The DEFEAT is now universal* and can be installed in other GM vehicles as well as C4 and C5 Corvettes. *July 2008 by GadgetMan.

Canadian Vette - Yes or No?

How to tell if you have a Corvette originally built for Canada? Many ask this question. Here is an easy way to find out. Check the water temperature and oil pressure gauges. If vehicle is built for Canada, they will be in metric.
This auto headlight feature is standard equipment in vehicles built for Canada.

How does it work?

The Auto Headlight DEFEAT device is a resistor gadget designed to override the automatic headlight sensor system on 1990 to 2004 Corvettes. The Auto Headlight DEFEAT creates a false signal in the circuit which tells the headlight relay that there is enough light to run with lights off. First - you need to know where to locate the sensor. In the C4 Corvettes, it is directly above the steering wheel on the top of the dash. It is a FLAT round bezel on the dash. On C5 Corvettes it is located in the center of the dash in the defroster grill. You can test this by parking outside in daylight, start vehicle, cover up the light sensor and wait to see if the headlights activate.
By following the easy installation instructions provided, the DEFEAT simply clips between the two wires going to the light sensor. Once installed, the headlights are manually controlled. You can now simply turn the headlights on and off with the dash control. No more flipping headlights! You have to remember to manually turn your headlights on at night but your car has a chime to remind you to turn them off when the ignition is turned off.
An observation - contrary to popular belief the light sensor in your dash does not turn your headlights on at night. The default setting for the headlights is "always on" unless the sensor reads enough light to turn them off. Therefore, removing the stock sensor or cutting the wires will put your headlights on permanently.

Why was this new product/design created by the GadgetMan?

As an owner of a C4 and C5 Corvette built for Canada, the auto headlight system was very frustrating. Starting your vehicle when in a garage, driving in underground parking areas or traveling under a bridge, the headlights would pop up. In the morning and evening when the sun was at a low angle and through shadows on the road, the headlights would turn on and a few seconds later turn off! Auto Headlight DEFEAT was created and the headlight problem resolved.

What does it look like?

It is a small circuit board/resistor with connectors. It matches the resistance of your light sensor when the headlights are off.

Installation is EZ?

It is a very quick and EZ install (C4 - 15 minutes; C5 - 25 minutes). Two household tools may be needed to install - a small flat screwdriver/device and pliers. Installation instructions are provided with the Defeat package. It is very straight forward. Once the DEFEAT is installed you can easily test the lights by covering the light sensor. Headlights should not flip up. You must remember to always turn your lights on and off using the manual control knob. If for any reason you want to return to stock auto headlights simply cut the wires between the colored (pink) connectors and the DEFEAT and tape the wire ends with electrical tape. Simple. Comment: If you have the original C4 DEFEAT in your vehicle, you do not need to purchase this Gadget. They both serve the same purpose, we've just made the C4 Defeat universal to match the C5 style, and for other vehicles.
