Parts of relays have started to rust after 2 months. One of the relays came faulty and sparks. This could cause a serious issue.

Buen producto,funcionando a la perfección, instalación de baja dificultad en la XJ,solo fue necesario tirar un cable desde el tablero para conectar las DRL al encendido,y con su propio switch de encendido/apagado,en mi caso tome la corriente que alimenta la radio ya que lo tengo instalado directamente a la bateria.solo quedaria pendiente esperar a ver como sigue funcionando con el tiempo.
