About Diode Dynamics
Diode Dynamics builds automotive LED lighting in the USA, from off-road pods and light bars to replacement bulbs, headlamps, accent lighting and infrared lights.
The first perk to grab is free US shipping on your next order, which comes from joining the email list, since shipping is otherwise priced by order size at checkout.
Diode Dynamics was founded in 2006 and traces its start to Paul McCain, who as a teenager soldered LEDs into a Hyundai Tiburon in a garage. Instead of importing and rebranding products, the company designs, engineers and builds as much as it can in-house, and a team of more than 80 now works from a headquarters of 70,000 square feet in St. Charles, Missouri, its home since 2021.
The facility runs automated SMT circuit board lines, a photometric lab, environmental test chambers and robotic sealing, and the company recently began optical injection molding for its own optics. Its quality management system meets ISO 9001:2015. Every employee completes a ten-week course covering 12-volt power, electrical theory and lighting systems. Diode Dynamics also takes on OEM manufacturing work, publishes vehicle-specific installation guides and fields a race team.

How to use a Diode Dynamics promo code
- Ordering by phone works with codes too: mention the coupon code to the agent while placing the order.
- Sign up for emails before you buy if you want the free US shipping perk, since it applies to the next order after joining.
- Current banner deals target specific lines, with 10% off Stage Series light bars, 10% off USA-built LED lighting, and 10% off roof racks bought with Diode Dynamics lighting.
- Plan the cart carefully before you pay, because placed orders can't be modified, only canceled before they ship.
More ways to save at Diode Dynamics
- Free returns on orders of $50 or more lower the risk of trying a new light bar, as long as it goes back within 30 days.
- After that, the 90-day store credit window still leaves room to switch products, though you pay return shipping.
- Skip expedited UPS unless you need it, because that fee isn't refundable once a tracking number exists, even if the carrier runs late.
- Orders over $300 currently add a free 20th anniversary patch.
