OK thanks. I was hoping they also dimmed along with the headlight when the IAHB was enabled.I believe only the headlights dim in oncoming traffic if you have your Intellibeam Auto High Beam Assist enabled on the steering wheel, and you have your brights on. The DRL Adapters keep the DRLs bright all the time and do not dim when you turn the headlights on, as they do without the adapters. The minute you put the car in drive, the DRLs light up and stay bright all the time without dimming. The DRLs are not affected by the IAHBA.
