C3 Fiber Optic Boots and Ferrules
Zip now offers 1968-1971 Corvette Fiber Optic Boots and Ferrules that will repair your Corvette’s factory headlight or rear tail light harness.
Often, the end of the fiber optics ferrules are broken and the ferrule is gone. The quick fix for many is to glue, tape or adhere the fiber optic harness into the lens, however this impairs the fiberoptics and won’t allow the light to travel through the optic, in turn not allowing the display on your console to work correctly.
Coupled with our Corvette Fiber Optics Repair Kit, you can completely repair your Corvette’s original harness and install factory ferrule ends and boots for a correct installation.

Corvette Dome Light Circuit Boards
Corvettes from 1978 to 1989 have a courtesy or dome light timer which leaves the interior lights on for a short period of time after the last door is closed. On a late C3, the courtesy light timer is located below the right A-pillar and behind the dashboard trim. On an early C4 Corvette, the dome light timer is behind the right side of the instrument panel.
Zip Corvette sells replacement circuit boards for both the 1978-1982 C3 and 1984-1989 C4 timers. With both C3 and C4 Corvettes, once you get the timer module removed and disconnected, you simply open the timer, remove the existing burned-out circuit board and replace it with Zip’s new circuit board.
If you are buying a board, there is also a choice of two light shut-off strategies. Zip Corvette’s standard dome light timer board has the stock delay on light shut-off after the last door is closed. Zip, also, has a no-delay circuit board which eliminates the delay, ie: when the last door closes, the courtesy lights go out immediately.
All of Zip’s Corvette Dome Light Timer Circuit Boards are made in USA. They are burned-in and tested before shipping. Each timer uses the existing stock connections so no wiring work is required for installation.
C4 Corvette Circuit Board Update – 2/7/11
1984-1989 C4 Corvettes could have three different interior lamp delay modules installed in them. The modules can be quickly identified by the part number on the outside of the housing.
The connectors are the same for all 1984-1989 C4 Corvette modules. The difference is in the module function! 14066560 & 14080625: when the key is turned off the interior lamps do not come on. Lamps only come on when the door or hatch is opened. 10098435: when the key is turned off the interior lamps do come on.
If you are replacing your 1968-1982 C3 Corvette’s dash or are just trying to remove your Corvette’s Headlight Switch assembly, here is a helpful tip that will make the removal and installation much easier.
Every week we have at least one customer call and ask us this question, “How do I remove the knob and rod from my headlight switch?” It is a very common problem that everyone encounters the first time they try to do this.

NOS (New Old Stock) Corvette T3 Headlight Bulbs are not all they’re cracked up to be. Besides the fact that a single NOS headlight bulb from a swap meet costs nearly just as much as a new Reproduction T3 Headlight Bulb Set from Zip Corvette, they typically don’t work properly. The reason is simple; as the bulbs set, they tend to crack allowing air to enter the area that should be under a sealed vacuum. With air entering the bulb, the filament will either burn out immediately or last a very short time once power is applied.
Since all of our
Corvette T3 Headlight Bulbs are 25% brighter than any NOS or used bulb, they are sold in complete car sets. If you installed just one new bulb you would be able to clearly see the difference between the old and new. All Corvette T3 Headlight Bulbs from Zip are produced from original GM blueprints and are built by an OEM manufacturer. They also meet all current Federal lighting standards and are guaranteed to produce more light than any NOS or used Corvette headlight bulb on the market.

Today’s Corvette technical question comes from Jay who owns a 1977 Corvette:
How do you adjust the “back” of the headlights on a 1977? I know where the front adjustment is, but mine rubs on the back when they are opened. I have several manuals and have looked everywhere on the car I can think of. Can you help?
Answer: There is no adjustment for the back of your Corvette’s headlights. If your headlights are rubbing the surrounding fiberglass, we would first suggest unbolting the headlights and changing their position within the opening. The bolts mounting the frame to the front and rear headlight bars on the fiberglass have some adjustment in them, loosen the bolts and reposition the headlight housing in the opening. An additional issue may be worn out or misaligned side bushings where the headlight housing mounts into the headlight frame. These bushings are plastic and once cracked and brittle, will allow the housing to move around in the frame. Verify whether the bushings are broken and if not, loosen the bolts and reposition the headlight housing within the frame. There is adjustment in those bolts as well that will allow you to control the headlight housing position.

Corvette Headlight Knob
Though it may not seem like much, this C4 Corvette Headlight Knob is a great replacement for 1984-1989 C4 Corvettes. Other replacement headlight knobs will require the headlight switch to be removed, which means the dash has to come out resulting in hours of hard work just to replace the knob. This can be very time consuming and frustrating for something so small as a cracked or faded headlight knob so Zip Corvette now offers this newly designed headlight knob for C4 Corvettes. Now available from Zip Corvette products, this headlight knob will fit onto the original shaft allowing for a quick and easy install.
