Head to BikeRadar’s round-up of the best helmet lights for our pick of the bunch. While many of these lights can also be used as handlebar-mounted units, for this test, they were specifically reviewed for use as helmet lights for off-road night riding. We also timed them all on maximum power to find out just how long the batteries last, and whether they live up to the brands’ claims. We tested how each light performs riding back-to-back runs on the same trails, comparing beam pattern, LED colour, ease of operation and, most importantly, light projection. By finger pressure or mouse click you can move the area on the map. With the cursor at the bottom left in the center you can view the weather over time. : National Oceanic and Atmospheric Administration's : National Weather Service. This is how the weather radar live works: The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. That covers everything from occasional use or as a backup light, to full-on, high-speed riding. Latest weather radar images from the National Weather Service. The lights chosen here have an output of 450 lumens up to 2,100 lumens. With prices ranging from £65 to £265, there should be something for everyone’s budget. We put six helmet-compatible lights to the test. Light and Motion VIS Pro 1000 helmet light bottom line However, in the last 10 per cent of the battery, the light goes through flashing and dimming modes, so the one hour, 30 minutes of full power is pretty accurate. I managed to get a run time of one hour, 44 minutes on full power, which is a little longer than claimed. However, it doesn’t quite have the punch needed for more technical mountain bike trails and spreads its power too wide. It has enough power to get you around trail-centre blue trails without drama. The reflected radar signal is measured by the radars receiver with a change in frequency. For example, a Doppler radar transmits a signal that gets reflected off raindrops within a storm. ![]() The VIS Pro 1000 will be more than adequate as a standalone light for double-track adventures. Doppler radar is a specific type of radar that uses the Doppler effect to gather velocity data from the particles that are being measured. Throw down the trail is adequate, but it illuminates the trail gently rather than providing the bright spot beam pattern needed. Of course, it’s possible to ride with this light by itself, but it would be best not to rely on the VIS Pro 1000 alone. This relatively broad beam makes it harder to punch through a brighter handlebar light. It spreads out its 1,000-lumen output, making it less useful than rival helmet lights. The wide spread of light doesn’t have a sharp enough focus point at its centre to help highlight and illuminate the sections of trail where you’re looking. The single spot-style LED has a 20-degree beam angle.
