HI Mate
hope the picture works out, it's my homemade prawning lights. It's basically
just a low voltage halogen mounted on a cap (make sure the cap has cardboard in it to stop light coming through, usually about $2 from go-lo). Cost in total is about $3-$4
I normally use the 20w globes and a small gel cell battery (from Jaycar 7.2AH)
if going on foot. If in the boat, i just hook it to the boat battery and sometimes change the globe to a 50w one (although normally the 20w one is great)
