Pair of High Four Adapter With H4 Plugs

Good product, great quality, and fast shipping

Cool concept, used it on non vision x lights but didn’t work, one day I’ll hopefully get some vision x head lights and have these ready to go

I installed these on a Jeep TJ with Vision X headlights. These adapter are great and work as advertised. The H4 plug on the Jeep harness is terrible. All H4 plugs seem to be terrible. They are not made for wet or Moist environments. The Female end of the vision X plug has a porcelain isolator. All metal Spade terminals are fully exposed on all ends to moisture. This is just not an acceptable plug for an off-road vehicle in Washington state (it’s real wet here). I removed the H4 plugs and replaced with Deutsch DT. The black plastic housing in the middle of the high four adapter (Presumably, Containing a diode splice) does not look weather tight where the wires inter and exit. The splice may be weather tight inside this plastic housing, I can’t tell form the out side. Time will tell if the splice housing is up for the conditions. Thank you Vision X for making terrific lighting products!
