Default Re: 12v battery

i use a 1hr quick charger for my rechargable tool battery that my lights run off of.
Cheap and easy,just like plugging your cell phone in to recharge it.

Wow, I can't believe that stuff is there already! You aren't going to be able to use automotive fog or driving lights, unless you want 1 hour of usability, and a week of recharge time. You'll be able to use a couple of bright 12V LED's though, and have it be completely recharged each day. You also could use three 1 watt Luxeon LED headlights (they're 4.5V each), and be able to be seen from the big island.

Actually 3 1W Luxeons run though a controller needs about 12v to work. If I remember the schematic I got with my 3W LED controller it needs 15v to run 3 3 watters.

Best yet those are available in LED for about $5 each.

At VIP auto (a major chain auto parts store) I saw the same style driving/fog lights in LED - I'd check those out for max batt life, prolly not as bright as the 55w halogens, I suppose you could have one of each, run the LED for normal conditions and to save power, saving the halogen for "high beam" use.

Lookin good man!

Just wanted to mention, at "Home Depot" or it's equivalent they have 12v DC halogen spot or flood bulbs w/focused housing, meant as a replacement bulb for home lighting - make a housing/mount for the connectors and the "spot" would make a great distance headlight - or one of each, flood for area light/spot for distance. They consume a touch less power and at $3.59 - it may be worth it to make a mount

I use the Walmart small driving light set, about $15US but as barelyawake mentioned, I removed
the bulbs and replaced them with one of each of the Home Depot bulbs--20W spot and 10W flood.
Using a 12V 7ah battery gets me about 3 hrs of use. I also use a tire scrubber generator with a
rectifier circuit to charge the battery on the go...buys me another hour or so. Also running led head and tail lights and a 10W mini bulb like above in a torpedo front fender light.
