If you are the owner of a 1977-1996 Corvette and your under hood lamp is not functioning; you may be able to repair it instead of replacing the entire unit. The C3/C4 Corvette Under Hood Lamp Mercury Switch, available from Zip Corvette, is located in the base of the bulb socket; and is only visible when the light bulb is removed. It will be apparent, upon inspection of the socket/assembly how the switch should be removed and replaced. Pay close attention to the direction in which the bullet-shaped end of this switch is installed. A mercury switch works on gravity; so, when the hood is opened, the metal liquid flows (inside the housing) and completes the circuit. If the switch is re-installed in the wrong direction – it will not make proper contact and the light will not turn on. This quick fix may just brighten up your Corvette’s engine compartment when you really need it.
