free of corrosion or dirt.
6. Install the locking ring onto the bulb, then line up the replacement headlight bulb with the harness
plug. Firmly push the bulb onto the plug until the spring clip latches over the bulb's projection.
Do not touch the glass bulb with your fingers. Oil from your fingers can severely shorten the life of the bulb.
If necessary, wipe off any dirt or oil from the bulb with rubbing alcohol before completing installation.
7. Position the headlight bulb and secure it with the locking ring.
8. To ensure that the replacement bulb functions properly, activate the applicable switch to illuminate
the bulb which was just replaced. (If this is a combination low and high beam bulb, be sure to check
both intensities.) If the replacement light bulb does not illuminate, either it too is faulty or there is a
problem in the bulb circuit or switch. Correct if necessary.
