Thumbs Up
Good quality, and fast shipping. Plug and play to convert my stock 2021 street glide headlight to an led light.

High and low beam are backwards
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.

Never enough bike parts
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

Failed after a few months of use.
I have placed 2 orders total for BICYACO H13 to H4 Adapter Headlight Adapter Connector. 2 connectors each come in the box. 3 connectors have failed after only a few months of service. #4 has intermittent problems now. BICYACO NOT GOOD. ZERO stars.

Not weather sealed
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.
