Step 1: Parts and Materials

Picture of Parts and Materials
Here's what you need:

1) Bike (I'm assuming you already have one...)

2) Christmas Lights - 25' length. Available in your attic, or any local retailer

3) Decorative Light - Star, Angel, anything that glows. Available at your local retailer

4) Lead-Acid battery - 12V, 7AH, from All Electronics:
Battery $22

5) Lighter Jack (optional) - I used a "Y" adapter and just cut off one of the sockets. You can buy a "Y" from All Electronics:
Adapter $3.65

6) Inverter - Just a small ~75W inverter should work, like this one from All Electronics:
Inverter $14

7) Crimp terminals - Also available at All Electronics:
Crimp Terminals $2.50

Total Cost: $20-$60
SLA batteries are dense (about 5-8 lb.). Motorcycle batteries or tractor batteries are heavier. If you have a rear cargo rack, I recommend using long hose clamps or coat hangers to tie down a battery to the cargo rack. If you bolt or attach a milk crate to a rear rack, it's really easy to put your 12v inverter, battery, etc together and seal them in a bread bag or something, to prevent water shorting them out. Then you can attach ornaments (christmas, holiday, new years, or other festivities) to the crate as well as the bike frame.

This is a couple years after the fact, of course, but I'm looking at building a similar set up to decorate a local landmark (see: http://facebook.com/larussellpump for an explanation).

I already have a battery similar to the one you use, albeit slightly larger and rated at 8ah (also featured in one of my instructables). I'm thinking of getting a cheapy Cobra inverter which puts out 400w.

My question is, what kind of run time could I expect out of, say, 2 strings of 200 regular, mini, incandescent bulbs?

I'd prefer the set up to run around pretty much 8 hours, giving good coverage through the evening. If my battery wouldn't run it, what, conceivably, would?

Thanks so much for any help/guidance.

The battery that you have in the picture, where's it from? It doesn't look like a regualr car battery?
he tells you what kind of battery and even gives a link to where he got it in the instructable.

I commute with a kiddie trailer at 4:00 am. I think I'll try doing the trailer. Thanks for the idea.

Very nice, I like it! Check out the one I did here. Mine was a lot more work, I see I could have gone a much simpler route!

depotdevoid, nice project. Mine was kind of a "use what I had lying around" approach... Yours is more of a custom high-tech version!
