19 December 2012 Question by: Rapid Customer | Product code: 56-1450
Q. do i need resistors to run my leds of my model railway 12volt supply my leds are L-7104GD-12V AND L-7104ID-12V, and if so which type and size
A. Hi Kevin, thanks for your question. No resistor is required if the LEDs are 12V and the supply is 12V – it is only if the supply voltage is greater than the LED voltage that a resistor is required to “lose” the excess voltage.


08 March 2012 Question by: Rapid Customer | Product code: 55-1909
Q. would these led be suitable for model making with direct 12v supply eg (scalextric cars )
A. Thanks for your enquiry. Yes these will be ideal for this application.
