Busch and Muller Topfire helmet lights

Busch and Muller's Topfire helmet lightsare a really neat way to get yourself a bit of extra visibility on the bike. They're easy to fit, effective and weigh next to nothing.

The kit contains four single red LEDs connected to a battery compartment housing a cheap-to-replace 2032 button cell. The LEDs sit in the rear vents of your lid, held in place by double sided sticky tape, and the battery clips to a strap or, in my case, the centre strut of the rear retention system.

Once it's on it stays put. I was worried that the tape wouldn't hold the LEDs in the wet, but there's been no end of wet and they're still there. The battery compartment twists to turn on and off, it's easy to do without looking and with gloved hands, no more difficult than adjusting the retention system on a normal helmet.

There's one mode, flashing (twice a second), and battery life is a claimed 100 hours. I've been using them for a month of night-time commutes home and they're still going strong.

Once the battery dies you can pick up 2032 cells online for next to nothing. The LEDs aren't super bright but they're very effective in the dark and a useful bit of extra visibility now the nights have drawn in. And at 18g you're hardly going to notice the extra weight, are you?

My first set lasted a few months, the second set nearly a year. Sweat and rain gets into the battery pack and the terminals rot. It also took glue to keep the lights in place as the sticky tape supplied is not up to the job. The biggest problem however is that the LEDs are very directional and can only be seen directly from behind. There are better options out there.

Knog lights can generally be easily mounted on most helmets.

I run a fibre flare on the rear of my helmet. The straps are v stretchy, piece of pee-pee to fit it.

Anyone else think the picture at the top resembles Megatron from the new transformers films?? May have to buy them just for that :-P

Clas Ohlson do a helmet light for about a fiver. Good side visibility. My cycling buddy has one and I hate it when I am drafting him at night on training rides.

I rather like the Topeak Headlux helmet light which has red to the rear and white to the front. My issue with that is that it does form an obstruction on the helmet that can catch, I'd try this out except I'd still want a white to the front.

(BTW the topeak suffers in the downpour, goes to steady instead of flashing and you may have to remove a battery to get it to switch off)

Busch and Muller Topfire cycle helmet LED Lights. Great idea, let down by the fitting of the LED's to the helmet. Basically the adhesive tabs supplied with the product are not up to the job, so if you purchase factor in the cost of finding a suitable product to glue or affix the LED's to your helmet. Plus the LED's are quite directional, it's shame they don't have 180 degree cover and not sufficiently weatherproof.
