100% on the plug and play not feeling quite accurate here, but Im curious what other electrical issues did they encounter?
Im not totally surprised by the hyper flashing, us XLT folks are going from a bulb that has a higher resistance than those that already have LED headlights. The majority of the trucks at my dealership are not incandescent bulbs so I would draw a conclusion that Alpharex likely used the most common app and tested these primarily on trucks fitted with the stock LED headlights.
Im kind of disappointed that may have been overlooked though as its not an uncommon issue. Also, regarding CJCs response, I assume they mean resistor and not capacitor. Which also suggests they are familiar with this common issue and really makes me wonder even more why it wasnt prepackaged as an optional component.
Frustrating
