How do you get the back light to turn on? The front light works but the rear light doesc\\

To turn the light on for the very first time you have to remove a plastic strip by pulling on it. Most likely this is the problem for new users. After that step you simply push in the circle light on the back of the helmet. One push on the circle lights up the red LED lights. A second push switches over to the yellow LED lights. A third push on the light circle will light both the red and yellow LED lights together. A fourth push will blink the lights. The fifth push will turn the lights back off. There are batteries that may eventually need replacing. For new buyers this is not likely to be the problem.

After removing the plastic protection of the battery, just press the center of the red disc.

As I recall, when I first got the helmet, there was a clear plastic battery tab that had to be removed before the light could be turned on. Then, place your thumb in the center of the lens (gripping the back of the housing with your forefinger) and squeeze... once for steady amber; twice for steady red; three times for steady amber & red; four times for flashing amber & red; five times for "off". The outside ring of the light housing is used to adjust the fit of the helmet... counter-clockwise to loosen; clock-wise to tighten. I hope this helps. Safe biking...

to get the rear light to work...press the light itself if there is a plastic strip you need to pull it out for the light to work. you may need to put a little pressure on the light to get it to work. i have a couple of these helmets. one of the helmets i had to unscrew the rear light cover and reposition the batteries so they were touching the elements inside after that no problem.

are you sure you connected the lead to the back up lights so it would know when you went into reverse? You could also try to reverse the inputs.

Mine does the same thing and it works perfectly - my suggestion is don't worry about the lights - also, sometimes you have to give the system time to change so don't be in a big rush - good luck, I really like it.

I just clipped my light to one of the rear brake wires at the back of my seat & it has stayed on & not fallen off. Best of luck w/yours. The light is small but is quite visible b/c of the light output...it is very bright.

Mine did the same thing, I removed the capacitor (round black cylinder on the back) and it works perfect now, steady and bright.

Make sure battery top is put on and turned to match arrow. Mine didn't work either until I figured this out

I checked online and asked how to determine if my keyboard has a back light. I pushed the Fn key and space bar at the same time and it did not enable or disable any light. I assume that there is no back light on the keyboard.

Jose, return it for a new one. That is exactly what happened to me. The second light works great! I have a chev silverado and I put the light under the license plate in front. Looks and works great!

Mine is not backlit and the F5 key didn't "turn on" the backlit keyboard option (as another poster mentioned). My F5 key turned the mouse off and on.

I have the same question. Looks like the lights are gone with out notice. In fact I thought it's not working since there to light, but looks OK afterwards. What is disturbing is that as an owner of old model I was not aware of the missing lights...

on the underside of the light is a small pin hole. put the wire key into the hole and push - that turns it on. :o)

Make sure your connection to the charger is locked tight. Push it again then check lights.

You have to push the pilot light button in and light it and hold it in until when you let it go the pilot light stays on then you twist the button on the back to the on position.

Sounds vaguely familiar. If you press the button, does the light turn on at all? Have you tried removing the batteries, waiting a few moments, then reinstalling the batteries? If it's the problem I think it is, I think it's the light's circuitry going into a protection mode. When you charge the light, do you plug the charger cable into power source, then plug the mini-USB plug into the light? Or do you connect the light to the cable first, then connect the cable to a power source? If the former, then I suggest switching to the latter to avoid the problem. I suspect it's an issue of the powered cable touching part of the light it shouldn't if you're not inserting it "cleanly" into the charging port, tripping a protection mode.

I have had this problem a few times. After the cussing and the startle response have settled down, I slapped it back on and pushed it extra hard, that seems to work. I also noticed that the little light on the front never comes on, so I'm wondering if the unit is simply defective.

Turn the bezel around the bulb. This may take a try or two until you get the feel for it. If that doesn't work, there's a battery or bulb problem. I love the flashlight!

perhaps u connected to the rear running lights rather than the rear back up lights
