I have a 21 street bob that I bought an aftermarket headlight for and needed this adapter to make it work and so far all is well. Plug and play and real easy.

I purchased these to replace the set that came with aftermarket headlights for a 2014 jeep wrangler. One light was flickering and sometimes wouldn't work at all. Found corrosion on the h13 side of the plug. The h13 side of the plug isn't sealed and allows moisture in, creating corrosion. These harnesses are the same way and I added some electrical tape to prevent most moisture from corroding it. Other than that, they work flawless.

Need to have this adaptor to go from stock to 3rd party. Ultra limited 2015.You do need to change the blue and white wires though.

Perfect fit, great value, easy to install, good quality, much brighter than stock light and performs better than the harness that came with the light

The adapters work great, but I wish someone would make the adapter with the filter piece for LED's being used on an older Jeep!

Did not have to use as I bought anti flicker adapters for replacing my jeep headlights.Easy return but seem to be qood quality and correct parts. Thought this would help for the negative reviews out there

This works great when adding a led headlight to your Harley. Just be aware that you will need to de pin the three prong and install the two positive wires opposite from how they arrive. This seems to be a common theme for the led conversions. Several videos on line to show you how. Still easy and works great.
