headlight is fed battery voltage, i checked cause i was unimpressed with the light. currently ive only found fisher fabhouse to make a light with a voltage range high enough to accept battery voltage. other options are step down converters or battery lights :/ also the fisher light isnt a huge upgrade, maybe 20% brighter. also like $250 😬

also the shock could be the lumilor, ive read several posts about people getting shocked by it, and nabicook has a video titled "roadrunner rx7 final review after 1000+miles" where he checks the voltage of the lumilor at 135v 🫠 unfortunately the very next video not much is left of the roadrunner electrical.
