I understand this could have just been a bad bulb, however, once I installed this my high beam went out within a week. I immediately replaced it with a bulb from an auto store and haven't had any issues with that one. Because of this I can not recommend this bulb. I will say it had a nice, bright white color, better than stock but nothing mind blowing.
I bought the 10 & 20 degree light patterns. They were very easy to install on the forks using the included brackets. Ran the wires to the ignition so they're always on when the bike is on. They work great and give out lots of light to see deer and other critters by the roadside.
Seem good so far, although haven't tested in the rain as yet. Easy wiring, glow well at night, easy to use on the fly. Used them for Dualsport bike for accessory LED lights. Like them better than toggle switches that can easily be bumped on.
