Circuit Demon LLC

Awesome customer service and extremely fast shipping. Order a set of switchback LED bulbs for my 2022 WRX. Package came neatly and safely packed. Bulbs are amazing quality and work great. 10/10 on customer service, product and shipping! Highly recommend.

Contacted Circuit Demon to help me source a set of headlights for me. I'm in Australia and for whatever reason is super hard to get them here.
Ben was extremely helpful and got the headlights and there diy retrofit kit all lined up for me to get shipped all at once.

Then when I ran into a few issues modifying them gave me all the answers I needed.

Thanks again 🙂

This is a most interesting place.....I contacted them about an open house to inquire if everyone was welcome.....immediate response and a welcoming invite.....impressive so I showed up having no idea what to expect...... pleasantly surprised, entertained, and even though I am almost 4X older than the majority of folks there I never felt out of place......
I still need to talk to them about Diode Dynamics lights

Open house was super impressive. Will be using their services soon

Fantastic quality headlights. Use amazing parts and know there stuff. I bought the DIY kit and ended up getting way over head with the install. When I contacted them they were nothing but helpful and provided a bunch of resources to help. Got it all together then contacted them about my high beams not working. Turns out they forgot a piece in my order and even though it had been over 6 months from my order they fixed it with promptness and sent out the part immediately. Got it a couple days later and everything worked as said. Mistakes happen and this is how a company should handle them. Overall very impressed with the quality, responsiveness, and professionalism. Will definitely be my #1 source for headlights for all my Subaru’s!

Jeff and Cody run the best custom headlight shop in the Northeast region I’d not the whole US. Although they specialize in Subaru headlights, they built my zx3 focus lights exactly how I wanted them. Always outstanding work

The whole team at Circuit Demon was great to work with. It is clear that they truly care about their customers, and the pride that they take in their work is unparalleled.

The absolute GOAT of custom headlights and retrofitting! 17 WRX Got handed the sauce from these guys, from housing repainted, c lights upgraded and slimmed, halos added, demon eyes, retro fitted second set of projectors where the old high beam was with a bi xenon, custom acrylic plates with switchback, honeycomb etching on outside and fogs, and custom circuit demon logo etched into inside projectors! Fog lights also upgraded to morimoto leds! The insane creativity and work and quality they put into their headlights is second to none. Working with you every step of the way and making sure it's exactly what you want! Customer service is top notch and they have always been there to help me whether it's upgrading parts or answering any questions at all. The Circuit Demons are real Homies for life yo

Came in for an AOS Install and Spark Plugs. Great service, great team, I will definitely be back to see the guys at circuit demon for anything I need on my car

Circuit Demon hooked it up with these custom sharingan headlights. I would definitely recommend working with these guys, super knowledgeable and even more helpful for somebody who isn’t really tech savvy such as myself. Couldn’t be happier with the outcome

Best auto mod shop around, for any car modification and tunes

I have not received my product yet (and will update if need be when i do) but i wanted to give credit where its due. Circuit demon's customer service is top notch! Ive been in contact with an employee (Jordan) for at least a week talking specifics about the build of my headlights; when i can expect it, how much it will be, helping pick and choose additions. He has been extremely helpful and patient and answered my numerous questions fully (very particular person). If you like to know every aspect of a purchase before making it shop with them!

I've had Diode Dynamics C-lights done on my WRX here a few years back. Recently notice that the high beams will flicker whenever I uses the turn signal, thought it was the LED driver going bad and stopped by to see if they have one in stock that I could purchase and replace it with. Turned out Diode Dynamics no longer makes the older version(what i have). Jeff the owner was kind enough to give me a newer version FREE OF CHARGE and actually spent 15 minutes of his time installing it for me FOR FREE!

If you are local to these guys, definitely give them a visit, it was a great experience for me a few years back and again now. Seriously, give them a try, they won't disappoint you.

Great experience from start to finish. The customer service department responded to my emails very quickly. They really took time with me to help me decide exactly what setup I wanted. The finished product was better than I could have hoped for.

Great environment around the shop and interested in helping you.
Took on the task of a DIY project with some of their products and it turned out better than I ever could’ve expected. Even when I messed up or had questions about installation or what I did wrong on my end, the guys were super helpful and passionate about helping fix my mistakes.

Great customer service and their lights look amazing on any vehicle! Always pay close attention to detail as well and make sure customers are always satisfied. Would highly recommend!

Circuit Demon built the headlights for my 2015 F150 and they exceeded my expectations. This is not a headlight they typically work on but they absolutely killed it and I got so many compliments on them.

Best custom shapes halos on the market.

Not only does their product look amazing but also I had trouble with the wiring, but support walked me through the wiring and what each wire would do if hooked up, happy with the end product

Very good quality retrofit headlights , smooth easy process dealing with the company got exactly everything i could ask for with the headlights
