Best investment ever!!

<p>If you own a motorcycle this is a must have not only for the amazing light that it produces but for your safety as well. It is probably 3x brighter than stock and has reduced voltage draw. Don't be fooled by cheap imitation products piaa construction is superb and top notch worth every penny i highly recommend</p>

PERFECT. Finally someone made a top of the line LED bulb for a regular halogen housing!

I have a 2015 Honda CBR500 and it had a regular ugly halogen bulb. When looking for a replacement i Immediately started looking at hid's because that is what I have in my vehicle and the led options on the market just didn't seem like the technology had come far enough to compare. The only problem was that with hid's heat can be a huge issue. (trust me melted my brand new grand Cherokee fog light housings in 20min). Anyways as I was looking at all these no-name brands I thought I'd just see what piaa had to offer because they have always been top of the line in any of the lights they make. To my surprise they recently launched these led kits, and there designed that you can put them in a regular halogen housing and not blind everyone around you. The lights are awesome! Great look and color. Super high quality, u can tell when u pull them out of the box. Easy install and high and low beam. Even in high beam the light is pointed perfect. 100% a situation where u get what u pay for. No heat issues. Way less draw from the battery. Twice the light as before and looks great. Anyone wanting a super high quality headlight replacement for there motorcycle (or car) I highly recommend. Have had it in my bike for about six months now and not one issue.
