Cycling Helmet with LED Turn Signal Breathable & Comfortable Intelligent Safety Helmet Waterproof

When I use the small box that controls the turn signals (the remote control) that sits on the handlebars, an LED lights up when I press one of the turn signal buttons, but it goes out again immediately, so then I don't know if my turn signals on the helmet (the back of the helmet) are on or off, because the LED in the box has gone out again. I think my helmet with the "remote control" is defective. The LED should probably light up constantly until I click the button again, because otherwise it's not possible to know if the turn signals are on or off. Now I have to take off the helmet to check it. Turn signals are only on the back of the helmet and not on the front. Useless to only have turn signals on the back of the helmet. Why not have turn signals on the front of the helmet as well?? The helmet feels half-finished as it is now, with nothing to indicate (or sound) when the turn signals are used, so it is not possible to know if the turn signals are on or off. Then there is something hard (like a screw or something else sharp) pressing on one spot in the helmet. I try to find the sharp object behind the foam in the helmet, but can't find it. It hurts when the helmet is on the head in one spot. The helmet has 3 different modes but two of these are useless, because only the rear light flashes in different patterns, while the front light is off in these modes. Hardly useful modes, when the light in front does not shine at the same time as it flashes red in the back.
