The original relays were sticky and soon the high beam relay failed. Since I put these in, no more stuck on headlights and everything is back to normal. Build quality looks excellent. If I need more of this type of relay, these are the ones I'll be getting. Review: Used for fog lights on 1997 Honda Accord SE Sedan - Used this relay after a cheaper one blew. So far it has lasted and has worked every time. The last one used to get 'stuck' sometimes so my foglights wouldn't go off with high beams but this one clicks every time and has yet to miss! Would recommend and buy again (although I don't think I'll have to!) ## Features - Quality assured products - Secure fit - Designed with the installer user in mind - Proven and Tested for durabilty and function in real world conditions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000P61E36 | | Best Sellers Rank | #992,596 in Automotive ( See Top 100 in Automotive ) #502 in Automotive Replacement Starter Relays | | Brand | Install Bay | | Coil Voltage | 12 Volts | | Connector Type | Plug-In | | Contact Current Rating | 30 Amps | | Contact Material | Aluminum | | Contact Type | Normally Closed | | Current Rating | 30 Amps | | Date First Available | August 20, 2007 | | Department | Electronics | | Is Discontinued By Manufacturer | No | | Item Weight | 1.28 ounces | | Item model number | E-123 | | Manufacturer | Metra Electronics | | Maximum Switching Current | 30 Amps | | Maximum Switching Voltage | 12 Volts | | Minimum Switching Voltage | 12 Volts (DC) | | Mounting Type | Screw Mount | | Number of Terminals | 2 | | Operation Mode | Automatic | | Product Dimensions | 3 x 3 x 1.13 inches | | Specification Met | ABS | | UPC | 617407323412 086429006557 041114288748 163121248574 | | Wattage | 360 watts | ## Product Details - **Connector Type:** Plug-In - **Contact Material:** Aluminum - **Contact Type:** Normally Closed - **Current Rating:** 30 Amps - **Mounting Type:** Screw Mount ## Images ![Metra Install E-123 Bay Tyco Relay 12 Volt 30 Amp Each - Image 1](https://m.media-amazon.com/images/I/51xMaSrDd8L.jpg) ## Available Options This product comes in different **Customer Package Type, Size** options. ## Questions & Answers **Q: do these usually fail after 6-7 years I have it controlling my high and low beams and my lights will turn off for about 30 seconds then come back on** A: sounds like you maybe running more current than the relay is design for. A head light on a car can use 20 amps or more. Two lamps and you would be over the 30 amp rating. **Q: I bought this b/c I need to run one remote 12v wire from my car stereo to several car amplifiers. Does it matter what terminal I use for each wire?** A: Your "supply" wire (Fused 12v from the battery directly typically) is going to always go to terminal 30. Your "output' wire will be terminal 87 to all of your amplifier remote on terminals. 85 and 86 are your switch path where one will get positive 12v (stereo output remote on trigger wire I believe) when you want to the relay to connect 30 to 87, and the other will get grounded. **Q: just to confirm, base on the diagram, this is SPDT relay right?** A: Yes, this relay is a SPDT 20/30amp. **Q: what is this for?** A: Controls electrical current. Keeps fuses from blowing. I use it with my running lights on my motorcycle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These are very good quality *by D***M on August 19, 2012* I bought these to replace the relays in my Ford Truck aftermarket headlight harness. The original relays were sticky and soon the high beam relay failed. Since I put these in, no more stuck on headlights and everything is back to normal. Build quality looks excellent. If I need more of this type of relay, these are the ones I'll be getting. ### ⭐⭐⭐⭐⭐ Used for fog lights on 1997 Honda Accord SE Sedan *by B***D on January 4, 2015* Used this relay after a cheaper one blew. So far it has lasted and has worked every time. The last one used to get 'stuck' sometimes so my foglights wouldn't go off with high beams but this one clicks every time and has yet to miss! Would recommend and buy again (although I don't think I'll have to!) ### ⭐⭐⭐ Just your basic Bosch-style relay *by O***Z on October 8, 2012* There's not a lot to say about this one. If you know what it is then you should know how it's used. I keep several on hand, I always seem to be adding lights to my vehicles. Buy the plug for it insead of using individual terminals for a much cleaner install and no hassle reconnecting it when you have to replace one. Instead of wiring it as the diagram shows you, consider connecting the switch lead to 12+ and putting your switch on the ground terminal. Done that way you only have one wire to run to the dash and it's a ground, not hot. Connect the other side of your switch to any convenient ground. Much safer and simpler. ## Frequently Bought Together - Metra Install E-123 Bay Tyco Relay 12 Volt 30 Amp Each - True Mods 10 Pack - Bosch Style 12V DC 5-PIN SPDT Interlocking Relay Socket Harness Base (with Wires) - HD Switch 12V 40A Waterproof Relay Replaces Tyco V23234-A1001-X036 - SPDT w/LED Indicator Light & Dielectric Grease --- ## 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.kg/products/4086192-metra-install-e-123-bay-tyco-relay-12-volt-30](https://www.desertcart.kg/products/4086192-metra-install-e-123-bay-tyco-relay-12-volt-30) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-02*
