shift light

Post by screamer69 »

im thinking about putting a shift light in now so i just want to double check a few things

according to diagram bottom one of the three

i use js7 (pin10 ) circuit on the m/s and alter the 220r to suit the led used ??

so if im right as im not that briilent at electronic ( noooob but willing to learn )

if i was to use a 12v led then i dont use 220r ??

but looking at the diagram it works by triggering the ground is this right
instead of putting power to the led its just grounding the led once its got to the right setting


cheers

and sorry for sounding like a nob ( we all have to learn some where :RTFM: )

Thats right.Most electronic switching switches the component to ground to complete the circuit.A 12v led will have the required resistance built in.Most std leds have a rated current and the resistor must be selected to reduce circuit current to this level.

Ohms law current (I) in Amps = Volts / resistance in Ohms.

so I=V/R or V=IR or R=V/I for whatever you want to find.
