Strictly a tertiary visibility aid, the Topeak Headlux is a helmet-mounted splicing of front and rear blinkies. It’s not quite a universal fit and the Velcro mounting straps need pulling really tight to avoid the unit drumming against your helmet when negotiating poorly surfaced roads. The high position and intelligently-designed lenses lock those perky diodes squarely at driver eye-level and they seem ultra effective to 50 metres.
Weighing 25g including CR2032 cells, the Topeak Headlux’s wraparound design doesn’t boast any laser guiding credentials but nonetheless, the plastics are of a decent quality and show no signs of scuffs/scratching despite everyday service. Their see-through nature reveals elementary diodes, board and switchgear but the soldering is meticulous.
The batteries live in the mid section, away from winter’s wrath, though silicone grease and a homemade doughnut seal improved connectivity while ruling out any potential problems later on. Mounting it or swapping it between lids takes all of thirty seconds.
Depressing its low profile, centre mounted switch engages steady, flashing or hybrid modes. Some suggested theirs quickly became erratic or unreliable but ours became more compliant with use. Bringing it alive mid-flight proved comical, though, especially wearing winter gloves.
The steady mode is polite and best reserved for riding well-maintained cycle paths, map reading and pannier rummaging. Drivers tended to acknowledge it fleetingly, whereas the flashing mode’s impatient chorus grabbed and retained attention from around fifty metres, further on clear nights.
Weather resistance is good, as distinct from great. It’s no substitute for mainstay lighting, and with lateral thought and simple attachment it translates nicely to tagalongs, trailers and recumbents, so often overlooked at junctions by unwary drivers.
Strapped to my low-slung Yak pattern trailer, ours remains in remarkably rude health despite wet roads, drenching from passing artics with the odd stone thrown in for good measure. Subsequent cell replacements returned run times of 44 and 66 hours in steady and hybrid modes, respectively which isn’t far removed from the 50 and 70 hours claimed by Topeak.
