Has tail light feeds for both sides . *by K***R on Reviewed in the United States on May 17, 2024* This has separate tail light wires for both side (brake and parking lights). Some harnesses want you to run an additional wire across the trailer for parking lights. Not here. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It's a wiring kit *by M***E on Reviewed in the United States on May 13, 2024* It's a good kit, wire's could be thicker and some heat shrink connector's would be very nice for a water tight seal. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Wiring *by R***. on Reviewed in the United States on June 24, 2024* Perfect fit for my trailer. easy install --- ## 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.tn/products/455059499-25ft-4-wire-4-flat-trailer-light-wiring-harness-extension](https://www.desertcart.tn/products/455059499-25ft-4-wire-4-flat-trailer-light-wiring-harness-extension) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-22*
