| Before installing bulb, check bulb carefully for
damage. Then, with a towel lightly dampened with window glass cleaner or
rubbing alcohol; wipe all fingerprints, dust and impurities from bulb's
glass surface. Let dry thoroughly before installing. DO NOT TOUCH GLASS
with fingers after cleaning. Handle glass with clean dry towel or cotton
glove. Also, make sure bulb is warmed up to room temperature before installing. When used, bulb may shatter or explode if very cold, or if it contains fingerprint oils or moisture. This is especially concern for Halogen and high wattage/temperature bulbs. |
| Floating Debris: Turn bulb sideways and lightly tap with fingernail. Loose glass floating inside probably was caused by rough handling. Look to see the shape of the glass pieces. If they are flat flakes or thin shards they probably came from the reflector edge and bulb should be okay. BUT, if glass pieces are "chunky" they probably originated around electrical contacts or structural supports and if airtight seals are damaged; oxygen can enter shortening bulbs life. Use this test to also check for "floating" broken internal components such as supports, insulators, wires, filaments, and foreign debris which may not have been cleaned out before bulb was assembled. Depending on what's floating and as long as air doesn't enter, bulb may still live out a normal life. |
| Oils from fingerprints and other contaminations on quartz bulbs causes devitrification chemical reaction when bulb is heated. Quartz glass crystallizes becoming brittle causing premature glass failure (bulb could explode.) |
| At the factory, each bulb is turned on for testing anywhere from seconds to minutes (depending on the bulb type) so some minimal signs of usage are present with every bulb. Some bulb designs have filtered glass (like UV coating) which may appear slightly tinted (not blackish). I have personally tested each bulb that I send to you and guarantee it working when I shipped it to you. If for any reason the bulb fails in the first 90 days return it for a full REPLACEMENT. |
| Normally reflectors
are silver plated. Use a good silver polish and a CLEAN (washed in a wash
machine) soft cotton cloth. Do NOT USE Paper towels, they have dirt embedded in them! |
Focus that Driving/Fog/Head Light.
| I have a CATS-EYE Fog lamp for sale. I had to remove a screw from the rear to get the reflector out. Then I found a spring laying inside. Then I notice that the bulb receptacle slid inside the reflector assembly. Now the light in my head comes on. This is how you focus the bulb to the reflector. Turning the screw moves the bulb in and out of the reflector and gives the perfect SPOT. |
