since halogen bulbs (for headlight or front fog light) have pressurized gas inside and can easily be broken if scratched or dropped, special care should be taken. When handling the bulb, hold the plastic or metal part and do not touch the glass part with bare hands.
