    Hi

    Thanks for the info on the lights, I’m going to go for the battery ones. Just 1 question, I’m fitting them initially to some 2 bil/Hal units , early 60’s . Should I fit warm white or amber? I’m thinking warm white as amber might indicate gas lights?

    thanks

    Brian

      Warm white with a resistor to dim it down a bit.  It is worth trying different values as the brightness is your personal preference.

      Resistor in Series I guess, what kind of value, I havnt a clue without forcing my brain back to ohms law, you just need to get a voltage drop is that right?

      thank you for your help

      I'd try a 1K ohm in series with the LEDs

      placing two 1K resistors in parallel using Ohms law is equivalent to 0.5K or two in series is 2K as below
