Well some of you already know my mania to make the watches are well lit

This is a simple and cheap

We did a system concept of this but with blue LEDs were not very good.





The diodes and resistors have cost € 3.45 and also we must shrink sleeves in my case of 2 diameters

Note that the diodes have the longest polarity is negative















The first case (left) isolates the terminal of the diode and resistance, then we put a cover and isolate the other diode terminal taking it back, then we put the other case we weld the diode resistance and isolate the remaining aa sight.












I have passed under the wire by passing it through the hole, so when goals faston connector cable firmly subject, so installation is very easy to undo.



I have soldered the negative terminal of the diode to the chassis and so put him to ground and clamping circuit that does not move.

Blue is the worst colour for readability at night, I think that green is the optimum sensitivity of the eye so the writing seems really clear.
