just wanna try making a simple light worthy for offroading at night in the local trail....wanna ask if anyone has a step by step guide or general guide/manual around to help? i am new at this DIY light stuff (i kinda suck at electronics) but have some experience with machining and plastics. Main reason is i cant justify spending a significant amt of cash on lighting and i would rather DIY and learn some skills at the same thing. Thanks in advance!
