Every hid kit I've had does that. The ones I have now actually have a reg halogen bulb attached. So now when I hit my brights it sorta turns into a reg bulb.......really dim compared to hid. Lol. I use this nifty feature when behind a cop or just showing common courtesy to on coming traffic. I have hids in a stock housing so it basically looks like an inferno coming at you. Lmao
