Warnings

Tools required

Parts

• Fog light bulb × 1 — 1157 dual-filament bulb (verify original equipment specification)

Preparation

1. Park vehicle on level surface and turn off all lights
2. Allow fog lights to cool for at least 10 minutes if recently used
3. Engage parking brake

Procedure

1. 1

   Locate fog light assembly
   Note: The 1966 Corvette (C2) did not include factory fog lights as standard equipment. Verify whether the vehicle has dealer-accessory or aftermarket fog lights installed, and identify the fog light housing accordingly — typically mounted in the lower front valance or via accessory bezels. Procedure details depend on the specific aftermarket kit fitted.
2. 2

   Remove fog light bezel or trim ring
   Using a Phillips screwdriver, remove the 2 screws securing the fog light bezel or chrome trim ring to the body. Carefully pull the bezel forward and set aside in a safe location to avoid scratching the chrome finish. Verified detail (Fastener count cannot be confirmed since there are no factory fog lights on this vehicle; the count depends entirely on the aftermarket bezel/kit installed.): Exact number of screws securing the fog light bezel on the installed aftermarket/accessory fog light kit (no factory configuration exists for 1966 Corvette)
3. 3

   Access bulb socket
   With the bezel removed, locate the bulb socket at the rear of the fog light assembly. The socket is accessible from the front once the trim is removed on this model year.
4. 4

   Remove bulb socket
   Grasp the bulb socket firmly and rotate it counterclockwise approximately 1/4 turn until it releases from the fog light housing. Pull the socket straight out with the bulb still attached.
5. 5

   Remove failed bulb
   Press the bulb gently into the socket while rotating counterclockwise to release it from the bayonet-style socket, then pull the bulb straight out. Inspect the socket for corrosion or damage.
6. 6

   Install new bulb
   Using a clean cloth or while wearing gloves, insert the new 1157 bulb into the socket. Press in gently and rotate clockwise until it locks into the bayonet mount. Ensure the bulb is fully seated and secure. Verified detail (There is no factory fog light bulb specification for the 1966 Corvette because fog lights were not factory equipment. Any bulb spec must come from the installed accessory/aftermarket kit, not GM factory documentation.): Bulb specification for the installed fog light kit (no factory fog light spec exists for 1966 Corvette — verify against the specific accessory/aftermarket assembly)
7. 7

   Reinstall bulb socket
   Insert the socket with new bulb back into the fog light housing, aligning the locating tabs. Rotate clockwise 1/4 turn until it locks into position.
8. 8

   Test fog light operation
   Before reinstalling the bezel, turn on the vehicle ignition and activate the fog lights to verify the new bulb illuminates properly. Verify the bulb illuminates correctly. Only check dual-filament behavior if the installed kit actually uses a dual-filament bulb (most fog lamps use a single-filament bulb).
9. 9

   Reinstall fog light bezel
   Position the chrome bezel or trim ring back over the fog light assembly, aligning the screw holes. Install the 2 screws and tighten securely with a Phillips screwdriver, being careful not to overtighten and crack the bezel.

Reassembly

1. Ensure bezel is properly seated and all screws are tightened
2. Verify no tools or parts are left in the fog light area

Verification

• Turn on fog lights and verify new bulb illuminates at proper brightness
• Check that fog light bezel is secure and properly aligned
• Verify no moisture can enter the fog light housing through improper sealing
