If the LED relay has this type of "R/C time network" inside then it should be the same deal. Just play with capacitor value. Try not to go too far off from stock (don't replace 2300uf with 1 farad!!! lol might be 5 minutes before you get a blink!) and be sure the caps are rated 12-16v. I don't know how the LED systems work yet, I don't have any installed and running and have not researched it.
