Instructables
To add a new light when you ride a motorbike is a plus for your safety. So...I had a small light decorative for my motorbike. Was gained some years ago before the LED attack. It had a small 12V DC lamp. I never used it and burried throuhgt the years. Recently I find it and after checkin that is works i decided to use it but replacing the 12V lamp with a bright red led of 1,7V. The replacement was really easy. After i decided to light it up using a cell battery of 3,6V i didn't add any resistor. Then I decided to place it on the top on my helmet. So for doing this we need some tools....

Hola, realmente creo que no es recomendable hacer un agujero en el casco. Debilita la fuerza estructural del casco y deja de cumplir la funcion de proteger la cabeza contra golpes. Quizás se puede acomodar la luz en la parte trasera, para que solo se vea desde atras, y no se tenga que hacer un agujero.

Hi, I strongly recommend not to make a hole in the helmet. It weakens the structural strength of the helmet, and it stops working protecting your head. Maybe, the red light could be repositioned in the back of the healmet, so its not viewed from the front, and the hole will not be needed.

(sorry for my poor english)

i don't believe a tiny hole of 0,2mm will damage helmets strenth....Anyway i ride a custom bike and i dont run over the 80km.....and iwill tell you a secret i am 43 and i used to ride motorcycles since be 17....as i had in the past accidents (and the helmet always on myhead) never helpd me in something.....and i had about 5-7 very serious accidents (thank god nothing serieus happened)

Helmet is really necessery for those who ride very fast.....
