I'm looking to replace burned out instrument/indicator lights with LEDs as a project to learn more about electronics. I'm working on an indicator light in a switch now. The LED I have in mind is a 2V/60mA "5730 (5630) Red SMD LED Diode Light Surface Mount Chip 5.7mm x 3.0mm DC 2V 60mA 0.2W, Super Bright Lighting Bulb Lamp".
From what I've learned so far, I should plan on 12-14 volts from the car. My math tells me 14 V / 0.06 A = 233 Ω required, and 14 V * 0.06 A = 0.84 W minimum power rating on that resistor. Am I thinking about this correctly? What power rating can I safely use? Would putting this LED / resistor in place of an incandescent bulb affect the other bulbs on the circuit?
