Vehicle Testing Program

At Diode Dynamics, we regularly have the need to test our lighting products directly on vehicles, to confirm fitment and function. We greatly appreciate our customers who are able to support us in this way!

Testing usually takes 1-4 days. We ask that you drop off your vehicle at our facility in St. Louis, Missouri. A rental is provided if necessary!

All media, photos, and videos generated during a testing session remain the property of Diode Dynamics for use in advertisements and product listings - but copies can be provided to you in high resolution, for your use in any way you'd like!

At this time, we are not able to provide compensation for vehicle testing. As a "thank you," our goal is to leave test vehicles with any products that we were able to install. This may include replacement LED bulbs, halos, modules, lightbars, or other products depending on your vehicle. However, we cannot guarantee that any product will be installed, and as such, we cannot guarantee any products or compensation as a result of vehicle testing.

Vehicle testing is limited to local residents of St. Louis, Missouri, only. Due to logistical complications, we cannot test vehicles that may have driven from out-of-state, or may be passing through.

If you would like to "add your name to the list" as a potential candidate for vehicle testing, please fill out the form below. If we have need of your specific year and model at any time in the future, we will be in touch!
