don't forget components and storage for them. unless you're limiting yourself to repair and analysis, you will also need breadboards to hold the components as assembled, and the appropriate tools and consumables to assemble the components onto the breadboards according to the mode of construction you choose: solderless breadboard, regulated soldering pencil, solder wire and paste flux at the minimum, also solder paste and tweezers and magnifier and regulated hot air hand tool and/or oven if you decide to work with SMT. the hot air tool is also useful at low heat for exploring temperature effects on circuits
sometimes you'll need at least two meters, to watch two quantities simultaneously. bench units tend to be a bit overpriced unless you're actually working with microvolts on the regular. I get the impression EEVblog Dave doesn't sell anything he wouldn't have on his own bench

supercaps are fine with lots of current in or out, in fact, DIY spot welders often utilize them for energy storage. but they are much less tolerant of overcharging, so you have to promise some things. if the alternator output seems tightly and promptly regulated, and desu you would probably need a scope or a spec manual to know for sure, a chinkshit 6S supercap module from alibay would be worth a try. just know that 100ms is a long time for an electronic component under stress

>If your LEDs have built-in current regulation like resistors
that's not regulation. this is regulation https://www.onsemi.com/pub/Collateral/NSI45020-D.PDF

>more retard-proof than a trimpot or dip switch
but less retard-proof than clipping out discrete resistors, if one-time programmability isn't an issue

unironically pic. cheap, cheerful, but effective
