The lights that I use to illuminate the clear corners are the PIAA Xtreme Whites (194 Wedge Bulb) which you can also get from Custommaxima.com. I got the PIAA Xtremes because of their recommendations from fellow Maxima.org members and the fact that I use PIAA Xtreme Whites throughout the rest of the car. I wanted the entire car to use the same brand & style bulbs. The PIAA Xtreme Whites are brighter than stock bulbs yet give a slight tint of blue.
The clear corners are very easy to install. First remove the original front amber corner light by taking a butter knife wrapped in a paper towel and pry gently behind the thinner side of the oval light toward the rear of the car.
Once the stock front amber corner light is removed take the bulb housing off of the back of the corner light by turning it 90 degrees clockwise. Then remove the stock bulb and replace it with you new bulb of choice.
Now, what I would suggest doing, is place a thin bead of clear silicone sealant around the edge of where the plastic and the reflector of the corner light meet so that you can reduce the chance of condensation build up from rain. Next, put the bulb housing back in the corner light by turning it 90 degrees counter-clockwise. Then, just pop the corner light back into place.
As for the rear clear corner light you more or less follow the same steps as above. The only difference is that I would suggest prying the larger side of the oval closer to the front of the car because it is easier to remove that way.
For a inexpensive price tag the clear corner lights give the car that euro racing look and a nice contrast from the black paint on the car. I feel the clear corners look much better then those ugly stock amber and red corner lights that come stock on the car.
