9. LIGHTING LIGHTING SYSTEM LH LIGHTING SYSTEM PRECAUTIONS 1 PRECAUTIONS WHEN REPLACING HEADLIGHT BULBS a Because halogen lights become extremely hot when in use the life of the bulb may be reduced in the event that the surface of the bulb comes in contact with oil or another similar substance When replacing the bulb hold the flange part and do not touch the glass with your bare hands b Halogen bulbs have pressurized gas inside and can be damaged or shattered if dropped bumped or scratched c Because dirt and moisture can enter the lens of a bulb that is removed and left out for a long period of time have a new bulb on hand before performing bulb replacement d When replacing a bulb always use a bulb of the same specification e When replacing one sided bulbs keep in mind that there is a difference in the brightness and luminescent color of left and right bulbs f If bulbs are not properly installed in their sockets water and mist may get inside the lens Therefore after replacing bulbs make sure that they have been securely installed g Flying glass shards can cause injury Therefore do not break bulbs when disposing of them after use 2 PRECAUTIONS WHEN ADJUSTING HEADLIGHT BEAMS a Do not cover a headlight for more than 3 minutes when the headlights are ON b Because the outer lens of the headlight is made of resin there is a possibility that the outer lens may melt if it is covered for too long while
