I am trying to help a riding friend who has a problem with tail lights blowing.
Incandescent plus too much vibration.
I know we can go the Paul Goff route but with shipping it makes a very expensive, but good, solution - so...
I have a few LED array boards from eBay - at $3 cheap as chips - and very bright at 12V - https://www.ebay.com.au/itm/232389647269?euid=7ae8cb773101460799566ed081beae96&bu=43568365633&sojTags=bu=bu&mkevt=1&mkcid=7&mkpid=0&emsid=e11050.m43.l1123&ufes_redirect=true&ul_noapp=true
I have tested it at 9V and it appears to be about half brightness.
Next step finding an appropriate resistor to give that effect for the tail light on the bike.
Has anyone done this and know what kind of resistor size I should be looking at?
My multimeter shows open circuit if I try to measure the resistance of the LED board - so, stabbing in the dark.
I am not an electrician of any kind - just muddling my way.
Any constructive advice appreciated!
Cheers
