This is conceptual, I don't know whether it will work or not. Fountain Head below with LED attached.
Break down of fountain head. That holed down spout may not be needed.
Upper cap, where I drilled a 5mm hole for the LED. I may need to use T10 Blue LED which is more powerful.
Bagful of goodies, LED Amber in colour and some load resistor from previous project. It's hopeless I need Blue LEDs.
Testing LED in the cap, amber and it's not bright enough.
And here it is in the dark, no way an insect can see it. May need to do some other way. What if I use those car waterproof light strip
