I wish that I had seen this before I ever purchased a light. DIY but practical and very easy to implement for us non-technical types.

It's a long article suggesting how to use the item above.

bad advice, using white lights for the rear.

Also, they take up too much barspace and aren't really 'quick release' as they are attached to a battery pack that needs to be removed as well.

I doubt they put out much light either (17 leds) and there are plenty of multi led (53 leds) cycle lamps available anyway.

What is clunky and butt ugly ?

Jamming inspection lamps into bottle cages or cheap and nasty multi led cycle lights ?

Or both ?

One thing that bothers me about the use of two [dim] lights on the bars, is the Saturn effect. The Saturn effect [so coined by a physics teacher many moons ago] is the illusion that a vehicle is farther away than it actually is because the paired headlights are closer together than usual. For example:
*-* = a regular car coming toward me from 200 yards away
*---* = same car at about 100 yards
*-* = a Saturn at about 100 yards
*-* = those crappy Harbor Freight lights at about 20 yards

I have experienced this while driving my car at night on the highway. Check distance to oncoming vehicle, pull out to pass, get flashed - WTF? The car is literally half the distance away that I thought it was - I see it's a Saturn as it goes by.

If you want a cheap, effective setup, overvolt a 12V halogen and be done with it.

for the above reason I have one light on flash and one on solid.

Seriously ?

You only have cars and bicycles on your roads ?

You've never once seen a modern motorcycle with twin headlights close together ??

motorcycles often only have 1 light on for that reason I think. I often see motorcycles with only one light on.

If you see a twin headlight motorcycle with only one light on...it's not so that erm... 'slow' car drivers don't mistake them for a car..... it's known as low beam.

Early twin headlight motorcycles had low and high in both headlights, nowdays manufacturers seem to like fitting low in one and high in the other or low in one and high and low in the other (with one single element bulb and one twin).

Possibly it's easier to set up the beam patterns for different countries.

One of my motorcycles (it's german) has headlights designed for use in countries that drive on the wrong side (right hand side) and they can be set up for use in countries that drive on the correct side (the left).

I guess there are many possible reasons why the manufacturers set up twin headlights in different fashions including things like cost, simplicity of wiring, design etc...

Dumb idea. Buy a high powered LED light and be done with it.

I always thought one of those rotating amber strobe lights would be cool on a bike.

In the video there was also a blue flashing light in the front. That many flashers, including a blue one, will probably get you pulled over by the cops. I think blue is illegal in many states where emergency vehicles use them.

Most motorcycles sold here fall into the sport or cruiser categories. The cruisers typically have a single sealed-beam lamp, with dual filaments for high and low beams. The sport bikes are often single lamps as well, but will occasionally have separate high and low lamps side by side or one above the other. They are spaced close enough together that if both are on at the same time, they typically appear as a single point of light.
