Hope this helps. **Q: Do these have a built in diode?** A: Not for the led that is determined by the wattage of the bulb a 12 volt led 1156 should have the diode built in it. **Q: Can you leave the relay energized for long periods of time? I want to connect to the 'load' circuit on a solar panel controller.** A: The load would have a big affect on how long it can run. I have LED running lights wired in on my motorcycle which are on all the time so they can be lit for many hours at a time. So far I have not had any issues with these relays. A low load through the contact would allow it to be energized forever theoretically. **Q: What gauge is the wires I need 12 gauge but I have found normally they are only 14 gauge** A: On the set just received, three wires are 14 GA. (power and N.O. and N.C. wires). The other two wires (coil trigger) are 18 GA. rather than 16 GA. as indicated in one of the photographs........... also wish vendor supplied operation cycle rating, I know the rating is higher with a 30 amp load vs. a 40 amp load, but are we talking about 200,000 total cycles @30 amps or something drastically LESS???? ## Customer Reviews ### ⭐⭐⭐⭐⭐ a must *by D***S on 15 April 2022* ### ⭐⭐⭐⭐⭐ Excellent relays that all work! *by A***M on 17 September 2019* ### ⭐⭐⭐⭐⭐ Reliable at a great price. *by D***M on 15 August 2025* ## Frequently Bought Together - True MODS 6 Pack Bosch Style 5-Pin 12V Relay Kit [Interlocking Harness Socket Holder] [14 AWG Hot Wires] [SPDT] [30/40 Amp] 12 Volt Automotive Relays for Auto Fan Cars - irhapsody 5 Pack 40/30 AMP 12V DC Waterproof Relay and Harness - Heavy Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Automotive Relay - 10 Pack 14 AWG Inline Fuse Holder - 12V-DC ATC/ATO 14 Gauge Fuse Holder for 15A Blade Fuse --- ## 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.id/products/259049338-ols-6-pack-12v-dc-40-30-amp-5-pin](https://www.desertcart.id/products/259049338-ols-6-pack-12v-dc-40-30-amp-5-pin) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
