Standard Dome Lamp Dimmer Module for 1965, 1966, 1967, 1968, 1969, 1970, 1971, 1972 and 1973 Mustangs.

Soften and modernize the interior lighting in your classic Mustang with this Standard Dome Lamp Dimmer Module. Unlike the standard shut-off, the module features delay and fade functions to keep the dome light lit for an extra two and a half seconds before it fades.

Features and Benefits:
- Microprocessor controlled
- Simple three-wire installation
- Made in the USA
- 2" x 1-1/2" x 1" plastic enclosure with mounting tabs
- Internal 7-1/2 amp resettable fuse
- Delay period approximately 2-1/2 seconds
- Fade function fully compatible with LED dome lights
- Fully potted
- 24" long, 18 gauge wires

Mount the module in a weatherproof area, then wire the connections as outlined in the installation notes and you'll have a dimming dome light in no time at all. The dimmer module uses the existing wiring to sense when the doors open and close. When the door is closed and the dome light would normally turn off, the dimmer module takes control and holds the dome light on for a few seconds (delay feature). This delay gives you time to find the ignition slot and find your seat belt.

- Controller unit
- Two T-taps
- Two zip ties
- One small crimp ring
- Two male 1/4" connectors

The standard model is rather simple to install. The dome light dimmer uses two wiretaps on the existing wires going up to the dome light which are usually easily accessible under the dash. A third wire is attached to the ground. Unlike the deluxe module, the standard module doesn't include the gradual warming up when turning on the dome light. Upgrading to the deluxe dome lamp dimmer module adds features but requires a five-wire installation compared to the three-wire installation of the standard module.

We're here with dome lamp dimmer modules, fitting all 1964 through 1973 Mustangs. We have here the standard and the deluxe version of our dome light dimmer switch module. The standard version is going to tie in to your door pin switches. When you close the doors, instead of the light going out instantly, it will slowly dim down just like a modern car would. The deluxe version does the same thing, but actually there's a few more feature and has little more wiring involved with it. This will work off of switch power as well, when the switch power is off, the dome light will stay on for 10 seconds, then it will fade off. If the switch power on because the car is running, the light will actually fade off as soon as you close the door. When the switch power shuts off completely, the dome light will automatically come on. If the door is left open for more than 10 minutes, it will shut itself off. Our dome light modules are another great way to add a modern amenity to add to your classic Mustang.
