/diy/ - Do It Yourself

i have a cheap dirt bike with no lights or indicators. all i want to do is hook up a neutral light to help find neutral when i stall (pain in the ass to find when hot and kickstart engine so required). im thinking about instead of trying to fit a small sla battery and making a bracket and everything, just using six 2.7v supercaps in series in a 3d printed case so that i dont have to try and fit a large battery just to power a 20ma led and i wont have to worry about a switch or unplugging it to keep from killing the battery (after a long long time).
>is this a dumb idea?
>do i need a resistor for the capacitor input or will the led and its resistor work since everything will be in series?
even though the bike has nothing electrical besides the ignition the engine has a power coil installed and wired as well as a neutral switch, so its all plug and play as far as that is concerned.
