Intermittent
About a week after adding bright box I found that the passenger side lights would blink on and off while on brights. Called Geno's and they mailed me a replacement box. It has been over a year since I replaced the box and have had no problems. Like most electronics, I think that if you have a problem it will show up in the first few weeks.
As poor as the lights are on our rams, I would not want to drive at night without the brightbox I am tempted to add driving lights as the lights are just marginal with both brights, dims, and the fogs on.
