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.

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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/3761575-tekonsha-119147-modulite-hd-protector-trailer-light-power-module](https://www.desertcart.nz/products/3761575-tekonsha-119147-modulite-hd-protector-trailer-light-power-module) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-16*
