## Description

ModuLite HD Power Modules use a direct connection to the tow vehicle's battery to power the trailer's stop, turn, tail and running lights without overloading vehicle electrical systems. Use a ModuLite module when: your trailer has more than one light assembly per side, and is equipped with multiple clearance or running lights; if tow vehicle tows a variety of trailers; if tow vehicle has 'lamp out' sensors or other sensitive electronics that could be damaged by increased electrical draw. ModuLite has integrated, re-settable short circuit and overload protection - safeguards itself and the tow vehicle from shorts and wiring installation mishaps. Rated at up to 4.2 amps for turn/stop circuits and 7.5 amps for the taillight circuit. Works on vehicles with pulse width modulation (PWM) taillights, ensuring full brightness of the trailer lights during operation. Adapts import and domestic vehicles with separate turn and stop lights (3 wire system) to standard trailer taillight wiring (2 wire system). Compatible with either LED and/or incandescent bulbs on both tow vehicle and trailer. Will not work with vehicles that have a low-side switch or multiplex lighting system.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Way cheaper than a Integrated Power Control Module
  

*by D***Y on Reviewed in the United States on March 17, 2022*

I put this in my 2004 dodge 2500 because the internal, non changeable relay that controls the left trailer break light went out in the IPCM. An IPCM is over $1000. Instead of using the splices that came with this (not good under the bed of the truck where water splashes up), I stripped, crimped and used heat shrink like the factory bed harness is built.The unit works flawlessly, and a much cheaper fix for an older truck.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Truly excellent product
  

*by M***L on Reviewed in the United States on January 15, 2020*

Modulite was very compact, well assembled, and the kit came with all necessary hardware for a most excellent installation. Being a reliability - safety kind of guy, I did cover all wiring with Nylon 6-6 split loom, SOP for vehicle OEM's.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Installation of a 7-pin vehicle-side plug made easy
  

*by C***S on Reviewed in the United States on March 5, 2019*

This was an easy install - taking the vehicle four-lead wiring to the trailer three-lead wiring.  The install took about 10 minutes as I had already run the wiring, I just needed to put it between the vehicle wiring and the 7-pin outlet on the bumper.
