LED/switch DIY on euro

[learner]

hi .. all euro owner.
did u notice tat even the glove box is close, the light inside the glove box is still on??
so i did put a switch to it... so the light is ON only when you open the glove box... and i change the blub to 2 white LED...
i am goin put LED lights in the middle box and the coin box later as well

P.S. remeber you need resistor for the led...
use the formula below to determine the correct resistor

Resistance in ohms = (Supply voltage - 1.7) x 1000 / LED current in milliamps

so to operate the LED at 20mA, for 12V, use 560ohms
(12 - 1.7) x 1000 / 20 = 515 -> use 560ohms


here is the switch...

P.S. the light is much brighter than the pic below
