Received the trailer hitch cover yesterday afternoon. Thanks for the quick service and for the product. I've already had other Marines asking where I got from.

Capacity: 8.4 amps. An upgrade to the original, the 18176 Modulite harness offers more peace of mind by including circuit protection to safeguard itself and the tow vehicle from harmful electrical shorts and mis-wire situations. Rated at 4.2 amps for the taillights, 2.1 amps per stop/turn.

What is a ModuLite?
A ModuLite is a trailer light power supply module which provides power to the trailer lights directly from the tow vehicle's battery. By powering the trailer lights in this manner, the tow vehicle's tail, turn and stop light circuits are not exposed to any additional loads.
Why Is This Important?
In many cases the tail, turn and stop light circuits of today's vehicles are connected with light gauge wire, designed only to carry enough current to supply the lights the vehicle is equipped with. Additionally, some vehicles are equipped with sensitive electronic devices, such as "lamp-out" sensors, which are designed to monitor the vehicle's electrical system and warn the driver of problems with that system.
The additional load of trailer lights on these devices can cause them to react falsely and in some cases may lead to their failure.
Which Vehicles Need A ModuLite?
Is the vehicle equipped with any option packages that include a lamp-out sensor or other electronic devices that could be damaged by attaching trailer lights directly to the vehicle's electrical system? If so, a ModuLite is required.
Is the trailer being towed equipped with more that one light assembly per side? Does it have clearance lights, dual tail, turn or stop lights or any other equipment that will impose an extra load? If so, a ModuLite is required.
Is this the only trailer the driver will ever tow? Consider future requirements as well as current ones. In future applications, a ModuLite may be required.
Are There Other Ways To Determine The Need For A ModuLite?
Yes. Vehicle manufacturers caution consumers against adding additional loads to electrical circuits. Consult the vehicle owner's manual when recommending trailer wiring. The following are two examples from owner's manuals:
Jeep Grand Cherokee
"Do not connect a trailer lighting system directly to the lighting system of your vehicle. Use an approved trailer wiring harness. Failure to do so could damage the vehicle electrical system and/or result in personal injury."
Dodge Ram Pickup
"Towing a trailer equipped with more than the standard lighting (turn, tail, stop and back-up lamps) may cause an abnormally high electrical draw through the headlamp switch, causing the switch to fail."
Does A ModuLite Take The Place Of A Taillight Convertor?
Yes. ModuLites are designed for use on vehicles that have separate tail, turn and stop light circuits and converts them to standard trailer light wiring configuration. ModuLite and ModuLite HD also feature a hazard flasher override circuit. If the hazard flashers are engaged and brakes are applied, brake lights will be shown on the trailer. This is an added safety feature that most taillight convertors do not provide.
Can I Still Use A ModuLite If I Don't Need A Convertor?
Yes. They can be used on any vehicle that requires a reduction of load on its electrical system.
What Other Features Do ModuLites Provide?
Because a ModuLite receives its power directly from the tow vehicle's battery and not the turn signal circuit, the need for a heavy duty turn signal flasher is eliminated. Their advanced circuitry provides maximum trailer light brightness.
How Long Does It Take To Install A ModuLite?
Approximately 30 to 45 minutes depending on the difficulty of running the power supply wire from the battery to the rear of the vehicle.
