6 V DC to 4.5 V DC for bike lights (LED)?
I want to convert some ready to use LED gadgets for illuminating the bike and the road during these dark days. Many of them use 3 button cells or AA(A) batteries.
A small circuit board in the head light (have a huge motorcycle front armature ready) must convert the voltage. When I look for a 'buck puck', it seems that this lowering step is too small for what's available. true or not???
