Hippies on your head!
At the 2000 Mont 24Hr Mountain Bike Race
, a 2nd light was compulsory. It didn't have to be anything more than
a maglite , or even a $5 K-mart jobbie, but dammit, how am I supposed to
blind other competitors with one of those things?
The solution lay in something I'd had lying around for years - an old
mining lamp, which I'd used as a caving lamp. These things had a 4.5V lead
acid battery that you wore on your belt, and a really schmick light with
a halogen mainbeam and a conventional low beam that clipped to a dedicated
bracket on your helmet. The battery had long since
snuffed it, and 4.5 is a silly number of Volts. No, the
One True Path was 6V, since I could get appropriate (sort of) bulbs...
A quick visit to Jaycar provided
the neccessary supplies - a 6V 4Ah battery, a 7.2V halogen globe, and a
6V conventional globe, along with a couple of connectors that weren't compatible
with my 12V systems, since I didn't really want to accidentally put 12V through a bulb
rated for 1/2 that. A little chopping, a little soldering, a little filing
of the reflector assembly so the backup bulb would fit, and voila! The light
was working.
Of course, a working light is useless without a way of attaching it, so
a little more ingenuity was required. Some scraps of sheet metal that were
in the garage were bent and riveted to make a bracket, and a couple of sleeping
bag compression straps attached it to my helmet... Weeee, let's go for
a night ride!
The 24Hr was the acid test (beta testing? That's for wimps!) for this
setup, and overall it worked well. The bracket was originally mounted too
low at the front of the helmet, meaning the beam shone quite close to me.
This is about where you'd want it for caving, since it helps to see what
you're walking on, but for cycling you want to see where you're going. A
stop at the halfway mark, where the officials had set up a light, allowed
me to remedy this. The only other problem was a dodgy connector - 5 minutes
work with a Gerber multitool fixed this one, and I've subsequently reinforced
the cable at this point to stop it stressing the connection.
This light is amazingly bright, with a very narrow focus. It's kind of
hard to ride with it on its own, but in conjunction with the bar mounted
V4.0 hippy lights , this is great
light!
