About this build
Mark G.'s 2026 Jeep Gladiator glows purple from underneath thanks to a triple-row LED Underglow Strip Kit in full color and white. Mark went with the solid version, so the color holds steady along the length of the truck instead of chasing, which gives the Gladiator an even, saturated glow from bumper to bumper. Picking the triple-row kit over the single-row version puts three rows of LEDs under the truck instead of one.
The underglow is wired through a Dual Harness, which gives two leads so more lighting can be added to the Gladiator later without starting over. The Gladiator's long wheelbase is made for underglow, giving plenty of frame to run strips along. Want this Jeep Gladiator underglow setup? Every part on Mark's build is in the parts list above.

How it’s installed
- Run the underglow strips along the frame rails and under the bed, keeping them clear of exhaust heat and the driveshaft.
- Mount strips to clean, solid surfaces and secure the wiring with zip ties.
- Keep all connections sealed and away from suspension travel.
- Wire through the Dual Harness, which gives two leads so you can add lights later.
