So me and my buddy got bored and decided to try to make a light bar so we figured it would be quite easy make a casing with something inside to reflect the light and make it enhance the light have like 10-20 little 2 pin led bulbs run all the bulbs into one big positive and then have one big ground mount it as a bar and use it for **** hunting offroading etc.... Thing is I am like electrically challenged it seems easy but it seems like its too easy.. would those bulbs drain my truck battery.. is there something im missing it would all be run on a toggle switch. If there is something im missing could someone explain to me how it works in simple "uneducated" terms please thank you very much.
