Step 2: bulb is a GE 502...numerous bulbs will work.

These can be bought in packs of 6...
I have no idea where to get a 6v battery. Nice idea though!
You can get them at Lowes<br>
Old larger flashlights have them. but, if it works i guess theres no point in getting just the battery, lol.
6v batteries are normally available from hardware stores, camping stores, supermarkets etc.
the good thing about these battery are that they have a nice life cycle.
The interesting thing about these is what is inside. Most of them are just four "D" size batteries in the one easy to use carrying case. The ones I have seen would have enough room inside for the light and connector. Need to go get one now and "experiment"
This is an old riverbarge thing for peep lights on barges stowed in fleets.Id suggest making friends with a deckhand or mate on your local river,they carry cases of these batterys and lights.Bribe items such as smokes go far but a friendly gal showing her bits as you boat by can get you a case of these real easy.Remember these boys are out there for 20-60 days with no women.Just saying ya know.
If you want it with a focused beam, get an old reflector and knotch it out where the + spring will go and slip the center hole over the - before installing the bulb.
