-Direct replacement Nissan Z32 and Lamborghini Diablo headlight lenses.
-The lenses are manufactured via polycarbonate injection molding. This process yields high quality composite parts in a repeatable manner.
- New Polar Engineering lenses retain a ridge on a bottom flange surface and seamlessly snaps into a matching groove on a headlight housing.
-The lenses accept factory weather-stripping and mounting brackets.
-POLAR logo is molded into the upper section of each lens. It is not visible once lens is installed using factory weather strip and retaining brackets.
NOTE: four metal spring clips are no longer used during installation.
1. Please wear gloves when you are installing your new lenses. It is a lot easier to keep lenses clean than having to wipe down fingerprints
from the interior of your headlight.
2. It is best to test fit the lenses with thin plastic film still on and only remove the film from the back side right before installation.
3. I strongly suggest spending most of the time during installation removing old silicone sealant from headlight housing. It is best to work
in 2-3” sections. Carefully heat the silicone with a heat gun and scrape it off with a small, flathead screwdriver. The more carefully you
perform this step, the better final result you will have.
4. Please use new silicone strips or tubes to seal your new lenses onto the headlight housing. Heat up the sealant with a heat gun evenly
all around until sealant becomes soft. While sealant is soft, press your new lenses into the headlight housing mating the groove on the
housing with a ridge on the lens. New lens installs exactly like the factory counterpart, minus the 4 metal spring clips. They are not
needed for installation.
5. DO NOT use excessive force when installing the lenses and do not apply pressure in the center section of the lenses. It is best to firmly
press the lenses with your hands around the perimeter. If you need to apply clamps while sealant cures, only install soft jaw clamps
on the flange where plastic is thickest.
6. DO not put the headlight with lenses installed into an oven. If you properly execute all steps above, that will not be necessary.
Care and maintenance
It is important to understand the manufacturing process of composite lenses to take better care of them in the long run. Lenses are made by
injecting polycarbonate into a mold and then cooling it in a controlled fashion. Polycarbonate is a plastic of choice my most OEM manufacturers
for headlight lenses because it has great impact resistance and is extremely transparent. While it has better UV resistance than most plastics, it
will still react with sunlight if left untreated. To address that issue, all polycarbonate lenses are coated post production and that coating is cured
with UV light. Think of is as sunscreen being applied before you go outside.
For that reason, it is very important to prevent any action that may put excessive wear or remove the UV resistant coating. Please avoid using
abrasives on your headlight lenses (polishing pastes), orbital polishers or any other hard materials/cleaning pastes. It is best to rinse the lens
when washing and wipe them down with a soft microfiber cloth without excessive rubbing. That will preserve the top coating and will keep your
lenses looking new. Some detailers suggest ceramic coating your lenses to further extend lens coating life.
It is assumed that the installer has adequate experience with headlight lens replacement. If any questions arise, or more clarification is needed DO NOT PROCEEDWITH INSTALLATION. Please contact Polar Engineering for clarification.
