Would buy again. ### ⭐⭐⭐⭐⭐ Good Quality, Heavy Duty. *by K***N on April 21, 2018* This is a really nice heavy duty relay. I put it in my 2017 Superduty to run my auxiliary backup lights with my upfitter switches. With this relay installed I can run the auxiliary backup lights in two modes, ON when ever I want (even with the truck OFF) or make them go ON and OFF with the factory back up lights. Works great and I didn’t have to use a diode. My configuration uses two of the upfitter switches in the truck. The mounting bracket worked out nice. This relay is water proof as well, has a nice ribbed torturous path gasket. 7/16/20 Update: Two years now and still working, no issues. Thumbs up! 7/25/2023 Still going strong! 05/21/24 still working!!! I bought two of these on my original purchase, one as a spare because that’s what I do. The spare is still sitting on the shelf in my basement. ## Frequently Bought Together - True MODS 5 Pack 5-Pin 12V Bosch Style Waterproof Relay Kit [Harness Socket] [12 AWG Hot Wires] [SPDT] [30/40 Amp] 12 Volt Automotive Marine Relays for Boats Auto Fan Cars - 10 Gauge Fuse Holder - 10 AWG Inline Fuse Holder with 40 AMP ATC Blade Fuses (4pack) - MCIGICM 12 AWG Inline Fuse Holder with 30A ATC/ATO Blade Fuse, 5 Pack --- ## 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.ec/products/43062557-true-mods-5-pack-5-pin-12v-bosch-style-waterproof](https://www.desertcart.ec/products/43062557-true-mods-5-pack-5-pin-12v-bosch-style-waterproof) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-21*
