10 years ago I put in a Xenon bulb. It was slightly better than stock. I am sticking w/ 55/60watt- NOT changing wattage. Many manufactures claim better / whiter light output. BUt I find some of this to be just advertising hype. So , what if any 55/60 bulb have any of you used that made an Obvious or dramatic difference in lighting up the road ? No- I am NOT changing to HID. I am only interested in doing a simple change.
