Range rover? Should be good for offroad, plus you could dip them for road use. Good reflectors are always going to be large, unless some sort of diffraction grating (as on flat magnifying glasses) is used to shape light into a useful spread, it'd be lighter and more compact, but not as efficient as a parabolic reflector. I've never seen a bike light with an adjustable front lens and small but effective adjustable rear reflector, but I wish there was - it might stop "It's dazzling me!" whingers... I've tried being a respectful cylist, sadly, this wasn't reciprocated by disrespectful and ignorant drivers. Now, I just want to be seen and be safer when cycling at night. If drivers don't like it, they can write to "Points of view", or their MP or something. Edited January 7, 20224 yr by guerney

January 7, 20224 yr Author It's much easier for a driver behind to judge the distance of a steady red light. A driver is much more likely to notice a flashing red light. My solution : two lamps - one steady and one flashing - set reasonably far apart. Front lamps - As a pedestrian, cyclist and driver I ***hate*** these enormously powerful LED front lamps. They can be completely blinding (far worse than most car headlights). Their use as point-straight-ahead-death-rays shows no respect at all for other road users. I've just taken a look at mine, from the front in a darkened room, and crikey, yes, they are definitely an extremely bright, dazzling white, and yes possibly blinding. I was quite surprised as it's the first time I've ever taken an actual look at the light from a forward perspective. I just switch it on and go. Never have need to check as it's powered direct from the battery. Nothing like those old large metal ones, powered by their own batteries, which you'd slot onto the front of the bike. They were very mild by comparison. With that said, I certainly wouldn't be up for taking lectures from motorists who come at you full beam on an unlit road. I challenge any cyclist to stay fully orientated in direction before such a car passes.

How about filling empty space within, with non-electrically conductive ferrofluid to conduct heat to the torch shell casing, after adding heat vanes to increase it's surface area? Then air passing by at your usual 25mph night time speed would do the rest.

I challenge any cyclist to stay fully orientated in direction before such a car passes. Even my weak little 1.5 watt Junstar Bafang headlight looks dazzling when viewed in isolation in the dark, but they can't hold a candle to car headlights, even when they're not on full beam. Honestly, whingeing drivers complaining about cyclist lights being too bright for their precious little eyes, which don't see cyclists when they don't sport bright lights, need to gain a sense of perspective, wrapped up safe barging about in their cyclist mincing steel cocoons on wheels: https://www.pedelecs.co.uk/forum/threads/%E2%80%9Cexceptional-hardship%E2%80%9D-loophole-allows-drivers-to-kill-and-kill-again.42572/ Edited January 8, 20224 yr by guerney

January 9, 20224 yr each of the leds is rated for 1000lm but doubt they are running at full power so more like 6000lm real world but they all over rate the light out put Sorry, thought the lamp in your ebay link was the 8000lm one you were referring to, not the magicshine one you have in the you tube link. Those cheap ones coming out of China may claim 8 or 10 thousand lumen, but clearly they are well off that. Keep in mind a car headlight is between 2000-4000 lumen. So a wee Chinese bike light is claiming to have the power of a pair of the top end car headlights on full beam.
January 9, 20224 yr I prefer cycling at night - when else do cars reduce in number enough, for one to enjoy the road? Mind you, drivers are much worse during pub hours, and after they close... even blinder than usual - half awake and slow to react. This helps: https://www.amazon.co.uk/Hornit-dB140-V2-Worlds-Loudest/dp/B006TDEV20/ref= It's prevented many a collision with people and vehicles, also works on other animals. Gives you a loud retort to rude beeping *sshole drivers. Just bought a Hornit - it's loud!
January 9, 20224 yr Just bought a Hornit - it's loud! Yes it is! It projects really well too - I don't like the weird shrieking setting, the beep works much better IHMO because it sounds like a noise that a vehicle would make. But the beep is only 120db... still, it gets through car body shells and into driver ears. The little switch to horn jack plug does fall out occasionally, so best test before you ride out. I might ziptie that on or something. I beep everyone and everything pre-emptively, useful for alerting drunks wandering all over the road at night, but especially useful for drivers. Those two AAA batteries last ages. It really annoys drivers, which makes a nice change. A driver cut in front of me with millimetres to spare the other day and beeped, so I beeped back - I heard him shouting "What's he beeping about?"... and because traffic slowed and I had an ebike, I caught him up and shouted through his window that he should allow bicycles as much room on the road as a small car.
