2 hours after the installation of the IID, my left front lights went out. Called the installer and they asked for me to come back because it might be a fuse blown. Went back and they looked at the fusses but couldn't find any blown. So they said it might just be the bulbs... the entire set... oaky whatever I'll replace them. Fast forward 2 weeks and now none of my lights work and I am unable to get anyone to service the because of COVID and the fact that someone will have to blow in it every 5-55 mins. Asked if there was a way that they could disconnect the it and put it in maintenance mode... nope. In fact I would have to have it uninstalled (need a court order) and then have it reinstalled all at a cost. so, I have a truck with 40k miles that I cannot drive unless the sun is up. I highly recommend that you do not use this device and search for an alternative to save you the headaches and drain on your finances.
