If no anti flicker included in the Headlights.. PROGRAMMING is necessary.. This can be done with Jscan..an App you install on your smartphone and a OBD plug in donagel... check their site: www.jscan.net
YOu will find it much less expensive than Tazer and it does ALOT. (what I Use)
The Elite and Elite Max headlights are completely plug-and-play with both factory halogen and factory LED-equipped Gladiators.
Source: Me, having installed them on two factory halogen-equipped Gladiators with no extra programming or products needed.
Source 2: The description of the product directly from the Diode Dynamic website. Which states, in part,
"Plug-and-Play Installation. These headlights were designed to be a direct replacement for both halogen and LED-equipped Jeeps, in all trim levels. Simply remove your factory headlight assembly and ours will bolt right in its place."
