How many batteries do you need? Can you do a 4 hour ride? With both headlights, and one rear xenon strobe I can go 1:45 with a 5AH battery. To go 4 hours would require a 7AH battery and riding mostly with only one headlight on. 7AH batteries aren't much more expensive, but they are heavier. My commute is about 45-50 minutes so a 5AH battery is more than enough. For more details see: http://www.bicyclelighting.com |

I would be worried they would think you are a car far away with lights so close together. -- Knight-Toolworks & Custom Planes Custom made wooden planes at reasonable prices See http://www.knight-toolworks.com For prices and ordering instructions. |

Plus you can buy them at any Home Depot. How many batteries do you need? Can you do a 4 hour ride? Doug Toronto Steven; What's the beamspread on the lv504. I went to the intermatic website and there aren't any specs stated at the site. I have a Bisy and have uprated the bulb to about 5 watts and while the pattern is great, am looking for a bit better output without going to the 25 watt range. Perhaps eating more carrots will be of aid ;-) Regards Pat |

I'd call it a flood pattern, which is ambiguous I guess, but that's what it looks like. Much more stray light than the Bisy. http://www.fa-technik.adfc.de/Kompon.../vergleich.htm I'd say more like the Aufa pattern than anything. |

Well, there are 2 purposes of headlights. One is visibility - that is for other people to see YOU. And the other is illumination - so you can see things like pot holes, road kills, lil animals, and joggers. Both lights will give decent visibility. The LED will give just about 0 illumination. The halogen will give a little bit but not much. You need about 15 watts to give illumination and even that really isn't enough if you are riding very fast. More about what I'll be using it for: A) During the end of the summer and in the fall, I sometimes get a little overzealous and ride too far away from home for the remaining daylight. There is always some sunlight left when I get home, but sometimes not too much. In this instance visibility is important, although a little illumination of the road would be a bonus. B) Here in Wisconsin there are quite a few rail-trails with tunnels. This summer on the Elroy-Sparta, a friend and I rode through the 3/4 mile Norwalk tunnel. He had the 2.4W halogen, and it did a decent job of allowing us to ride very slowly through the tunnel instead of walking through. I'd be willing to give up a little illumination to get the much longer battery life in the LED. Will it be steep dropoff, as it seems you indicate? Thanks to everyone who responded to my post!

om... Do you guys really have that much trouble out there? Yes. I don't know where you live, but I'd be willing to wager that the amount of trouble a cyclist has is directly related to their location. Not just the traffic levels and the road networks, but even the ethic make-up of the area. I live in an area where many people learned to drive as adults rather than as teenagers, and are quite inexperienced. Also, a lot of them come from countries where cyclists and pedestrians are very low on the totem pole, and where motorists count on cyclists and pedestrians to get out the hell out of their way. Am I really leading a charmed life? Yes, so far. But don't rely on that. Put some good lights on your bicycle |

Oh-you mean the United States. The U.S. is great compared to China or Taiwan. |
