New Helmet Mount Lamp Design
For an inexpensive helmet lamp, buy an 12 volt, 25 watt RV light bulb at
Home Depot (about $3.50). Attach a standard light bulb socket and a lamp shade to your helmet using pieces of wire hangers. various bits and pieces of steel, and cable ties. Power it with a 12 volt sealed lead acid battery that you carry in a back pack. The beam pattern is not ideal, as it doesn't illuminate the road at all, but it is a good "being seen" light. It cannot be powered by a dynamo. Not sure if it's legal or not, but admit it, have you ever not seen an illegally lit cyclist? Or have you ever seen a legally lit cyclist? Or have you ever not seen a legally lit cyclist? Whatever. I know it's a good light because I rode around my neighborhood and I asked my neighbors if they could see me and they all told me that they could, then they hurried their kids and pets indoors. I put up some images of this at "http://bicyclelighting.com" . I tried it last night while going to a Halloween party and it worked well. |

Nice Halloween joke. Thanks. -- Mike Kruger Here's a tip: Try to eat everything. You'll be surprised how much is edible --Darby Conley |

Hey, I wore it walking around the neighborhood with our group of trick or treaters, and it came in very handy. Easier than carrying a flashlight, though vertical clearance was an issue in some areas. I'd like to get a 12 volt compact fluorescent for next year as the 25 watt bulb only gets about 90 minutes of operating time from the battery. I could use a smaller battery or go longer. I saw some at "http://www.solarseasy.com/cfbulbs.html".
