I'm about to wire up various lights is wall yard lights, exterior building wall lights etc. These will be powered from a seperate Accesory BUS. My power supply will be a 12 volt DC Gaugemaster type. My lights ( mostly ) were bought from China ( we honest supplier ) and I know they need to be down rated with a resistor before connecting to a 12 volt supply. Am I right in saying that it is usually a 1 K resistor that is used? Cheers Toto
Yes 1k for starters, but you may need to increase this if the lights are to bright. Best and simplest thing to do is make a little tester rig, chocolate block with 1k, 5k, 10k, 30k, 50k, resistors pre wired and then just add your light to each terminal and see which you like the best. Note. Red LED 's will need a higher resistor value (I'm thinking buffer stops here with a lamp on top) Kim
