Junctionmad Posted September 8, 2017 Share Posted September 8, 2017 My MO with small LEDs is drill two small holes in something insulated the same distance apart as the led wires. Poke a feed wire down each hole. poke the led wires down the same hole as the feed wire. No soldering, easily replaced LED. I also slip insulated sleeves over the LED wires and prod the feed wires down the sleeves again to avoid the need for soldering. The right size holes should make detachable LED headlights for 00 steam locos do able if not exactly easy. Leaving aside the fact that the discussion is currently about SMD leds, why would you ever want " easily replaceable leds. the MTBF hours are such that they are typically a permanent fixture Link to post Share on other sites More sharing options...
