Great deal
I have a car with a HID kit that originally came with a harness just like this. The controller failed on my kit so I bought this one, basically for the controller. The quality of wires was good, good insulation, and unbeatable value for the money. This is a good deal if you need a harness. Controller worked perfectly, also.

Cheap and awesome
Have been using it for over a month now and it lights up every time. Really compact and easy to install even for DIYers. Material quality exceeds my expectations.

Si funcionó
Si funcionó, tal y como lo promete, lo use para hacer un conversión de faros H9 halógenos a HDI originales para F150 2013 quedó excelente y funcional, muy buen producto, mi proyecto fue hacer un F150 Platinum Single cab Pero la base que use fue un XLT que no tenía faros HDI de fabrica y este producto lo resolvió, lo recomiendo aunque ya en un futuro hablaré de la cuánto tiempo de vida tiene esto aunque por el momento está excelente 👍
