However, when it comes to workmanship I was not impressed with this manufacturer. I bought a regular rear light from them and the light beam was terribly skewed. The LED positioning was substantially off-center so I wrote an email. The answer was that this is "normal". So I sent it back. Saw a clone, bought it just for a test and ... perfectly LED centering! Same for the next three I bought. The holder was also too flimsy IMHO. Same for the clones I bought and I added two serious bolts for metal plate mounting, threw away the clip thing. -- Regards, Joerg http://www.analogconsultants.com/ |

Andy I forgot to ask what you currently use for a rear light. The clones :-) Also classic Spanninga rear lights modified to LED. This type: https://images-na.ssl-images-amazon....L._SL1500_.jpg The old lights were the best because they have sturdy bolts to fasten them to the bike instead of flimsy plastic clamps. They also have a nicely screwed-on lens _with_ reflector instead of a clip-on lens that flies off during rough rides, so no rubber band needed. The downside is that they are now hard to find and one must modify them from those dim 0.6W incandescent bulbs to LED. What I did on the road bike to affix the Spanninga light was to make a metal holder which is fastened like an additional washer under the seat post clamp. Works great. I am planning to mount two of those lights in the back though because my rack now has an aluminum plate to hold such stuff. That would give me three redundant lights, two illuminating steady and one (the clone) flashing. All solidly bolted to that aluminum plate. This plate currently also holds a large wide reflector, seen from the side he http://www.analogconsultants.com/ng/bike/Rearlight1.JPG The battery-operated light below it will go and become replaced with the better lights that are currently up on the seat post. That prevents those from being blocked by cargo on the rack. The rear light on the MTB is currently only a single one but bolted to a similar plate with two M4 screws. It is also recessed to reduce the chance of rock hits. I am a strong believer in powerful bike lighting, also during the day (but only while on roads, no DRL on bike paths). This is why an 8-cell 18650 Li-Ion pack rides along on the road bike. 4-cell on the MTB, in a smash-proof ABS enclosure bolted to a home-made tail strut. -- Regards, Joerg http://www.analogconsultants.com/ |
