[QUOTE="Knobdoodle"] [QUOTE="Jordan"] Could be everyone's right here, in a sense? The flashing only happens about half the time - on, off, repeat. So, duty cycle being ~ 50%, things run cooler. But if for any reason it gets stuck in "on", then.. [/QUOTE] Yes of course that's a facter Jordon (that and the fact that the resistors are probably underrated as Theo said) but there's a simple reason that the store-bought ones are encased on a big aluminium heatsink and that's 'cause they are dissipating a lot of heat! Go turn your indicator on and then hold the bulb while it's flashing; that's AT LEAST how hot the resistor will be getting [though the resistor will actually be getting a lot hotter] and George's will be getting hotter again because he's buggered up the resistance and made them too low (a normal indicator bulb is 21W or 10W but George's resistors are running 30W each). He's probably put them side-by-side too so that'll concentrate the heat even more! Now I doubt that George will ever even ride the thing long-enough to have a problem and I doubt that anyone here would care less if he did but it's important that readers realise that his estimates and assumptions are just guesses and shouldn't actually be trusted by anyone..... Plus; I just kinda' enjoy pointing out his stupidity....[/QUOTE] "Plus; I just kinda' enjoy pointing out his stupidity...." I think it is my turn for that, just hold your place in the line Clem. Boxer
