Question: they mention a diffuser lens: where can you get that
Document: Great light, fantastic customer service. Was contacted multiple times to make sure light was still functioning well. In addition, the seller went above and beyond to include useful tips and free follow-up offers such as extra o-ring sets and diffuser lens to spread the light beam out. This type of customer service is rare these days. Not to mention the light is fantastic. Buy this light, you can not go wrong!
The rechargeable bike light and all the updates i received are wonderful. I have been enjoying it. It is bright enough for all my night riding. I also feel that cars can see me, therefor I feel a bit safer.I am one of those that received a headband that is too small which I got a notice for and a letter stating they would be sending me a larger one the very next day along with a free lens diffuser and the o-ring set.
Lets face it, for this pretty cheap cost, you get a damn nice front light, free tail light and great customer service. You can not go wrong on this buy.Scottp.s.I did add Wide Angle Lens to mine, spreads the beam out more horizontally and less of a spot light. Gives me better control where the light goes and less worry about blinding people. (ya, it's that bright)
There are clearly no patents to worry about, because the LED and batteries are from outside suppliers, and the lens was invented sufficiently long ago that the patent has expired! Eliminate all the capitalized words and inflated price..."Bike Light- Made in USA! "PS- the light I bought works just fine.
The Bright Eyes rechargable headlight is POWERFUL!They gave us excellent customer service. One of the boxes (we bought two - one for my commuter bike, one for my son's) was missing a strap, and they sent me two immediately.The light is easy to mount, turn on/off, and the diffuser make the beam focus linearly, which is pretty cool. The beam without the diffuser is one of the brightest I've seen.
I am very pleased with the service! And very pleased with the light! The light was delivered on time and so was the wide angle lens I ordered with it. The light is Very Bright! I used all the settings including the additional settings by holding the button for 3 seconds. The wide angle lens takes a little bit to adjust, took about 3 minutes but once I did 'WOW'!
I can add a filter as the lens seems to stay cool. The housing gets warm but not hot, and this tells me two things: 1. efficient circuit design and 2. efficient heat dissipation which equates to long LED and battery life.The bonus red light was a treat and unexpectedly bright. 3 modes give you On, Fast Strobe, or Slow Strobe.
This thing is great!! !you will definably be seen at night, maybe even drunk drivers will notice.only thing, its so nice you have to take it off whenever you lock up the bike or it will get taken.
Just respond to my emails you will get after you purchased the product and say, "I didn't get an extra set of o-rings". And I will then send this out to you!! "So, there will be 2 sets of o-rings with this light and if you did not get an extra set, just reply back to Don's email.
If you are looking for a light honestly just get this one. I went out for a ride on an overcast night on a unlit path at 2am and i felt like I had a car headlight strapped to the front of my bike. This little thing is AWESOME!
