2023 Gladiator Sport - switchback turn signals do not illuminate the white LEDs

[yitbos]

I've been scouring the internet and have found virtually nothing on this topic, other than lots of ads for switchback LEDs. Here is what I have.

• A 2023 Jeep Gladiator Sport with halogen lights
• I upgraded the headlights, backup lights, fog lights and DRLs using LasFit. All are working exactly as expected with no issues.
• Added LasFit switchback bulbs for the turn signals and when I turn on the turn signal I get the amber flashing but no white LEDs illuminating.
• I've tested the bulbs on my bench with a 12V power supply and the white LEDs do work.

I've found a couple of refences to needing something flashed at the dealership to work. Also found one reference (but can't locate it now) to a wiring harness splice that has to be done. I've put these same switchbacks in my Chevy Colorado and they work perfectly showing both colors when the turn signal is activated.

Any thoughts on what's needed here? The Taser JL Mini looked like it might help with the issue but I'm not convinced that's the fix based on the comment regarding the wiring harness splice. Though I am interested in the Taser Mini for a couple of other features.

My last resort would be to go all amber LEDs for the turn signal but I'd really like the switchback if I can figure the issue out.

Thanks for the assistance with this one.

The turn signals are single filament from the factory. You only have one hot wire to that bulb.

what I would do is but the pigtail for the bulb and splice it in using the DRL wire from the DRL bulb to power the white light. Splice the other 2 to the original connector with whatever method you choose.

Thank you for the reply and Suggestion jar_eee. Is there a wiring harness diagram link floating around for both of those connections that I could reference to figure out the best way to splice those wires together?
