I've tried searching and I can't find my answer. I just ordered a 6500k plug and play hid kit and I wanna use casper shields, if possible, so that the glare isn't as bad. I've heard that you CAN use the shields with H4 bulbs, but you just have to force the wire that holds that bulb in down pretty hard. As long as it works, I don't care. But I've also heard you can ONLY use them with D2S and D2R bulbs...I don't see how that could be but someone please let me know which is right. Im hoping I can use em...
