Aiming is not necessary after replacing the bulb. When aiming adjustment is necessary, contact a NISSAN dealer.
Do not leave the headlight assembly open without a bulb installed for a long period of time. Dust, moisture, smoke, etc. entering the headlight body may affect bulb performance. Remove the bulb from the headlight assembly just before a replacement bulb is installed.
Only touch the base when handling the bulb. Never touch the glass envelope.
Touching the glass could significantly affect bulb life and/or headlight performance.
High pressure halogen gas is sealed inside the halogen bulb. The bulb may break if the glass envelope is scratched or the bulb is dropped.
