Our 2003 Ford Expedition had the turn signal go a bit wonky and started to turn off randomly...which is kind of a serious safety issue because if you go to slow down and turn left or right and the signal doesn't work, it could seriously mess up a couple people's day...Needless to say, I checked the online forums, found that usually the emergency flashers would stop working if the relay went out but we had no issues with that functionality. That being said, however, this was the cheapest, easiest and our most hopeful solution. Thankfully it worked! If you have a 2003 Expedition, the installation is pretty easy: Look at the bottom of where the gauges are housed (where it stops above the pedals) and you will see 2 screws fastening it in...9/32" is what the size is...Take both of those off, pop up the piece of plastic and it should come off (be gentle and don't crack it). Then, get on your back and face up...If you feel up and to the right (while facing up) and look towards the door, you will see a smallish black box that is about 4" long and it is parallel to you...Press both sides of this and pull up to take off the top and then you should see a blue relay. This blue relay, the stock one looked to be a little bit bigger but I think it was just a tiny bit larger. The fittings on the bottom were the same and even though it was hard to pull the original out, it was easy to put this one back in. I just put this in the same way the other was installed and then placed the black plastic cap over it, re-attached the plastic and popped the rest back on and tested it...voila'! It works perfectly!! I'll try to add some pictures but there was a good Youtube video on it. Also, if you are having trouble and your emergency flashers work, turn them on when you are looking for it and you should be able to see/hear and follow the noise to get you to see the relay. Good luck! I hope this works as easily and well for you as it did for me!! Review: Works fine so far in 2003 Ford Expedition 5.4L XLT - The turn signals on my 2003 Ford Expedition 5.4L XLT started to have intermittent issues. Sometimes they would work fine. Sometimes they would not work, but if I flipped the signal switch on and off, they would work again. Sometimes they would work, but you could hear the flasher clicking on a stuttering cadence. My 2003 Ford Expedition 5.4L XLT has incandescent turn signal and brake bulbs (not LEDs). And, I do not have turn signal indicators on my side mirrors. This CEC Industries EF27 12V Heavy Duty 5-Pin Electronic Flasher Relay for Incandescent Bulbs installed into the relay box fine (the fitment was good). And, it is operating fine so far. It is however, slightly quieter (the flasher clicker) than the original Ford relay - which is not a problem for me. ## Features - Heavy Duty | 5-Prong, Square Plastic Electronic Flasher | 12V | 162W | 0.27-12A | Durable at 600 Life Hours - OE (Original Equipment) Manufacturer with proven reliability - CEC lighting products are DOT compliant and meet or exceed SAE standards - Compatible with Incandescent Bulbs; presence of incandescent bulb necessary to function; Variable Load Range 0.27A to 12A Self-Adjusting to Lamp Draw.

But relay keeps ticking?** A: LEDs draw much less power. The reason it ticks is the flasher uses the voltage to trip and then reset. With the little power draw from your LED bulbs, it reacts like a bulb is out. There should be a specific led signal flasher you can find that works with LEDs. **Q: Is it compatible with 1999 ford expedition xlt or eddie bauer?** A: Yes, It will work. **Q: Will this work in my 1999 f250?** A: Should, pull your old one and compare. **Q: searching where is the location of signal relay flasher on a truck ford f-150 1998 4.6 come back R G?** A: Check your car manual or search Youtube. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This was a potential life-saver because not having turn signals work is dangerous! *by D***N on February 13, 2017* This was inexpensive, easy to use and worked like a charm (knocks on wood).

This item fixed my issues and it only took a few minutes to install. My Jeep had working hazard lights but the turn signals had stopped working and the old relay was making a loud buzzing sound when I tried to use the turn signals. To install this I removed the lower dash panel under the steering column, and the metal shield behind that, and found the bad relay in the left hand side. It was easy to find by turning on the turn signals since it made a loud buzzing sound. I put some di-electric grease on the pins of the new relay and swapped it out and now the turn signals work properly with no buzzing. ## Frequently Bought Together - CEC Industries EF27 12V Heavy Duty 5-Pin Electronic Flasher Relay for Incandescent Bulbs (1-Pack) - 5-Pin Flasher Relay for LED Turn Signal,FL27 EP27 LED Flasher Relay for Fix Hyper Flashing Issue,Turn Signal Flasher Compatible with Ford Dodge Chevrolet Lincoln Mazda Mercury - AUXITO LED Turn Signal Bulb 3157 LED Bulbs Amber Yellow 400% Brighter 3156 3457A 4057 4157 LED Bulb for Front Rear Turn Signal Light Blinker DRL Marker Parking Lights, Pack of 2 --- ## 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.us/products/11595439-cec-industries-ef27-12v-heavy-duty-5-pin-electronic-flasher](https://www.desertcart.us/products/11595439-cec-industries-ef27-12v-heavy-duty-5-pin-electronic-flasher) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-05*
